All mammals have some hair, but cetaceans, sirenians, elephants, domestic pigs, naked mole rats, hippopotamuses, rhinoceroses, walruses, sea lions, some seals, and others lack dense, inslulating body hair. Humans' body hair is not very dense either. Thus, hair is a characteristic of mammals, but dense hair covering the entire body is not.
