Dolphin

A dolphin is a member of several groups of toothed cetaceans. The common name includes oceanic and river-associated forms. Sound production and sensing are important in many species, but the name does not imply identical sensory or social behavior throughout the grouping.

A bottlenose dolphin is a toothed cetacean of the genus Tursiops. These dolphins are studied for flexible foraging and social behavior as well as underwater acoustic sensing. Different populations can use different learned behaviors.
