The bottlenose dolphin grows to 6-13 feet and weighs between 350-450 pounds on average. It has medium gray colorings on its back, and lighter gray to a white or pale pink on its underside. It has a well defined snout, or "beak". The bottlenose dolphin's brain is larger than that of a human's, and the species exhibits a wide range of vocalizations for communication. It is a very social species, and can typically be seen jumping and leaping during play or mating.
