Pygmy killer whale

The pygmy killer whale (Feresa attenuata) is a poorly known and rarely seen oceanic dolphin, the only species in its genus, named for a resemblance to the orca despite being the smallest cetacean species to carry the word whale in its common name. Adults average just over 2 meters in length, with males maturing at about that size, and are dark gray to black on the back with a sharp break to lighter gray on the sides, white around the lips and snout, pinkish white skin near the genital area, rounded dorsal fins and roughly 48 teeth split between the jaws. It is found in tropical and subtropical waters worldwide, generally in deep water 500 to 2,000 meters, with regular sightings off Hawaii and Japan and records from the Indian, Atlantic and Pacific Oceans.
