Pinnipeds, including true seals, walruses and sea lions and fur seals, are a widely distributed and diverse clade of semiaquatic, mostly marine mammals of the order Carnivora. There are 34 living species. They have streamlined bodies and four limbs that have evolved into flippers. Males typically mate with more than one female, and the females raise the pups, often born in the spring and summer months. Pinnipeds generally prefer colder waters and spend most of their time in the water, but come ashore to mate, give birth, molt or escape from predators such as sharks and orcas. Humans have hunted seals since at least the Stone Age, and commercial sealing had a devastating effect on some species from the introduction of firearms through the 1960s. Populations have also been reduced or displaced by accidental trapping and marine pollution. All pinniped species are now afforded some protections under international law.
