Chinese White Dolphin

The Chinese white dolphin (Sousa chinensis) inhabits the waters of Southeast Asia and is a humpback dolphin species. Its body length is 2 - 3.5m (6ft 7in - 11ft 6in) for adults and 1m (3ft 3in) for infants. At birth, the dolphins are black but they change to grey, then pinkish with spots when young. By the time they reach adulthood they are white. According to the World Wide Fund for Nature, the Chinese white dolphin was first recorded in Hong Kong waters as early as the 1600s and its habitat spans the Pearl River Estuary.

Pink dolphins in the Pearl River estuary face a far greater extinction threat than previously thought, with crucial habitats in the area disappearing and the species population declining at an annual rate of 2.5 per cent, a study has found.
