Common Dolphin

Common Dolphin is the most abundant cetacean in the world, with an estimated global population of about six million. It is currently the only member of the genus Delphinus, the type genus of the subfamily Delphininae. This places it as a close relative of the bottlenose dolphin, humpback dolphin, striped dolphin, spinner dolphin, Clymene dolphin, spotted dolphin, Fraser's dolphin, the tucuxi, and the Guiana dolphin.

Common dolphin are medium-sized dolphins; adults range between 1.9 and 2.5 m (6.2 and 8.2 ft) long, and can weigh between 80–235 kg (176–518 lb), although the range between 80–150 kg (180–330 lb) is more common. The long-beaked common dolphin was thought to have a disjointed range in coastal areas in tropical and warmer temperate oceans; this range included parts of western and southern Africa, much of western South America, central California to central Mexico, coastal Peru, the seas around Japan, Korea and Taiwan, and possibly near Oman.
