Speaker 1

Welcome to Creature future production of iHeartRadio. I'm your host of Many Parasites, Katie Golden. I studied psychology and evolutionary biology, and today on the show brood X. There's often generational battles, boomers complaining about millennials, gen X complaining about zoomers, Zoomers duking it out with boomers in the thunderdome. But perhaps as we have our petty generational fights, we should stop to consider what's happening under our feet. Something is stirring.

In fact, millions of somethings are stirring. Rude X is about to emerge, and we should put aside our petty squabbles about whether millennials eat too many avocados or zoomers do too many tiktoks about avocados and prepare ourselves for brood X that has been waiting seventeen years to emerge from the ground. What is brood X? Should we panic? Must we accept brood X is our new leaders? And

how might we ingratiate ourselves to them? Discover this and more to we answer to the age old question, how is it fair that swarms of baby turtles are considered cute? But swarms of bugs are considered quote horrifying. Joining me today to discuss brood X and other mass spawning events is author of the book Where Am I Now? Actress and unofficial President of All Millennials.

Speaker 2

Mara Wilson. Welcome, Thank you so much for having me. I'm very excited to talk about this brood X. It sounds a lot scarier than it actually is, I think.

Speaker 1

Or is it. No, you're right, that's true. Yeah, it sounds scary. It sounds like this is our come upance as a specia and we're about to face the music, the very loud music. But no, it is it is actually very very interesting thing in evolutionary biology. So this brood X is a mass cicada blue. First, I want to ask you, mar how's your feelings towards cicadas.

Speaker 2

You know, I don't think they have them where I grew up, or at least not in the ways that they do on the East Coast because they so seventeen years so they were, because I do remember hearing about them when I was a teenager. Yeah, so probably when I was That was two thousand and four, so I would have been sixteen or seventeen, and I do remember spending my summer on the East Coast and I think that was the first time I'd ever heard cicadas.

Speaker 1

Yeah, yeah, I think we do get So I grew up in San Diego, and I think we get some cicadas there, yeah, but definitely we don't get the mass burning events that happens on the East Coast.

Speaker 2

I think, like, maybe i'd heard them before, but I didn't know what they were where, Whereas when I lived on the East Coast, like I definitely i'd heard cicadas and I knew what they sounded like, and I think, yeah, I was.

Speaker 3

I was like visiting family on the East Coast in two.

Speaker 2

Thousand and four, and I was like, what's this weird noise in the tree that seems to be everywhere? And what are these like dead bodies littered on the ground. So uh so yeah, so yeah, so I'm kind of indifferent to them. I don't think that they're They're like I I like the sounds of crickets chirping. I don't mind the sounds of cicadas so much. It is a bit overwhelming and it is a bit gross when like

their corpses littered the streets. But again, I haven't had to deal with that as much, so, so it's it's not you know, it's not as much of an annoyance as like as like coyotes are to me, or like or or like snails or things like that where I'm like gross, you know.

Speaker 1

Yeah, good, then you missed the Giant Snail episode that was.

Speaker 3

Yeah, I'm oh God, snails draws me out so much.

Speaker 2

I'm sorry, Katie, but I'm gonna have to skip that episode because I think they're I think they're the grossest things ever.

Speaker 1

My friend Bridget also she's been on the show, also disgusted by snails. Yeah, so I won't tell you the story about when I was a toddler, I used to just eat garden snails.

Speaker 3

Whoa, I mean that's that's you know, that's that's French. That's it it is.

Speaker 2

Yeah, that's gourmet, very bask Yeah exactly, now I would.

Speaker 1

I can't eat I can't eat escargo. Maybe it's because I like, as a kid, it's just like, you know what, I've eaten enough snails. I'm good.

Speaker 2

Yeah, I've heard it's also not very good unless it's prepared a certain way. So it's like it's like one of those things that turns out kind of rubbery and and.

Speaker 1

Yeah, yeah, I don't know how I managed. The reason, uh, I know I ate snails because I barely remember anything from that age is that my mom said that I would come, I'd go out in the yard and then come back and I had like snailshell in my face. Oh, I'm sorry, I'm sorry, Mark, I can't too.

Speaker 3

Yeah, I'm gagging.

Speaker 1

I don't I haven't done that in quite a while.

Speaker 3

I know, I know. But just the idea is.

Speaker 1

Is, yeah, well, that's that's your gross out of the episode. Than Yeah, for I figured there would be one. So yeah, so cicadas maybe not that gross, but maybe a little intimidating. So this spring in the US, we are welcoming millions of cicadas into the world in a mass hatching event. So yay, Yeah, I guess, like before we talk about the mass s bonding, let's talk about like, what what even is a cicada?

Speaker 3

Right?

Speaker 1

They are a very loud bug. They are a true bug. They're like we call a lot of insects bugs, but there are just a few species that are known as like true bugs. Yeah, and others that I guess are wanna be bugs.

Speaker 2

I don't know, but is it like how there's no such thing as a fish Like I always thought like bug was kind of like a fake name that was just sort of grouping a bunch of different creatures together.

Speaker 1

There's actually there there is, actually there is such a thing. There is actually true bugs. Yeah, I mean taxonomy gets very I don't know, there's a lot of gray areas. There's a lot of like you know, like with you mentioned with fish, there are like reef and fish and then but a lot of things that aren't fish are called fish, like jellyfish are not fish. They're nidarians. We're actually going to talk about some more Nigerians at the end of the episode, which will be very strange. But yeah,

so so cicadas true bugs. And they're actually related to leaf hoppers, those cute little leaf shaped bugs that are really good jumpers yea, and they come in really interesting shapes. So I think we did an episode on leafhoppers before. But yeah, they are very interesting bugs, very beautiful they are.

Speaker 2

That's like one of the things that like blows. It's like like if you ever want to blow like a four year old's mind, you know, show them a picture of a leaf hopper. Yes, I remember, like I remember being in like preschool, in kindergarten and going to I don't know if it was a nature preserve or what, seeing leaf hoppers and stick bugs and just losing my.

Speaker 3

Like what how does this exist?

Speaker 2

Does?

Speaker 3

How is this a thing? Yeah?

Speaker 1

It looks Yeah, they look like made up bugs that someone like paper machade together.

Speaker 3

Yeah.

Speaker 1

It was like, yeah, I'm just gonna make a bug that's a leaf.

Speaker 3

But I never would have thought they were related to cicadas.

Speaker 1

Yeah. Yeah, Like leaf hoppers have that sort of triangular shape, so they're different. So there's there's leaf bugs that have the sort of flat leaf, and then there's leaf hoppers where they still look like leaves but they're like kind of folded up leaves where they have that triangular shape, and they're really good jumpers. If you've ever like you may see something that looks like a little leaf, but then it has like little legs, and then you try to pick it up and then it just almost disappears

by how quickly it can jump. That's a leaf hopper. And cicadas are sort of like bigger versions of this, except they don't they don't typically camouflage as leaves. They have wings in a thick, triangular body. There are many species of cicadas, and they come in a variety of colors, from black to brown to green. There's even orange and

blue hues. And they are fairly decently sized. So the smaller species are about zero point seventy five inches or about two centimeters, and the largest species can be over two and a fourth inches long or five point seven centimeters, so you know big.

Speaker 2

Yeah, I've seen them before and they are pretty big.

Speaker 3

The ones that I've seen were pretty big. Yeah.

Speaker 1

Yeah, like you don't want to get hit in the face, like when you're when you're on your bike, just for example, no reason.

Speaker 2

I mean, I haven't had that happen, but I have had. What are the Jerusalem beatles or not Jerusalem?

Speaker 1

They're like, oh yeah, what are Erusalem crickets?

Speaker 3

What are It's not Jerusalem crickets? What am I thinking of? They're like the big flying there's these big flying things that are like big and lou they look like giant bees.

Speaker 1

Oh yeah, those are I.

Speaker 3

Don't know what they're called. We have them in southern California.

