Winter Underwater With Weddell Seals
In Winter Underwater With Weddell Seals, narrator Sir David Attenborough explains how Weddell seals spend the winter underwater where the 28°F (-2°C) water is warm compared with the frigid temperatures above. Watch the Weddell seal glide through a watery world that has not changed for millions of years. This video is excerpted from BBC’s Frozen Planet, a series that shows a fragile world of beauty and hostility, where nature finds a way to survive and thrive in frigid conditions.

A: Students may talk about how the seals are able to escape the wind and some of the cold by being underwater. Seals have to keep scraping the ice to keep holes open so they can breathe.
Q: How does the Antarctic water temperature compare with the air temperature? Which is warmer?
A: The water is warmer (comparatively).
Q: How has the seal adapted to living in the water during the winter?
A: The seal has wide jaws that it uses to scrape ice away and keep a breathing hole open.
