Although dolphins have blubber instead of fur that help hold in its heat and give it a streamline shape, it is true that dolphins do have hair, but only a tiny bit. The only place that they have hair is right next to their blowhole. Though most dolphins do not have hair, they do have hair follicles. These hair follicles are believed to perform some sort of sensory function. For instance, the small hairs found on the Boto river dolphin are believed to function as a tactile sense possibly to compensate for the creature’s poor eyesight.
