The pygmy killer whale (Feresa attenuata) is a poorly known and rarely seen oceanic dolphin. It derives its common name from sharing some physical characteristics with the killer whale. It is the smallest species that has "whale" in its common name. Although the species has been known to be extremely aggressive in captivity, this aggressive behavior has not been observed in the wild. Order: Artiodactyla, Infraorder: Cetacea, Family: Delphinidae, Genus: Feresa, Species: Feresa attenuata (Gray, 1874).
