Rare Pink Bottlenose Dolphin

A rare pink Bottlenose dolphin, Tursiops truncatus, has resurfaced two years after it had first been seen in Lake Calcasieu, an inland saltwater estuary, north of the Gulf of Mexico in southwestern Louisiana.

The young dolphin, which was first sighted as a calf in June 2007 and photographed a few weeks later, gets its brilliant pink color and bright red eyes from blood vessels that lie just below its layer of blubber. This pink color is masked by pigments in the skin of normally-colored gray animals.