Speaker 1

I think they're June. Are you thinking about June June bugs.

Speaker 2

No, they're not June bugs because they're they're like they like fooled in on themselves. They they like roll up and they fly and they're like brightly colored and they look like they're like some kind of flying beetle. And but I've gotten one in my hair before. Oh yeah, I was like by my friend's pool and one got

caught in my hair. I've also I've also found multiple spiders in my hair before, which I think, which I think means or only one at a time, but like I've found a spider in my hair once and then like I can't even remember it happening. But just last year, I found a spider in my hair and I was like, oh no.

Speaker 3

Not again.

Speaker 2

And I was like, wow, that's a weird thing to think. I'm just croving my goth side like up spider. I got a spider in my hair again.

Speaker 1

Oh no, yeah, oh gosh, yeah, I have I have bad like luck with things getting in my hair too. I was at well, I won't name the restaurant so I won't get sued, but it's that a burger restaurant, and I felt something land on my head and I was like well that's strange. And I just sort of mindlessly reach up and pick it up and it's a giant cock crouch.

Speaker 3

Oh god.

Speaker 1

Yeah. And I was like, waiter, there's a cock crouch. Uh that fell on me? And he was just like, oh, I'm sorry. I was like, you might you might want to look into that, like check it out.

Speaker 3

I don't.

Speaker 1

I generally don't mind bugs. Like if a spider gets on me, there's an initial startle reflex. But it's something about it being in the hair yea that I hate, like like emerging from your hair, because you're like, it.

Speaker 3

Wasn't emerging in my hair.

Speaker 2

I just and it was a tiny spider, but yeah, the idea of it emerging from your hair feels like a like a creepy urban legend.

Speaker 1

Right, yeah, exactly, like the oh oh what's that the grudge you know? Yes, exactly, the fingers cut.

Speaker 3

The tiny spider. I looked at it. It might have been a fig eater beetle.

Speaker 2

Okay, yeah, because it was big and iridescent and that getting caught in my hair. I did mind that. I was like, you are too big. Get out of my hair right now?

Speaker 1

Yes, yes, no, no, I've I've been smacked by it by Yeah, those.

Speaker 3

Are annoying and they just they just it's just like, you are so big, how can you fly?

Speaker 1

Yeah? Exactly. I mean like that's how I feel about cicadas too. They look too eaty to fly, but they are. They are lighter than they look, and they have big wings. Even though like maybe getting smacked in the face or having them land in your hair might be unpleasant, you don't really have anything to worry about because they are vegetarian vampires. They will not suck on human blood. They only suck on tree blood or sap out of roots and tree twigs, so they thankfully they are not out

for human blood. That's good to know.

Speaker 3

It is good. If they were, we would all be screwed.

Speaker 1

We would definite Oh we'd be so dead. Uh So, the extremely loud calls they make are due to their bodies basically being designed like an instrument. So males sing to attract females. So that loud, droning buzz you hear in the summer that can be ear splitting at times. Is males going come on and get some of this to all the females trying to attract them.

Speaker 2

It's kind of like a rising and falling sound, right like do do.

Speaker 1

Yeah, yeah, yeah, it kind of sounds like a little tiny buzz saw that like little little forest gnomes are doing some serious high rises in the forests with the little teeny tiny buzzsaws. But yeah, it gets very loud, I mean gets as loud as a buzzsaw. Like it's very very loud.

Speaker 3

Well, because there are thousands of them right.

Speaker 1

Well, even a single one can produce a very loud call, and then when you combine them it, yeah, it can be deafening because one cicada can produce a sound that is about almost as loud as a chainsaw. Wow. Yeah, So crickets and other loud sound making bugs and other like, there are lots of animals that can make loud sounds. Often use a technique called stridulation to produce their call.

That's where they rub their wings or legs over a ribbed body structure and kind of like play themselves like one of those wood scraper instruments.

Speaker 3

Yeah.

Speaker 1

Remember in school when they made you sit in this circle and you're like here, you get this wood block that you d you get this like ribbed wood thing that you like scrape back and forth you get the triangle, and like they would only entrust the triangle to the non annoying kids, yeacause like otherwise the situation would get out of control.

Speaker 3

That was a privilege, Yeah, that was, yes.

Speaker 1

Definitely, because otherwise it was just like clin clan clan, cling, clang and pandemonium. Yeah, like that that wooden thing that has like the grooves in it and you like rub the stick on it. It makes that like noise and it's like kind of the lame instrument that you get and you don't really love it. But that is how a lot of crickets, and that's how other animals will produce that loud noise through stridulation. But cicadas don't use

this technique, like they are actually different. They don't use stridulation. They instead have specialized structures in their exoskeleton called timbals. So timballs are these membranes that are connected to muscles that can vibrate them rapidly, producing a very loud sound. In fact, cicadas are the loudest insect in the world. So it's kind of like you know those like big metal sheets that you shake to make it sound like it's thunder.

Speaker 2

Oh yeah, yeah, I've seen that happen, like like I was on I worked on I remember where on a movie once and we we were on this this lot that used to be like an air force base I think, and there was a pool in there and they made thunder sounds by putting a giant sheet.

Speaker 3

Of metal in the pool. Oh wow, and it's like really scary echo.

Speaker 2

Yeah.

Speaker 3

I was always amazed by that.

Speaker 1

That's interesting. I didn't realize they actually put it in submerged it like in water though.

Speaker 3

Oh it wasn't in water. It was an empty pool.

Speaker 1

Oh I see, so it would would like the resonance of it. Yeah, that's cool.

Speaker 2

It was really cool. I you know, it was one of those like oh that's how they do that kind of thing.

Speaker 1

Yeah, yeah, that would be I feel like that would be spooky though too. There's something about like big empty rooms and then like loud sounds in them.

Speaker 3

It was very spooky.

Speaker 1

Yeah, yeah, it spooky. It's like the idea of like going to a an abandoned theme park and then all of a sudden, like the the carousel just starts up and it's just music and an empty and then you're like uh oh well, zombies aren't gonna come now.

Speaker 3

Yeah, exactly, exactly. You know, what have you done?

Speaker 1

Yeah? But yeah, so so that these timbals kind of work like those big metal sheets and but they're there. They're smaller and they vibrate them much more quickly, and so you get that. I don't know if you'd call it high pitched, but sort of medium pitched, like buzzing humming sound. Yeah, and uh, and I provided you with lovely images of cicadas and like a little a little animated textbook illustration. That shit, I don't know how helpful. This animation is all included in the show notes so

everyone can see it. But basically it's showing like, look, it's this membrane and it goes it like sort of wobbles in and out.

Speaker 2

I think I find it really interesting. Also, I love that it's from a site called cicadamania dot com.

Speaker 1

Everybody has subscription. Everybody love Yeah, I'm actually subscribed to Cicada bi weekly. But yeah, it's it looks and it's interesting because it's it's kind of ribbed structure, looks mechanical, it looks like a machine part. In fact, the whole cicada looks very robot like today. It's like an alien machine, you know, kind of like a mixture between organic and machine, which I find pretty cool. But yeah, so that's how that that sound is produced. And just just for fun,

I will play a really loud cicada. I'll make sure it doesn't it's not gonna blow out your ears because I'm going to control the volume, so don't worry. But you know this, it's it sounds like construction work. Here is what it sounds like.

Speaker 2

It to me, it sounds almost like somebody revving up a motorcycle engine. Yeah, because it kind of it kind of goes like, yeah, there's like sort of a rise and fall.

Speaker 1

Yeah, no, exactly. Yeah, it's like little again, little forest gnomes on their massive hogs, just like reving around, yeah.

Speaker 2

Trying to get women's attention, which like was probably yeah, I mean probably what a lot of.

Speaker 3

Dudes on motorcycles are trying to do.

Speaker 1

Yeah, you're right, you're right. Cecanas are very much like like dudes on motorcycles going.

