Indo-Pacific Humpback Dolphin

The Indo-Pacific humpback dolphin has a long beak and a dorsal fin set on a raised base or hump. Colour varies geographically and with age; dolphins around southern China often become pale grey or pinkish as adults, with visible blood vessels contributing to the pink appearance. The species occupies shallow coastal waters of the eastern Indian and western Pacific oceans. (Wikipedia, general species account)

It feeds on coastal fish, cephalopods and crustaceans in estuaries, river mouths, bays and reef systems. Groups are usually small, although animals gather where prey is concentrated. Its repeated use of nearshore habitat makes it one of the more readily observed cetaceans along suitable southern Chinese coasts. (Wikipedia, general species account)
