How is it possible that an animal, any animal, can survive the dead of an Antarctic winter? No food, no shelter; just ice, cold, and wind for more than a hundred days straight. But that’s exactly what emperor penguins (Aptenodytes forsteri) do—not only surviving, but breeding in one of Earth’s most inhospitable environments.

To the casual observer, the birds appear to just stand around on the ice and endure their frigid world. A longer look, though, reveals that penguins often form tight groups, especially when temperatures plummet. This “penguin huddle” appears to be at the core of the birds’ ability to conserve body heat and survive outside temperatures that would kill most other creatures. But exactly how these huddles function and how they subtly change in shape over time to benefit all members of the group has remained a mystery.

The time lapse video of this phenomenon is fascinating.
