A marine mammal of either of the genera Arctocephalus or Callorhinus of the eared seal family Otariidae. They differ from the true seals by having small, visible ears and the ability to walk on land
Any of several eared seals of the genera Callorhinus or Arctocephalus, having thick, soft underfur that is valued commercially for use in making garments. Any of nine species of eared seals valued for their fur, especially the chestnut-coloured underfur. Fur seals live in groups and feed on fish and other animals. They were driven nearly to extinction by fur hunters, and most species are now protected by law. The northern fur seal (Callorhinus ursinus) is a migratory inhabitant of northern seas. The male is deep brown, has a grayish mane, grows to about 10 ft (3 m) long, and weighs about 650 lb (300 kg). The dark gray female is much smaller. The eight species of southern fur seals (genus Arctocephalus) occur in the Southern Hemisphere and on Guadalupe Island, Mex. They are brown or black and average 4-6 ft (1.2-1.8 m) long
