How do over 8,000 species thrive in the freezing waters of Antarctica?

How you survive the coldest place on Earth - Nadia Frontier · 4:29 · Video: TED-Ed · Watch at the source

In short: Beneath the vast Antarctic ice lies a surprisingly diverse ecosystem. This video explores the specialized biological traits that allow thousands of marine species to survive and flourish in one of the planet's most extreme environments.

Antarctica is defined by a massive surface area spanning more than 3 million square kilometers. While the surface is harsh and frozen, the coastal waters just meters below the ice host a thriving community of more than 8,000 distinct marine species.

These creatures have evolved an arsenal of otherworldly adaptations to manage the frigid temperatures. The video investigates the specific mechanisms that enable this high level of biodiversity to persist in such a demanding, sub-zero habitat.
