Life Beneath the Antarctic Ice
In Life Beneath the Antarctic Ice, learn how the world's largest desert doubles in size during winter, creating a vast, frozen expanse. Beneath the ice lies a surprisingly stable environment, allowing life to evolve and thrive in extraordinary ways. This video is excerpted from BBC’s Seven Worlds, One Planet, a series featuring remarkable animal behavior from all seven continents.
Lesson Express
Q: How do the colder temperatures of winter transform the continent of Antarctica?
A: So much of the ocean around the continent freezes that the continent doubles in size.
Q: Why is it so diverse under the ice?
A: The environment below the ice is stable and has allowed life to diversify over thousands of years.
Q: How does being a hermaphrodite help the nudibranchs to reproduce?
A: The nudibranchs have trouble finding a partner with their small eyes, so it helps that they don’t have to find a particular gender.
