The term 'DOLPHIN's Kin' refers to two species of aquatic mammals, the ORCA (also known as the Killer Whale) and the PORPOISE. The ORCA is a large, toothed whale that is found in all oceans and is the largest member of the DOLPHIN family. The PORPOISE is a smaller, toothed whale that is found in coastal waters around the world and is closely related to dolphins. Both species are highly intelligent and social animals that live in pods and communicate with each other using a variety of vocalizations.
