Pinnipeds are typically sleek-bodied and barrel-shaped. Their bodies are well adapted to the aquatic habitat where they spend most of their lives. Pinnipeds have flippers for hands, big bulky bodies, doggish faces, and big eyes. Unlike cetaceans, pinnipeds have their noses on their face, and each nostril of the nose closes when the pinniped goes under water. The word pinnipedia translates from Latin as "feather or fin foot," referring to their often large fin-like flippers. All pinnipeds must come ashore to breed, give birth, and nurse their young. seals, sea lions, and walruses are taxonomically related to other carnivores, including bears, dogs, raccoons, and weasels (including otters).