Speaker 2

Yeah, just making some noise. Yeah that's yeah, that's that's what it seems like to me.

Speaker 1

Yeah. So, so fellas and ladies out there, if you're trying to seduce someone. Uh yeah, just like make really loud buzzing noises. I think it'll work. You've got the creature feature guaranteed that that'll that'll get you some phone numbers.

Speaker 3

By a motorcycle it. It'll definitely attract some people, for sure.

Speaker 1

Or a buzzsaw, yeah, or.

Speaker 2

A buzzsaw well, yeah, if you just stand around with a buzz said, I don't know, yeah, I do know how many people that'll attract to you.

Speaker 1

But but very special people, Yes, it'll be. It'll be a match made having once you find someone who appreciates you do. Yeah, in a forest, maybe then it's like, oh, you're a lumberjacket in the middle of it, in the middle of the street. Maybe not.

Speaker 3

Yeah, I'm not gonna make not gonna make friends.

Speaker 1

So now we know what cicadas are, and so we are ready to welcome millions and millions of new cicadas into the world this spring. It's like, you know, spring is always associated with cute little bunnies and cute little baby chicks, but why not cute little cicadas. So the spring is very special because the periodical cicadas are having their moment. So there are a few species of cicada that have periodical bruits, so a mass brood that stays in stasis underground, often for over a decade, and will

emerge altogether in one big party. So right now in eastern and Central US, cicadas that have been resting and developing underground for seventeen years will emerge fully grown and ready to mate. So if you're seventeen years old and listening to this podcast, like, these cicadas are the same age as you, They've just been your entire life, have been waiting underground to emerge.

Speaker 3

Oh so maybe so maybe I was born in a cicada year.

Speaker 1

You could have been, Yeah, because I think.

Speaker 3

I turned seventeen the last time.

Speaker 2

Oh wow, So yeah, maybe so maybe you're cicada baby exactly.

Speaker 1

So, this group of emerging periodical cicadas this spring are called broodex, which I love how menacing, Like I love how scientists don't shy away from naming things like menacingly do they don't.

Speaker 3

I mean, of course, you have to.

Speaker 1

Lean into it, you know. Yes, I love the book lean In by a Cicada, And it's just like on the cover, looking professional. So this group of emerging periodical cicadas will emerge around May of this year in Delaware, Illinois, Georgia, Indiana, New York, Kentucky, Maryland, North Carolina, New Jersey, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia, Michigan, Washington, d C. So if you live in any of those places, congratulations.

Speaker 2

Yep.

Speaker 1

There'll be millions of cicadas coming out this spring, and they will be extremely loud because they are looking for mates. Basically, what happens is they'll pop out of the ground, mate, lay their eggs, and then die in a few weeks. So the males will make their characteristic buzzes and the females will flick their wings, which makes us kind of like snapping sound like a fingersnap, much louder, and that is signaling to the male that they are enticed by

their revving sounds. And then they go and mate, and then the female will lay the eggs in the branches of trees, and shortly after that, the adult cicadas die because that's that's it, like that that's their They've had their big party and then they're like, well, I'm out here, and then they die and that's why there's a bunch of Mario were mentioning you found a bunch of cicada corpses. Yeah, now you'll also find often like a bunch of uh

they're not necessarily corpses, but the final molting. So it's like they molt out of their various life stages. And so if you find sort of a hollow sort of kind of like amber colored, like it looks like sort of a yeah casing.

Speaker 2

I remember what they look like because of the game Niko at Sume the Cat collecton game. One of the cats, like the cats will give you little treats and it'll be stuff like a broken collar.

Speaker 3

It's the kind of stuff cats will bring you, like like a a.

Speaker 2

You know, an old an old you know, a shoelace or a broke half a mouse and yeah, exactly. And and one of them is actually a cicada MOLTI oh wow over cicada morting. And I remember I saw that. When I first saw it, like brought back so many memories. I was like, oh my gosh, I haven't seen one of these in years, but I know exactly what it is.

Speaker 1

Yeah, yeah, so they they they you need to connect me with this game. Because I need to play any game that makes a cicada reference.

Speaker 3

Yeah, it's the nico atsume. It's the cat collector game for I love this. It's very cute.

Speaker 1

Yeah, I gotta, I gotta check it out. Yeah, this episode is not sponsored by this, but if you want

to sponsor us, get at me. So you'll find both the cicada corpses, which you can tell if they're they're the corpse because they are actually they have the full wings and I think the ones in the US are sort of blackish blue color and then their wings are are lined in a bright orange and so that's that's the adult form of the cicada, whereas the casings, like the molted cicadas, is sort of it'll be this like

kind of translucent amber color. And the wings are clearly not fully developed on these because in their earlier stages of formation, the wings are little and they're not functional yet because they get bigger and bigger with each molting.

Speaker 3

So they they traveling.

Speaker 2

They don't travel in groups, but they like live in groups, right yeah swarms, yeah, because they I remember hearing them altogether.

Speaker 1

Yes, yeah, I mean like this is the this is sort of the entire point of this mass emergence from the ground is that they emerge all at the same time, basically millions of them, and then all mate at the same time, lay their eggs at the same time, and then that'll start the process again.

Speaker 2

So yeah, because because I bet like females probably aren't that discriminating when it comes to Yeah.

Speaker 1

They can't actually be because they have the they have the luxury to be discriminating because they're so many males, right, So, like they'll listen to these these calls and if they like the song, like if it's it's like, yeah, that's a that's a nice that's a nice uh motor reving sound. Uh, they'll invite the mail over with the wing flicks and then they'll mate.

Speaker 2

So I just feel like, if you, if you do your wing flick at like a group of guys, who's gonna know how do they know who it is? No?

Speaker 3

Not you, that guy, that guy, No, that one, No, that one over there, No, not you.

Speaker 1

Yeah, that's a really good question. I'm not sure. I would imagine it may have something to do with timing, Like they hear a call and then they sort of do a wing flick at them right after their call. But yeah, you're right, like there must be some that's a really good question. I wonder if there's any research onto like how they are able to like directionally locate where the stuff is coming from. I'm sure they probably have some a very interesting auditory system.

Speaker 2

Yeah.

Speaker 1

There, their auditory system actually also works as a resonance chamber. So it's like they they have this very complex little machine apparatus. So I wouldn't be surprised if they have some very complex way of being able to differentiate the direction of sounds so that that would make it easier. I mean, that's yeah, that's a really good question.

Speaker 2

I went to theater school and very familiar with resonators, with using your vocal resonators and so so.

Speaker 1

Yes, but what now what you call me?

Speaker 2

Just let the the using, Yeah, using using the different parts. Yeah, that's that's Resonance is something that you know, I admire and other creatures.

Speaker 1

They're natural born actors, but they yeah, but especially.

Speaker 3

When they live and die on the stage. Yeah.

Speaker 1

Uh. And also with like how many of them are trying to.

Speaker 3

Exact part Yeah, yeah, it's true.

Speaker 1

It's true when the female lays the eggs will actually lay them in the branches of trees and then again the adults kid was like, well, we had our big party, now now we're out, and they die. And then when the eggs hatch with this little teeny nymph like a baby cicada, the nymphs will fall to the ground and burrowed down a couple feet near the tree roots, near the plant roots, and then they will wait another seventeen years before they emerge again. Underground, they live off the

juices of the tree roots, which is called xylum. Basically, like I said, they are tree vampires and they take years to fully mature. So they go through many stages of molting and transformations from the nymph form, which is the young wingless stage after hatching two adults where they have the full wings and they're ready to party. So they slowly develop those wings which with each molting, and then once they've reached their final stage of maturation, which

is about at the same time. Because again they were all the eggs were laid at the same time, they all went underground at the same time. They're all synchronized, which is incredible. Yeah, they will start to burrow upwards and they test the temperature of the earth and once it is above about sixty four degrees fahrenheit or eighteen degrees celsius, they're like, yep, temperature's right out. We come.

