Episode description

The impact of the avian flu of elephant seals resulted in the death of 17,000 individuals in a population in Argentina. Researchers think the marine mammals caught the virus from migrating birds near their haul out areas that are usually packed with the animals one on top of the other. Unfortunately, 97% of the elephant seal pups were lost resulting in a devastating loss for generations to come. 

In this episode of the "How to Protect the Ocean" podcast, host Andrew Lewin discusses the devastating impact of the H5N1 avian flu on the elephant seal population off the coast of Argentina. Over 17,000 elephant seals died last year due to the outbreak, with approximately 97% of the pups affected. This significant loss poses a serious threat to the population's future, as elephant seals are a slow-growing species that take time to reach sexual maturity and reproduce.

The episode highlights how the H5N1 virus has adapted to marine mammals, allowing it to spread efficiently and evolve into distinct strains. The decline in the seal population and the loss of genetic diversity could make them more susceptible to future outbreaks and environmental stressors. The host emphasizes the importance of ongoing research, monitoring, and conservation efforts to mitigate risks and support the recovery of the elephant seal population.

Lewin expresses concern over the emotional toll of witnessing such a high mortality rate among the pups, which are crucial for the colony's future. He calls for increased funding and prioritization of conservation efforts to ensure the survival of this vulnerable species. The episode concludes with a commitment to follow the story and seek ways to help the elephant seals as a community.
