“Pilot whales are cetaceans belonging to the genus Globicephala. There are two extant species, the long-finned pilot whale (G. melas) and the short-finned pilot whale (G. macrorhynchus). The two are not readily distinguished at sea and analysis of the skulls is the best way to tell the difference between the two species. Between the two species, pilot whales range in waters nearly worldwide with long-finned pilot whales living in cooler waters and short-finned pilot whales living in warmer waters. Pilot whales are among the largest of the oceanic dolphins, exceeded in size only by the killer whale. They and other large members of the dolphin family are also known as blackfish”. – Wikipedia