And then it happens again and they actually leave a bunch of holes in the ground, which for me, that's like the spookiest part. It's not seeing all the cicadas. It's like seeing the holes. Like do you ever have you ever read a ging Eto like his horror comics.

Speaker 3

No, I don't think I have, But I mean that does sound creepy.

Speaker 1

There's a horror manga where it's like all these human shaped holes in a cliff face and like people like go inside and just get sucked up. It's kind of it's just like all these like little cicada holes. It's just it's a little creepy. That's I don't know why, but that's the part that kind of creeps me out. And it's not it's not tripephobia. I don't have that.

Speaker 3

That's the the hear of holes.

Speaker 1

Yeah, it's it's not really that. I think it's just the knowing what they are. Like that's where like this brood comes out from I don't know. Yeah, it gives me the shivers.

Speaker 2

I mean, I feel like if you grew up in southern California or or you know, anywhere in the Southwest, you probably holes in.

Speaker 3

The ground mean snakes.

Speaker 2

So I always, you know, my dad would always say, never put your your your hand or foot somewhere you can't see.

Speaker 1

Yeah. No, that's a good point. Yeah, because like I remember when I was a little kid and I was like digging around in the dirt. I found a hole. I was like, oh, I'll dig down in this hole. Scorpion, scorpion. Yeah, don't you.

Speaker 3

Yea, yeah, don't do that. That's I have.

Speaker 2

I have family that live in the desert and they're just kind of like, well, the cat killed another scorpion today, Yeah, And scorpions are so common to them, and I'm like, I'm like, I'm like, that's a bit overwhelming for me.

Speaker 3

Scorpions are. I think they're fascinating and cool, but but I'm I want them. I wouldn't want them to be doing battle with my cats or me.

Speaker 1

Yeah, they're great parents. Scorpions are, but they I don't want them in my room. I've I'm like in my parents' house where I grew up, where actually I am right now because I'm visiting my parents because the vaccine. Hooray. We're right next to sort of this arid canyon area. And so for whatever reason that bugs loved my room.

Maybe they could sense a kindred spirit. But I would get like scorpions would get in there, and it's like it would only be my room for some reason, or maybe I was the only one looking around for scorpions. But it's scorpions. I got, like a pleinarian once. It's like weird sort of warm thing. And I got the you mentioned. I think it was a misnom where you

were talking about the fig beetles. But yeah, but Jerusalem crickets are around here as well, so I got got one of those those are creepy their faces, something about I don't know, but yeah, so I got a bunch of weird bugs, including scorpions. Never a cicada though only heard them from a distance. Speaking of bugs and them encroaching on us, you may be asking, why do they do this mass brooding event? Is it just to scare us? What's going Is it an intimidation thing? Oh god, why

are they doing this? So it's interesting because most cicada species aren't like this. They don't lay in wait for seventeen years and then emerge on mass like they live for a few years, and they have like annual mating cycles, just typical stuff. The periodical brooding cicadas are interestingly different, Like their whole name is based on this brooding habit. They're called magic cicada, which sounds like it's like magic cicada, which is I love, But it actually comes from the

Latin maygui or magi. I think it's magi, yeah, which means to a great extent. So it's basically saying like, there's a bunch of them, But I also like to think that it's because they're magic, just like magic cicada.

Speaker 3

Yeah.

Speaker 1

But the purpose of this huge brood emergence is probably safety in numbers, right, there are so many of them. As an individual cicada, you're statistically unlikely to be preyed upon in such a huge mass of others, And it makes mating easier because you just have one big meet and Greek party with millions of sexy singles in your area.

Speaker 3

Exactly.

Speaker 2

It's what everybody everybody like, you know what people be like, you know, me and my homies. Once we get the vaccine, yes, of course it's not going to be like that. It's much more going to be like you know, us, us slowly, you know, climbing out of.

Speaker 3

Arcade where we've been hibernating.

Speaker 2

Yes, it's probably not going to be as fun and sexy as the cicadas.

Speaker 3

You know what.

Speaker 1

I didn't make that connection until now, but you're absolutely right. Now it's like a metaphor for emerging from quarantine. Yeah, we're coming out of our holes that we've been in for which feels like seventeen years, but it's been over a year. And then we'll probably have a mass meeting of it. And we should definitely call like all the babies that happens because of like after the quarantine, Yes, one like mating, we should call them brute as.

Speaker 3

They should be brute as.

Speaker 2

Yes, that would be That would be a great and and yeah, that would be a great, a great name for them, I think, the babies.

Speaker 1

And they would share, they'll share. Oh and oh my god, this is so perfect. It's like when nature is just poetic, because you're going to share a birthday with millions of cicadas. Yeah, I have a bunch of cicada babies were born like well, I guess not exactly, because they'll be conceived now, they'll they'll there's gonna be like, n enough delay.

Speaker 2

Quarantine has been long enough that there are you know, conceived in quarantine babies.

Speaker 1

That's true. That it's true. I thought there wasn't, like there was expected a baby boom, but there wasn't because people didn't feel like having a child. There the thunk there might still be.

Speaker 2

There might still be in the next but yeah, but probably it was. It was a bit too depressing.

Speaker 1

I think there's good. I think the celebratory we're out of quarantine baby boom is gonna be much bigger. I mean also because I think probably a lot of people wanted to have children and then we're waiting until after quarantine had so like I imagine a lot of them are going to be planned pregnancies of like, hey, we're out of quarantine now we can start our families. Yeah, exactly,

and so they're gonna be Yeah, it's it's beautiful. Your babies are going to share a special a special year with the millions of cicadas that are also going to breathe this year. Yeah, Cicada generation a wonderful It's just it's beautiful. It's it's like a poem.

Speaker 3

It's it's Yeah. They're synchronized, you know, much like the cicadas themselves.

Speaker 1

Now synchronized with the cicadas. So we're just gonna slowly become more and more cicada like, uh so going. Yeah. Another proposed theory for why they have such a long brooding cycle is that it makes it hard for predators

to adapt to your weird intervals. So like, if you are only like you only emerge every seventeen years, evolutionarily, it's kind of difficult for predators to have, Like they don't have a lot of predators don't have a lifespan of seventeen years, so matching up with that and being able to develop specific evolutionary traits to be able to

prey upon you is harder. Although some biologists disagree with this theory, They say, like, well, there's actually a fungus that has developed that can specifically prey upon these periodical cicadas, So obviously there's you know, but I still think that like, yeah, obviously fungus like probably because it's under the ground and.

Speaker 3

Guy are terrifying.

Speaker 1

They are, yeah, they they there's no defeating fung guy, Like that's the final boss. Like we'd like to We're like, oh, no cicadas, no cicadas, we don't have to worry about them. Fungi that's what we got to worry about. Yeah, that's what's that's the zombie virus is not gonna be a virus. It's gonna be a fungus.

Speaker 3

Yeah, like the most terrifying.

Speaker 2

Like I think about how I'll walk outside and I'll see mushrooms pop up out of nowhere one morning, and then the next day they'll be gone, and I'm.

Speaker 3

Like, how did you do that? How did you pop up and then go away?

Speaker 2

How? It's it's I I do not understand them. I have respect for them.

Speaker 1

Yeah, I'm not. I'm not a fung guy expert as much as I wish I was, But yeah, they they there's something about them that spooks me because they're not they're not an animal, but they're not really a plant either. Yeah, they're in that in between zone of spookiness and yeah,

so especially the parasitic fungus like cordyceps. Yeah, spooky because that goes inside an ant's brain or other insects make uh like takes over their brain makes some climb up of tree brands and then sprouts spores like right out of their brain. That's what the Last of Us that game, the video game about zombie apocalypse like that that the Last of the Space there zombie infection on the cordyceps.

Speaker 3

Oh really, Oh that makes sense.

Speaker 2

Yeah, I've heard about about the Last of Us, but nobody has has told me that that that.

