Pilot whales' long, sickle-shaped flippers and tail stocks are flattened from side to side. [4] Male long-finned pilot whales develop more circular melons than females, [4] although this does not seem to be the case for short-finned pilot whales off the Pacific coast of Japan.

Though mass strandings of this species are most common in New Zealand, pilot whales have beached themselves in many other countries in places such as northern Europe, the Atlantic coast of North America, South America, and southern parts of Africa. Over 600 pilot whales were involved in a stranding at Farewell Spit, New Zealand on February 9, 2017.
The name "pilot whale" originated with an early theory that pods were "piloted" by a leader. Other common names include the "pothead whale" (after the bulbous melon), and "blackfish" (a catch-all term used to designate numerous species of small, dark-colored toothed whales, including the pygmy sperm whale and false killer whale).
Articles relating to the Globicephala (pilot whales). 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 sei whale, or Rudolph's whale (Balaenoptera borealis), lives mainly in the North Atlantic and avoids enclosed seas, [22] but occasionally makes occasional incursions into the Mediterranean, although this is considered exceptional [12] and restricted to Spain and France. [14] The sei whale is classified as "endangered" on the IUCN Red List. [23]
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.
Globicephalinae is a subfamily of oceanic dolphins that includes the pilot whales (Globicephala spp.), the pygmy killer whale (Feresa attenuata), the rough-toothed dolphin (Steno bredanensis), the false killer whale (Pseudorca crassidens), the melon-headed whale (Peponocephala electra), Risso's dolphin (Grampus griseus), and the snubfin dolphins (Orcaella spp.).
Risso's dolphin (Grampus griseus) is a marine mammal and dolphin, the only species of the genus Grampus.Some of the most closely related species to these dolphins include: pilot whales (Globicephala spp.), pygmy killer whales (Feresa attenuata), melon-headed whales (Peponocephala electra), and false killer whales (Pseudorca crassidens).
