The Chinese White Dolphin (Sousa chinensis chinensis; Traditional Chinese: 中華白海豚; pinyin: Zhōnghuá bái hǎitún), also called Indo-Pacific Humpback Dolphin, is a subspecies of the Humpback dolphin and is one of eighty cetacean species. The adult dolphin is usually white or grey in colour. The population along the Chinese coast is unique in that they exhibit a pink-coloured skin.[1] This colour of the skin is not a result of colour pigmentation, but is actually from blood vessels used for thermoregulation to prevent overheating during exertion. The adult's body length is about 220 - 250 centimetres and the infant's body length is about 1 metre. The average weight of an adult is around 150 to 230 kilograms.
The Indo-Pacific dolphins can be found throughout 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 size of their dorsal fin.
The subspecies found in Southeast Asia has pinkish white skin and a larger dorsal fin but lacks the fatty hump of its South African and Australian counterparts.
[edit] Color changes in growth period
