The Benguela dolphin (Cephalorhynchus heavisidii), more commonly known as the Heaviside's dolphin, is one of the four members of the Cephalorhynchus genus of dolphins. They are usually found in coastal waters in small groups. These dolphins are always on the move in search of food in their small habitat range as they are a non-migratory species.

Heaviside's dolphins are social, friendly, and curious animals that will approach humans or boats in an effort to get a better look. These dolphins are fast swimmers as they perform acrobatics in the water as a form of play.
