Why Don’t Fish Freeze in Antarctica?

Journey to Antarctica in a new digital series from NOVA and PBS Digital Studios, and discover what it takes to do science in Earth's most remote natural laboratory. Hosts Caitlin Saks and Arlo Pérez set up shop at the largest research base in Antarctica and embed with scientists and support staff alike to find out what it’s like to live, work and do science on our southernmost continent.

Why Don’t Fish Freeze in Antarctica?

Season 1 Episode 7 | 12m 1s | CC

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?
