Long-finned and short-finned Pilot Whale or Globiocephala macrorhyncus are so similar, it is difficult to tell the two species apart. They were traditionally differentiated by the length of the pectoral flippers relative to total body length and the number of teeth.
The long finned Pilot Whale was thought to have 9 to 12 teeth in each row and flippers one-fifth of total body length, compared to the short-finned Pilot Whale with its 7 to 9 teeth in each row and flippers one sixth of total body length.
Studies of whales in the Atlantic showed much overlap in these characteristics between the species, making them clines instead of distinctive features. Thus, biologists have since used skull differences to distinguish the two species.
The skull of the short finned Pilot Whale has a shorter and broader rostum with a premaxilla that covers more of the maxilla. By contrast, the long finned Pilot Whale’s skull has a more elongated rostum and a more exposed maxilla.
On average, Pilot Whale or Globiocephala macrorhyncus only have 40 to48 teeth, about one third the amount seen in other dolphins.
