Why Don’t Fish Freeze in Antarctica?
Season 1
Episode 7
Arlo and Caitlin learn that the Antarctic marine realm is not only spectacular to see, but fascinating for scientists to study. The water is so cold that fish inhabiting it should freeze like an icicle. So how do Antarctica’s fish, which penguins and seals rely on for food, survive in waters below their freezing point?