Speaker 3

Yeah, that sounds really cool.

Speaker 1

Yeah it is. I really loved that aspect of the game. It's like the biological meshing sort of these biological facts. Yeah, they're they're the science fiction.

Speaker 2

We we we kind of understand bacteria. We we kind of understand viruses, but yeah, like fungi and like what are they those things.

Speaker 3

Are those things are?

Speaker 2

Are?

Speaker 1

Those are the misfolded proteins that that just like, yeah, causes a ruckets in your brain.

Speaker 3

They don't like that.

Speaker 1

But I do think, like, aside from from fun Guy, which are not a fun guy get uh you know, I think that that strategy of like if you lay in wait for like seventeen years, yeah, like birds aren't going to know what to do about you, Like their live spans are typically not seventeen years. Long, so they're not going to have any memory of these brooding events. They're not going to know like when to come and pray on you. So I think that maybe that is

part of the strategy. Interestingly, sometimes there are stragglers who either come too early or too late to the big brooding party. So it's not perfect. You know, nobody's perfect, pobody's nerfect. And that applies to cicadas too.

Speaker 2

I feel like i've heard them before. I've heard like like a soul. Yeah, yeah, I feel like we get that. Like we used to get the they're not actually June bugs, but we call them June bugs in yeah, in California, and like once or twice we would get a June bug that was late.

Speaker 3

My mom was like, oh sorry, dude, you're late.

Speaker 2

It's not June anymore. And yeah, kaidas eat here. Sometime you'd hear like one and it was just like, oh, that's so sad.

Speaker 1

Yeah yeah, it's like anybody is still out here. Yeah yeah.

But what's interesting is if there's enough stragglers, because there's so many of them, even if you're a straggler, the chance that there's going to be another straggler is pretty high, so sometimes there are enough of them that they actually successfully mate like a group of them, and then they can get off sinc a little bit from the rest of them, and that can actually start a new brood that also they still have like the seventeen year cycle, but because they're like off sync just a little bit,

they start like a different brood that will actually hatch different years. So there are many different cicada broods, so broodex is not the only one. There are cicada broods that emerge every seventeen years. There are some that also emerge every thirteen years, so slightly different species.

Speaker 3

Yeah, because I know.

Speaker 2

I've heard cicadas at times that weren't just that wasn't just seventeen years ago.

Speaker 1

Yes, because well, first of all, there's the cicadas that aren't periodical bruders. So they there are around every year, and they they don't do this behavior of waiting seventeen years. They have like a yearly reproductive cycle. But you may be saying, like, well, I've seen like mass emergence of cicadas and it hasn't been seventeen years since I've seen it, And that's because like they're they're on these different cycles. So this is not it's not that this event only

happens every second seventeen years. This brood X is only gonna happen every seventeen years because their population is on this schedule. But there are gonna be other staggered populations of cicadas that are on different schedules. Yeah, so we see these mass brewed emergence events every few years, and so it's yeah, so if you're like, uh, oh, I'm gonna miss this mass brood emergence, don't panic. There will be another one and you won't have to wait seventeen years.

But if you want to see this specific brute event, yeah, will have to wait another seventeen years. There's enough cicadas for everyone, don't worry. Speaking of which, actually apparently I read that cicadas tastes like canned asparagus really, which I don't know what, like the the like Vinn diagram of like people who have eaten cand asparagus and people who have eaten cicadas. Who has both eaten cand asparagus yuck and cicadas like, yeah, people have eaten both of them.

That they're like, oh, yeah, this is like the cand asparagus that I eat like what.

Speaker 2

Yeah, I mean liking asparagus is like a very specific thing anyway, Like I think asparagus is Okay, it's not my favorite. My sister loves it and she cooks it a lot, and you know, sometimes they'll eat it if she cooks it.

Speaker 3

But but yeah, but I've never had it canned.

Speaker 2

Yeah.

Speaker 1

No, no, I I'm like you, like, I'll have like roasted asparagus. I don't love it. It's a little too fibrous for me. Yeah, also making your piecemeal weird, I'm not Yeah, but like, but the but can't I couldn't like eat it. Something about cannix asparagus just does not peel to me at all. But then it's like, who's eat Like I well, actually, you know what, I guess it makes sense. The kind of person who would regularly eat cand asparagus probably would eat a cicada just out of curiosity.

Speaker 3

They're already eating eating weird stuff, so yeah, right, why not?

Speaker 1

Yeah, it's like, what, look, once you've stooped to the level of eating canned asparagus, why not just try a cicada?

Speaker 3

I'm thinking, is it like army rations or something?

Speaker 2

Because or like survivalists because I do feel like, yeah, because.

Speaker 3

That seems like like the kind of people who would do it.

Speaker 2

They'll be like, yeah, we eat bugs, We've also eaten you know, these canned vegetables.

Speaker 1

Yeah, of course, like bugs are going to be the meat of the future.

Speaker 2

Yeah, which I mean, like, yes, it grosses me out to think about, Like I I it both I both am like, oh, that's actually like a really good idea to like make cricket flower or something like that, because it's more readily available and it's you know, probably eat safer and maybe even than probably more humane than like factory farming and such.

Speaker 3

But right, but also like the idea gross.

Speaker 1

No, I'm with you, Like I'm like, yeah, no, we should be probably eating more insects that would be more ecologically good for the planet. Ah but yeah gross icky No.

Speaker 3

Yeah, yeah, I'm like I.

Speaker 1

I and I think it's entirely cultural. I don't think there's any real logic to it. There are places where people do eat insects and like it's totally normal and fine, and they probably like are they probably look at our food like they'd probably look at like a Carl's Junior like burger and be like, what the hell, Like, yeah.

Speaker 3

Exactly, No, it totally is cultural.

Speaker 2

And I feel like there's yeah and and people and you can like survive pretty well off of that.

Speaker 1

Yeah. But there's a Yeah, there's a guy that was accidentally got stranded I think somewhere in Australia, like in the desert brush area, and he survived by eating wichety grubs, which are these big like sort of you know how on The Lion King there's a scene where they like teach them to eat big grubs. It's they're huge grubs and they just look not super appealing to eat. But

people have been eat like for centuries. Uh, people have been eating the witchity grubs as as a part of like their diet, and they're they're perfectly good to eat. And this guy survived by eating them. Uh And yeah, I just it's it's totally cultural that we've we've been brainwashed to reject insects as food. Yeah, but somehow be okay with factory farming, which is a little messed up.

Speaker 3

Yeah, which is which is even grosser r.

Speaker 1

Right exactly, Yes, it's way gross I think.

Speaker 2

But like I don't like eating, Like I I eat meat. Sometimes I don't eat a lot of meat. But like, but like when I do, like, I don't like, I don't think I would like to eat a cricket if it looked like a cricket. Yeah, it could, But I also don't like to eat meat that looks like the animal that it is.

Speaker 3

Like I feel like yeah, and I feel like for me, that's a psychological thing, you know.

Speaker 1

I'm kind of the opposite. I almost like want to know I'm just eating a buz glad.

Speaker 3

Yeah.

Speaker 1

I feel like if it's if you're like this cookie was made out of ground up crickets, that's here, I've roasted this cricket and it's like prepared it, and you know, I'm like, Okay, at least this is being honest with me.

Speaker 3

That's true. I wouldn't want to be tricked into eating it or anything.

Speaker 1

Yeah, Yeah, I think I would rather. Also, I think I'd rather eat a prepared bug than I would to eat candasparagus. Absolutely, I'm not eating candasparagus.

Speaker 3

Yeah.

