Seals are aquatic mammals. Great hunters of the oceans of the world, they are social, agile, and quite intelligent.
This category of wildlife includes all sorts of finned, aquatic mammals, and their relatives, including seals, sea lions, and walruses.
Seals are often hunted for their furs, which are quite valuable in many markets. Their blubber and oil may also fetch high prices. Their intelligence also means that they take well to being trained, and may serve as animal companions.
Walruses are an unusual member of the seal family with long, curving tusks, often used to help keep air holes in ice-chocked seas during the winter. They are quite large, and quite a bit wilder than their smaller cousins. The ivory from walrus tusks can be quite valuable.
