The dwarf sperm whale (Kogia sima, formerly Kogia simus) is one of three extant species in the sperm whale family. They are not often sighted at sea, and most extant information comes from the study of stranded carcasses. Today, the dwarf sperm whale is generally classified as one of two species, along with the pygmy sperm whale, in the family Kogiidae and genus Kogia. The two species were not regarded as separate until 1966. Most taxonomists regard the family Kogiidae as belonging to the superfamily Physeteroidea, though some consider this taxon to be a subfamily (Kogiinae) of the family Physeteridae. Order: Artiodactyla, Infraorder: Cetacea, Family: Kogiidae, Subfamily: Kogiinae, Genus: Kogia, Species: Kogia sima Owen, 1866.
