How do seals survive in Antarctica?

Seals survive the cold temperatures of Antarctica by having a protective layer of blubber that helps to store energy and heat. The seals of Antarctica are also safe from most predators, but do have to watch out for polar bears and other seals that may pose a predatory threat.

There are only four types of seals in Antarctica and they all spend much time in the water hunting for food. The crabeater seal lives on ice floes where it is safe from the predatory leopard seal. The Weddell seal spends most of its time under water, being able to submerge for over an hour, resting on ice floes or emerging to give birth. As long as a seal remains healthy, the cold temperatures do not affect its health.
