Chinese white dolphin The Chinese white dolphin is a variety of Indo-Pacific humpbacked dolphin ("Sousa chinensis"; ). This variety inhabits the eastern portion of the species range, in Southeast Asia and Australia. Some biologists regard the Chinese white dolphin as a separate subspecies, "Sousa chinensis chinensis", from the "Plumbea"-type Indo-Pacific humbacked dolphin, which lives in the western part of the species range, from east Africa to India. However, DNA testing has indicated that the "Chinensis"-type dolphins from Southeast Asia are more closely related to the "Plumbea"-type dolphins than they are to the "Chinensis"-type dolphins from Australia.
