Pinnipeds (from Latin pinna "wing or fin" and ped- "foot"), or fin-footed mammals, are a widely distributed and diverse group of semi-aquatic marine mammals. Seals, sea lions, and walruses are well-known examples of pinnipeds. In addition to inspiring the names for many sports teams (such as the three sports teams in the San Francisco, California area known as "the Seals"), pinnipeds have also inspired a number of fictional characters, creatures, and entities across human culture and media.
