Weddell seals have developed many different fascinating adaptations for living and thriving in the cold icy environment of Antarctica. For example, they have evolved large strong sharp front teeth to use to rake the sea ice to enlarge and keep holes and cracks open so they can breath and access the surface of the sea ice. They also have developed the ability to hold their breath for over an hour to make long dives beneath the Antarctic sea ice.
These seals also have a special secret to getting around when they're on top of the sea ice! Here's the Weddell Seal Population Project's latest short-short video produced by Jeremy Schmidt that shows us how it's done!
