The few animals that live on the mainland are birds such as Antarctic terns, grey-headed albatross, imperial shag, snowy sheathbill and the most well known inhabitant of Antarctica, penguins.
Most Antarctic predators are found in the polar waters, including the orca and the leopard seal.
Normally when colder conditions arrive, animals go into a state of suspended animation called hibernation, when they go into a state of inactivity for long periods of time, which they do not come out of until more suitable conditions for them to survive in arrive.
Some aquatic mammals, such as walrus, seal, sea lion, narwhals, beluga whales and killer whales, can store fat called blubber that they use to help keep warm in the icy waters.
Other mammals such as the musk oxen can keep warm by growing long, shaggy fur to help insulate heat.
