Hardcore Natural History Series - Sea Otters: A Parasite's New Host

Despite southern sea otter population growth since 1911, otters are faced with increasing challenges to their survival. One of the largest obstacles they face is a disease caused by the thorny-headed worm, a parasite known by scientists as an acanthocephalan. Since the 1960s, species of this parasite, normally found in sea birds, have increased dramatically in prevalence in otters, resulting in more otters dying from infection. In his talk, Richard Grewelle, PhD candidate at Hopkins Marine Station, discusses his research, which takes him from otters to sea birds to crabs in an ecosystem-level adventure to understand the thorny-headed worm's world.
