Short-finned Pilot Whale (Globicephala macrorhyncus) is a member of the dolphin family and are also known as Black Fish. The Black fish family (named from their black skin color) also includes Killer Whale (Orcinus orca), False Killer Whale (Pseudorca crassidens), Pigmy Killer Whale (Feresa attenuata) and Melon-headed Whale (Peponocephala electra). Pilot whales are so named because it was once believed that each observed group was navigated by a pilot or leader. Their Latin name, Globicephala, means “round head”, which is one of the main identifying characteristic of the species.
