The '''Walrus''' ''Odobenus rosmarus'' is a large species of [[Arctic]] pinniped, readily distinguished from all other marine mammals by the possession of a pair of substantial tusks, used for hauling them onto ice floes. Walruses have no external ears, and are heavily whiskered, which aids them in detecting their main food, [[mollusc]]s living on the sea floor. Sometimes rogue walruses, generally large adult males, will attack and consume smaller [[seal]]s and toothed [[whale]]s.