Speaker 1

I can't canned no or canned mushrooms too. I'd rather eat a freshly prepared insect. Yeah. In terms of the Cicada, the Cicada broodex, like, should we be concerned about this, like, are you in imminent danger of having your face covered in cicadas and then like you know, skeletonizing you. No, cicadas are harmless to humans. They don't sting or bite. They are allowed, So if you live near where this happening, you might have some tough nights, but you know, they're

not They don't hurt humans. They also don't hurt they don't really hurt the trees or crops or anything. They're not like locusts. They don't destroy crops. They will suck the juice out of tree twigs, which also doesn't really hurt the trees that much. Like it seems actually to just kind of like prune the trees. They don't really do lasting damage to the trees. There are even some arguments with that. Because they burst out these holes, it helps aerate the soil and is actually good for the trees.

I feel like it's probably a net neutral because they do suck some of the juices out of the roots, and when they lay their eggs they actually like kind of cut into the tree a little bit to like stuff the eggs in, so they're secure there. So I think it's probably just a neutral effect. On the trees. But I have seen some arguments that it's actually beneficial, so maybe. But either way, they're not harmful, So just enjoy the big cicada party that happens only once every seventeen years.

Speaker 2

They're kind of the musical theater kids of the insect world, which I mean I relate to as a musical theater kid. They're they're really annoying, but they're harmless.

Speaker 1

Yeah, exactly.

Speaker 2

Yeah, don't don't like, don't hate on them too much. Just let them do their thing, you know. Yeah, like like, you know, you can find them annoying, but they're just.

Speaker 1

You know, yeah, they might be cosplaying as vampires, but it's exactly like tomato juice.

Speaker 2

So yeah, they just want to hook up at the cast party. You know, they just want to hook up at the cast party. So let them have their little their party full of you know, massage trains and.

Speaker 1

And do you know, go back underground soon enough.

Speaker 2

Yeah, exactly exactly. They'll they'll grow out of it, you know, just as theater kids. Yeah, kind of kind of grow out of the Yeah that's what they are. Cicadas are the theater kids.

Speaker 1

Yeah, I'm sure theater kids are going to be okay with that comparison.

Speaker 3

Yeah, I'm okay with it. And I'm a theater kid.

Speaker 1

Yeah exactly. You're the president of theater kidd.

Speaker 3

Oh God.

Speaker 1

So we've talked about cicadas and their mass brooding events, but they are not the only animal that does this. Mar Are you familiar with sea turtle mass hatching events?

Speaker 3

No, I'm not, but please tell me because I love turtles.

Speaker 1

Yes, So, thousands of female sea turtles have this uncanny ability to emerge from the ocean all at once to lay their eggs at specific beaches. So there are all of Ridley's sea turtles are one such species who will emerge by the thousands to lay their eggs at select beaches, like, uh, there's a beach called O'steonal in Costa Rica, and they seem to specific select particular beaches to all come and

lay their eggs on mass. And because they're all coming at the same time to lay their eggs, that means the eggs will all hatch around the same time as well.

Speaker 3

Wow.

Speaker 1

And so when these eggs hatch, they'll come out because like they bury them in the sand and they have each one has a clutch of I think a couple dozen eggs, and then they'll all come out at the same time, and the hatchlings will instinctively go towards the ocean, possibly guided by light reflecting off of the water. Some of them, like they'll come out during night and like the moonlight reflecting off the water seems to be a

beacon for them. These turtles, even though there are so many of them, actually surprisingly few will reach adulthood because they're small and delicious, like little cinnamon buns, and so like, there are lots of scabs and predators who wait for these events. They know it's happening, and these are very tasty treats for them because they're so defenseless and there they don't they can't move that quickly, so when they emerge,

they have this very dangerous trek to the ocean. And so having this mass hatching event again gives you safety in numbers like you are, you know, you may not make it to the ocean, but like you're much have a much better chance if you're one of like thousands and thousands of individuals. Then if it's just you coming out, and then like a seagull's gonna immediately see you and

just snatch you up. So, yeah, these these mass turtle hatchings, they happen all over the world, but like often these populations of sea turtles prefer specific beaches, so they're often these events that that people wait for these turtles to hatch and watch them or like sometimes do that.

Speaker 3

Yeah, yeah, turtles.

Speaker 1

Yeah, it's it's quite something. I mean, the babies are so cute. It's hard though, because like you know, a lot of them aren't gonna make it so and you can't you shouldn't interfere. Sometimes there are rescue groups that will like h kind of try to help protect them from like poaching and stuff. So but yeah, I mean it is. It is quite something though. So you know, watching a video of just like thousands of these turtles just like kind of like ambling because they can't move

very well. Uh, they just kind of like use their little flippers to like kind of push themselves forward, and it's just.

Speaker 2

Like, yeah, I like the little patterns that they leave in the ground. Yeah, I'm looking at the little patterns they leave, and it it does look like they're just moving forward very very slowly, just pinching.

Speaker 3

It's very cute.

Speaker 1

I mean, they're hustling you can tell they're hustling as fast as they can. Unfortunately that's just not very fast. Yeah, but yeah, they really, they really try to gun it to the ocean, but they can they can only move so fast because they're these little, tiny, little, tiny like sand dollar size things, and they yeah, it's but yeah, you're right. The patterns they leave behind are quite beautiful. But you may have heard of these sea turtle mass hatchings,

but there are also mass river turtle hatchings. Yeah, in the Amazon rainforest. So in Brazil, on the Perus River in the Amazon Rainforest, tens of thousands of baby array turtles, also known as the giant South American river turtles will hatch and make their way to the river. So similar to the sea turtles, they are buried in the sand,

which keeps the eggs safe. Right, So if you're wondering, well, why don't they just lay them in the ocean or in the river, the eggs are gonna be just sitting ducks or sitting eggs for anything to eat, So burying them and the sand keeps them safe. And so once they hatch, that is when the real trouble starts.

Speaker 3

So they say, giant, how giant, are they.

Speaker 1

Yeah, So as adults the babies are small, obviously cute little babies, but as adults they get up to about two hundred pounds or ninety kilograms in weight. Those are the larger I think on average they don't reach that weight, but like those are some of the larger individuals, and their shells can grow to be over three feet longer over one meters long. So I think typically they're a little smaller, so more around like one hundred two hundred and fifty pounds and a little smaller shells, but they

can get quite big. They're also I think as adults very cute. They have these long necks, and they have these little piggy noses, like little little piggy snouts. And then they also often like algae will grow on their shells, so I think they're really cool. Sometimes they get like these mohawks of algae growing on them. They're they're really interesting looking, very cool. And then the babies are adorable,

but they face a very unfortunate odds. So in a protected area of the Peruse River, these turtles will hatch en mass. So in twenty twenty, ninety thousand baby turtles hatch just within a few days of each other. And if you think that's going to look like a huge pile of baby turtles, that is what it looks like.

Speaker 3

Wow.

Speaker 1

Unfortunately, even though there's just so many of them, you'd think like, well, god, there must be like huge numbers of these turtles. Unfortunately, only about one percent of them will reach adulthood. So it truly is just a law of large numbers. Like you want to make as many babies as you can because their odds are so slim, and you just want to make sure that some of them will make it to adulthood.

Speaker 3

What are their predators, do you know? I mean there's a lot.

Speaker 1

Of different Yeah, for the sea turtles, there are a lot of like birds are a big one, but there are also plenty of small sharks like in the ocean that are really good predators. What about the river ones and the river ones again, I mean, there are a lot of skin averaging birds that fresh water birds that will pray for them. And then I'm pretty sure, uh, I mean, there are a lot of big fish in these rivers that are would be happy enough to eat them.

There's also otters river otters I believe that live in the area.

Speaker 2

Oh yeah, river otters are scary, Like I like, I like otters, but river otters are scary.

Speaker 3

They're they're yeah, they're serious.

Speaker 1

They're serious. Like you you think of the cute little sea otters. No, yeah, river otters are huge. They're like almost as tall, like they're as an adult man, and they they're long, they have huge teeth. They can take on crocodiles. They can like literally take on on gators and crocodiles and hold their own. So they're serious business. But yeah, so that that is perhaps one of the cutest mass spawnings. But in terms of the biggest mass spawning,

you have to go to the Great Barrier Reef. Yeah, the Great Barrier Reef is home to the largest mass spawning events in the world of coral. So, I know, coral looks like a plant or a rock, but they are living animals, which is mind blowing. They just don't they don't look like they should be alive. They look like a you know, they look like set dressing.

