Bottlenose Dolphins are countershaded; that is to say that their ventral (stomach) side is a different color than their dorsal (back) side, for camouflaging purposes. While there are believed to be two species of bottlenoses and two subspecies of one of these (essentially making three total), they are all gray in color. Due to the aforementioned countershading, they are generally dark gray on top near their dorsal fin while they are very light gray to almost white along their underside.
