Heaviside's dolphin is a small dolphin up to 1.8 meters long that lives in cold coastal waters off the shores of South Africa and Namibia. It has a dark back, light belly, and short beak.
Heaviside's dolphin differs from related species by its small size, short beak, and distinctive light pattern on the sides. It is important for marine nature because it regulates fish populations and serves as prey for large predators.