Speaker 2

Yeah, my grandmother had a coral ring and it's weird to me now because I'm like that's almost like that's like closer to fur than.

Speaker 1

It is to like, you know, diamonds skeleton gems.

Speaker 3

Yeah, exactly, and it was a very pretty ring. But yeah, I think about it now and I'm like, oh, so weird that that was alive once.

Speaker 1

Yes, yes, and so coral are very much alive. They are Nigerians, which is the same philum as jellyfish and seeing enemies. So yeah, they're actually related to jellyfish and seeing enemies. They are often colonials, so that means they form these huge groups of many individual polyps. So a polyp is like just like one individual like you see if you see a big branching thing of coral, chance, are there like thousands of individual polyps or hundreds of

individual polyps like on this piece of coral. Yeah, so a polyp generally speaking for coral is like a sort of oval structure. For some coral they look more like sort of a long flower with a stem. Some of them are more squat, some of them look sort of like a flower bulb. Some of them look more like pine cone shaped. But it's this is a living it's got it's a living animal with like living tissue and it eats. They'll they'll filter feed and they like will

come out of this. These corals and like, uh, you know, use use their flowering organs to like catch prey and filter feed and just whatever is floating around. So, colonial polyps will often share sort of a base either formed by fibrous proteins or calcified materials. Uh, and so that will form these big, beautiful structures that you see in the barrier reef. There are two main types of coral.

There are soft corals and stony corals. Soft coral you may not even realize their coral because they look they don't look hard. They are visibly soft. They look sort of like a bunch of sea an enemies or flowers.

Speaker 3

Is that this?

Speaker 2

Oh yeah, you have a picture of yellow ones and yeah, they look like they look like those.

Speaker 3

Bottle brush tree you know. Yeah things. Yeah they look like spiny but they look soft.

Speaker 1

Yes, yes they are. They are softer. They don't generally have that like hard calcified skeletal structure. They're held together by jelly like tissues and they but they also do have some spiny structures that will support them.

Speaker 3

I was gonna say, do they feel soft to touch?

Speaker 1

Yeah, so part of them would feel soft to touch, But the part of them that is the sort of like base that's holding them together is going to be a little more firm, sort of like spiny, like like tree branches. Right, but yeah, like the definitely the polyps themselves is going to be softer but hard. Coral is to feel hard. So the stony coral is the stuff that you probably think of when you think of coral. They look like mineral, more like a mineral than an animal,

but they are alive. So there are a bunch of tiny polyps on stony coral skeletal structures. And like these polyps are, they're less sort of like flowery looking than soft corals. They're more a little more conical shaped, and they give like these stony corals a sort of harder, more rocky appearance.

Speaker 3

Right.

Speaker 1

And because often like these these polyps are very tiny, only like one to three millimeters, you can barely see each individual. It just looks like this rocky texture on like this coral. It doesn't look like there's a bunch of individuals. But if you zoom in, those little little

bumps are actually like living polyps. And if you ever I have a visual eight formara here, you guys can check out the show notes and and see pictures of this, but I actually found because like I mentioned, I'm actually at my parents' house right now and I found this in the bathroom as a decoration. It's actually a a coral skeleton. So this is uh the uh, this is a stony coral and this is the calcified hard base of the skeleton that would home a bunch of little polyps.

And I'm gonna hold it up. Oh yeah, so you can see each of these little like they look like little holes or little divots. I don't know how much detail you can get from the camera.

Speaker 3

It was like little stars on it, Like they're not they're like little stars.

Speaker 1

Right, because that the little time like that was home to each of these polyps that had this like radial sort of branching structure. So each of those little like like feathery kind of star structures is where that that little polyp would have grown and have that like radial symmetry like a sea an enemy or like a jellyfish. But it was like a little individ and of course all that's left now is the hard calcified structure or

the skeleton. So if you have decorative coral, that is a skeleton that you have basically, yeah, I think.

Speaker 2

We used to have I like because when you when I as soon as I saw that, I was like, that looks familiar. And I feel like we might have had that in my bathroom when we were little.

Speaker 1

Or like it's a common bathroom decoration, yeah, or like like on on in like a little display on top of the back, when we had like you had like the TV cabinet.

Speaker 3

Yeah, I feel like we had we had like.

Speaker 2

We had like potpourrie on one part of it, and we have but we had like pretty rocks and coral on there too, yeah, or maybe like my grandparents had it. Yeah, I feel like that was that was a very kind of seventies eighties decoration exactly.

Speaker 1

Yeah. Yeah. And so it's it was kind of fun neat because I was like thinking about this episode and like and I was just like, you know, doing my business in the bathroom. We don't need to go in detail there. But I saw this like on a shelf, and it's like, oh, hey, yeah, That's what I'm talking about today.

Speaker 3

Yeah.

Speaker 1

Yeah. So, because corals are often huge colonies with hundreds of thousands of individual polyps, and the Great Barrier Reef is one of the world's largest coral systems with over six hundred distinct coral species. There are millions and millions of individual polyps in the Great Barrier Reef by my rough calculation. When it is a coral species time to spawn, it gets buck wild in the ocean. So coral are sessile,

which is just a way of saying they're immobile. They spend their whole time just kind of staying still, you know, just like we've been on quarantine. We've been sessile on our couches. And so having sex is a problem because how do you have sex and reproduce when you can't really move. So they will release sperm and egg packets into the water, and if these sperm and egg packets just happen to bonk into each other, they will fertilize

and form an embryo. So in order to maximize the chance of successful fertilization, they have to synchronize because like if you just like send out your egg or your sperm packet and then it's like nobody else is doing it, maybe one person like way far away is doing it, the chances are going to bunk into each other is like pretty minimal if everyone's doing it. It's a blizzard of sperm and egg packets, and the chance that you're going to bunk into something and get it fertilized is

very high, and so that's what they do. It's this blizzard of coral sperm and eggs, and it's super colorful. So uh, like coral, as you know, are very pretty, very colorful, and so you wouldn't even guess that it's such a such dirty business going on here because it comes in these colors of like yellows and pinks. Uh, and it's like this flurry. Uh, it looks like a magical enchanted blizzard, but you know that's a it's coral sex junk happening.

Speaker 3

Yeah.

Speaker 2

There's a photo that I'm looking at here where there's like there's like coral spawning and it looks it's like like it's like really beautiful. You could put it up as like a photograph like in your home as as a decoration. And then there's another one and there's a diver in the middle of it and he looks a little like, Okay, what did I get in the middle of here?

Speaker 1

Y'es? Oh? Oh you guys, yeah, guys, just come on. Yeah, yeah, it's like it's like a snow globe. Like you turn in the snow globe and you see all these like big sort of like things of snow, except like it's pink and yellow and it's you know, coral sex goo. Yeah,

once they fertilize, says, we'll create new coral polyps. You can actually look like there's an aerial photo too, like that shows these like mass coral embryos that creates like this pink film on the ocean and look like someone just like spilled a bunch of pink ink in the oation. It's beautiful. Uh, it's just but it also like shows you the scale of this event. It's just huge, huge number of uh any coral just making babies.

Speaker 3

And how often does this happen?

Speaker 1

I think this is a yearly event. I'm not sure if like every species does it every year, but they like it's staggered enough that this happens relatively often. So

should we be worried about this? Not really? I mean unless you are a fish in a lagoon during an unfortunately timed weather storm that causes coral sex goop to rain down in your home and literally suffocate you, which actually happened nine years ago in a lagoon and an atoll in the Cocos Island in the Indian Ocean, a fluke storm blew a bunch of coral spawn into a lagoon system, which consumed oxygen, and then the decaying coral

polyps released methane, which made the water unbreathable by the fish, who suffocated and died on mass. So sometimes, hey, coral sex does kill.

