The Indo-Pacific humpbacked dolphin (''Sousa chinensis'') is a species of humpback dolphin that is found in coastal waters ranging from southern Africa in the west to northern Australia and southeast Asia to the east.〔 The Indo-Pacific humpback dolphin is regarded as near threatened by the International Union for Conservation of Nature (IUCN).〔 ==Range and habitat== There are two varieties, regarded by some biologists as separate subspecies: *''Chinensis''-type (Chinese white dolphin) is the eastern variety, found in Southeast Asia and northern Australia *''Plumbea''-type is found in western variety, found along the eastern coast of Africa and the northern Indian Ocean along the southern coast of the Middle East through 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.〔 The Indo-Pacific humpbacked dolphin is a coastal species, generally staying within a few miles of the shore and preferring water less than deep.〔〔 Sometimes it enter rivers, but usually does not swim far upstream.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Indo-Pacific humpbacked dolphin」の詳細全文を読む スポンサード リンク
