Pilot whales are cetaceans belonging to the genus Globicephala. The two extant species are the long-finned pilot whale ( G. melas) and the short-finned pilot whale ( G. macrorhynchus ). The two are not readily distinguishable at sea, and analysis of the skulls is the best way to distinguish between the species.

The name for the genus, "Globicephala" is derived from a combination of Latin globus ("globe") and Greek kephale ("head"). The specific name "melas" is Greek for "black". This species has also earned the nickname of "pothead whale ...
