Recorded MS
Pinnipeds, Polar Bears, and Playful Otters

You see them in zoos and aquariums, now learn more about the animals who live on the edge of the oceans. Unlike terrestrial mammals, and unlike cetaceans who spend their whole lives in the seas, these three groups are adapted to life on the edge of the water, an amphibious existence both fruitful and dangerous. Join for a fun, deep dive into science!
