The pygmy killer whale (Feresa attenuata) is a poorly known and rarely seen oceanic dolphin.[3] It is the only species in the genus Feresa. It derives its common name from sharing some physical characteristics with the orca also known as the killer whale. It is the smallest cetacean species that has the word "whale" in its common name.[4] Although the species has been known to be extremely aggressive in captivity, this aggressive behavior has not been observed in the wild.[5]

The species had been described by John Gray in 1874, based on two skulls identified in 1827 and 1874. The next recorded sighting was in 1952 which led to its formal naming by Japanese cetologist Munesato Yamada in 1954.[6]
