How does the wildlife in Antarctica keep warm?
Kris, Holland Large animals, such as whales, seals and penguins, have a thick layer of fat called blubber under their skins. This fat layer acts as an insulator to keep these 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.
