The Chinese White Dolphin (Indo-Pacific Humpback Dolphin, Sousa chinensis chinensis; traditional Chinese: 中華白海豚; pinyin: Zhōnghuá bái hǎitún ) is a Humpback dolphin species, one of eighty cetacean species. An adult is white or pink. Uniquely, the population along the Chinese coast has pink skin.[2] Pink skin is not pigment, but blood vessels for thermoregulation. The adult's body length is 200 - 350 centimetres and the infant's body about 1 metre. An adult weighs 150 to 230 kg. A Chinese White Dolphin lives 40 years, which can be determined by teeth.
The Indo-Pacific dolphins are in Southeast Asia, and they breed from South Africa to Australia. There are two subspecies, with Sumatra, one of the Indonesian islands, as the dividing line between the Chinese and the Western subspecies, Sousa chinensis plumbea. The two subspecies differ in color and dorsal fin size. The subspecies found in Southeast Asia has pinkish white skin and a larger dorsal fin but lacks the fatty hump of South African and Australian relations.
At birth, the dolphins are black. They change to grey, then pinkish with spots when young. Adults are white.
