Walrus

The walrus (Odobenus rosmarus) is a large pinniped species found in the Arctic circle and is the only extant member of the family, Odobenidae, and the only species in the genus, Odobenus. Two subspecies are recognized, the Atlantic walrus (O. r. rosmarus), and the Pacific walrus (O. r. divergens). Walruses are described by their tusks and whiskers and their considerable bulk. They are the third largest and heaviest species of pinniped, only being both species of elephant seals.
