Santa Cruz Naturalist
How do elephant seals sleep? Part 2

We follow up with Jessie Kendall-Bar, a Ph.D. student at UC Santa Cruz in the Ecology & Evolutionary biology department. Last month, she told us about her research focusing on the neurophysiology of sleep in marine mammals, specializing in elephant seals. This week on Santa Cruz Naturalist, she tells us more about how elephant seals sleep on their long migrations.

Elephant seals sleep manage to sleep underwater, at depths of around 200 meters! For how long you wonder? Listen to find out more.