Speaker 3

Wow.

Speaker 2

Yeah, that's like getting caught up in like somebody else's drama.

Speaker 3

Oh jeez, yeah.

Speaker 1

Yeah, yeah, someone like it shows you a text, like between them and someone they're singing, and it's like they expect you to resolve the drama. It's like, no, yeah, I'm not going to be a fish in your coral right.

Speaker 3

That's a great way to tell them. Now, I'm not fish in your coral sex lagoon. Okay, they'll know what you mean you, they'll know, they'll know they should If they don't, you don't want to be their friend.

Speaker 1

Anyway, exactly exactly. I mean, like if they're if they're making you be a fish in their coral sex agon, that's to get out of there. You got those toxic ties. Yeah. Well, I think we've covered probably as many mass spawning events as I can tolerate in one episode. But yeah, it's it's a it's look, it's the beautiful cycle of life which sometimes happens. And buy the millions. But before we go, I do want to do a listener email that was in response to last week's episode, which is about bunnies.

Mar you missed the bunnies, miss the bunnies by one by one week, so instead you had the mass cicada sex episode.

Speaker 2

I mean, it's it's still interesting to me and I and I got turtles, which I like.

Speaker 3

So that's true. That's true too.

Speaker 1

Massive baby turtles. Yes, a lot of them are gonna die, but hey, it's.

Speaker 3

But they're cute while they last. Yeah, it's it's an ephemeral thing.

Speaker 1

Yeah, yeah, you know, yeah, enjoy, enjoy the turtles every moment. Don't think about the turtles of the future, think about the baby turtles of the now.

Speaker 2

Yeah, it's it's like that those those you know what are those like the mandalas that they'll make in sand?

Speaker 3

Yeah, think about think about the beautiful patterns that the turtles making sand and.

Speaker 1

Yeah, and enjoy and yeah yeah, yeah that's that's you know, so it goes, yeah, well, here is this very nice, uh not deadly email. Hi Katie, I'm a longtime listener and I really enjoyed your lagomorph episode. I am a bunny owner and an ecologist and really appreciated the love you give to these underappreciated fluff balls. I just wanted to tell you a few cool things that I've learned

about pet domestic rabbits. First, they can be letterbox trained fairly easily and successfully, especially if they're a spade or neutered. I think in the show I threw a little bit of shade at bunnies. I said that you can try to litter box train them, but I think it's sort of on whether they want, whether they feel like it or not. Yeah, but apparently it's look Maya Kolpa. Apparently bunnies will fairly readily poop in a litter box. That's good to know.

Speaker 2

They seem very stubborn domestic. Every domestic bunny I've met has has been like I have a mind of mind.

Speaker 3

Like people think cats are hard to control. Bunnies yeah, yeah.

Speaker 1

Oh but yeah, but it's a whole new Like cats are sort of like a little bit but they're they're coy and playful about it, where they're like, oh maybe will I won't I but they do. They do love you and they but like bunnies. Yeah, they're like, no, no, you think you're gonna get me to do something? Uh uh yeah, I'll kick you in the face and pee

on you. Yes, exact exactly. Although although the listener does admit that there will be an occasional misplaced bunny poop, so hey yeah, she writes that the secret is to put hay in or next to the litter box so they can eat while they poop or pete luxury luxurious living. Once litter trained, the bunnies can roam in an area of the house freely after some bunny proofing. The House Rabbit Society has lots of information on how to do this. I also just wanted to mention a few other super

cute bunny behaviors. When they are very excited, bunnies will do a jump and a shake their bodi's mid air, which is called a binkie, And when they are very relaxed, they will dramatically flop over on their side.

Speaker 3

Wow, so cute.

Speaker 1

I actually had a cat named Binkie and he was he was pretty rabbit like because he was very scared. He never killed anything and would run away. And one time, this is in high school, and I came home and I was, you know, frustrated with school, so drop my books on the floor and across the room. I didn't realize the cat was there, and so he jumped like a like three meters into the areas. It's so funny,

poor thing. And then then the listener shared some beautiful pictures of the bunnies which are just for me, So sorry about that. But oh and then and then she writes, I also especially appreciated your bee episode. I did my master's degree studying native bees in Ontario, so I appreciate it when bee species other than honey bees get a mention. And this is from Emma. Thank you so much, Emma for your kind words and for your bunny facts. So

I take it back. Bunnies can be litterbox trained, but again, hey, look when they want to, like if they there may be a poop once in a while, You're just gonna have to deal with it, right.

Speaker 3

Don't pretend like you can control the bunnies.

Speaker 1

No, you can't control a bunny.

Speaker 3

Control the bunnies no, no, they are.

Speaker 1

They are those strong back legs they can they can slap you.

Speaker 3

Yeah.

Speaker 2

I have a friend who has bunnies, and she says that they they when they're pissed off at you, they'll turn their back on you and kick with their back legs.

Speaker 3

They'll kick you. Yeah.

Speaker 1

Yeah, which, which.

Speaker 3

I love you is is I love that about them.

Speaker 2

It's just like I love you bunnies for being for being like they hey, screw you with their back legs.

Speaker 1

Yeah. I mean I like that they stand up for themselves because like we have the sense of like, oh, they're just a little floppy bunnies. They don't they're helpless frightened rabbits. Yeah yeah, no, I mean it's more like the Peter Rabbit level of like defiance.

Speaker 3

They Yeah. My sister was bitten by a bunny once oof.

Speaker 1

Yeah.

Speaker 3

Yeah.

Speaker 1

They got strong teeth, they do.

Speaker 3

Yeah. She said she had to get a Titanish shot after oof.

Speaker 1

Yeah, because oh yeah, because their teeth are so long.

Speaker 3

Yeah.

Speaker 1

Wow.

Speaker 3

She said the shot hurt more than the bite, but it was still very very strange.

Speaker 1

But I mean, basically the bunny is responsible for the shot too, exactly. Insult and injury to injury. Yeah, yeah, no, bunny is a serious Like I know, bunnies are cute. I don't necessarily discourage having bunnies as a pet, but if you want one, definitely look into it because I would say they are one of the harder pets, Like they're harder than a cat or a dog. Yeah, I would say, so, yeah, just just check it out because because there's a lot of special care you have to do.

Uh My, I had a friend who had a bunny and again, like I would pet it and then when it wanted me to stop, it would kick me and pee on me like it was a mail And I think they like to flick urine, so they so he would kick me and flick you on me. And I was like, you know, I think I'll stick with cats and dogs.

Speaker 2

Yeah, you can predict they're more productive.

Speaker 1

I only sometimes get kicked by my dog, and that's usually on Yeah, my.

Speaker 2

Cat will will you know, they'll go away or maybe they'll hit me or bite me lightly if I'm annoying them.

Speaker 3

Yeah, I'm like, okay, all right, we'll stop petting you.

Speaker 1

Yeah. Yeah. My dog loves belly rubs, but like once it's like she's got a very specific. You have to pet her very specifically, and if you stop, like she she looks so sweet and angelic. But then if you pet her wrong, like suddenly the little Chihuahua demon face comes into play and it's oh my god, she's like, it's really funny. Satan takes over. Yeah.

Speaker 1

I mean, if they if if you're like in a lagoon and they foist their kink upon you in the that's a yeah, but it is problematic.

Speaker 3

You were wandering into their space.

Speaker 1

Yes, but that was like that. I just there's like a freak storm that dispensed all of this coral sexcw on these poor fish. It's like it's like the like a disaster movie, except a lot of corel coral eggs and sperm. Attack of the killer coral, attack of the killer coral coral baby's attack sounds like there might be a plane, Yeah there is? Or is it a storm of coral stuff?

Speaker 3

We've angered the coral. We've angered the coral guards. Gods.
