Rare albino dolphin spotted off California coast

A 3-year-old albino dolphin was spotted swimming with its mom in California’s Monterey Bay last week, and the little one appears healthy, scientists say.

The crew of a Blue Ocean Whale Watch boat saw the albino Risso’s dolphin (Grampus griseus) swimming with its mom on June 7 about 3 miles (nearly 5 kilometers) offshore near Moss Landing. They identified it as the same animal that was last seen on Sept. 29, 2015, said Kate Cummings, a naturalist and co-owner of the whale-watching company. Before that, other tour operators had seen the albino animal in Monterey Bay in 2014, when it was a small calf, she said.

Albinism in the wild is incredibly rare, and I believe this is the only known albino Risso’s dolphin in the eastern Pacific,” Cummings told Live Science. [See Photos of the Rare Albino Risso’s Dolphin]

Albino animals like this one are white (or pink) because the cells that normally produce melanin the pigment that gives skin, hair and eyes their coloration are not doing their job (or not doing it well). Its pink eyes result from light reflecting off the red blood vessels in the dolphin’s retinas, the light-sensitive tissue at the back of the eye. Nonalbino animals have melanin in their pupils that absorbs incoming light, keeping it from reflecting off of the retina.
