The Atlantic Spotted Dolphin (Stenella frontalis) is a dolphin found in the Gulf Stream of the North Atlantic ocean. Older members of the species have a very distinctive spotted coloration all over their body. The coloring of the Atlantic Spotted Dolphin varies enormously as they grow. Calves are a fairly uniform grey color. When the calves are weaned, they then begin to get their spots. Juveniles have some dark spots on their belly, and white spots of their flanks. Their back and dorsal fin are a darker grey than the rest of the body. As the animal matures the spots became denser and spread until the body appears black with white spots at full maturation.
