The classification of the hump-backed dolphins is still in dispute, however, most authorities currently accept only 2 species (the Atlantic Hump-Backed dolphin and the Indo-Pacific Hump-Backed dolphin). Confusion is most likely with the bottlenose dolphin, but with an elongated hump of fatty tissue in the middle of its back and a relatively smaller dorsal fin, the Atlantic Hump-backed Dolphin is fairly easy to recognize.
