Large animals, such as penguins, seals and whales, have a thick layer of fat called blubber under their skins. This fat layer acts as an insulator to keep theses animals warm. Fish, such as the naked dragon and the Antarctic cod, survive in the cold waters of Antarctica because of a special substance inside their blood called glycopeptide. This substance acts much like antifreeze. Antifreeze added to the water in a car's radiator keeps the water from turning to ice just as glycopeptide keeps the blood of these Antarctic fish from freezing.
Antarctic animals live along the coast of the continent.
In some areas, such as the Antarctic penusula, the temperatures get above freezing. Most likely other animals would eat the dead carcass, but if not eaten it could rot in the warm summer temperatures. In colder areas of the continent where the temperatures do not get above freezing, carcasses of seals have been found in the ice that are hundreds of years old. Dogs are no longer allowed on the continent. It seems that most of the time, they attach transmitters or actual cameras to the animals, and track the animals for as long as they can, until the transmitter falls off.
