The Arctic Ocean is the home of three major groups of mammals that depend on the sea for survival and show varying degrees of adaptation for maritime life. Most fully adapted are the whales (Cetacea), which never leave the water, and the seals and walruses (Pinnipedia) that feed entirely at sea but emerge onto land or ice for pupping and basking. Less exclusively marine are two species of the order Carnivora—Polar Bears ( Ursus maritimus ), that seldom live far from the sea because they feed almost entirely upon seals, and Arctic Foxes ( Alopex lagopus ), some of which move out onto the sea ice during the winter, mainly to scavenge on the remains of seals killed by Polar Bears
