A rare sighting of a black-and-white speckled dolphin stunned whale-watching spectators off the Southern California coast on Monday.
The bottlenose dolphin named "Patches" was spotted swimming southwest in a pod of 40 other dolphins about four miles off Dana Point, in Orange County, the OC Register reported.
Robin Lowe, a naturalist with the American Cetacean Society, was the first person to see the distinctive creature while aboard the Dana Wharf Whale Watching tour, according to the Register.
"Patches" was first seen in SoCal back in 2006, and since then, there have been infrequent sightings of the dolphin from Palos Verdes to San Diego. His unique coloration is a result of leucism, which is a condition in which a partial loss of pigmentation causes an animal to have white, pale or patchy discoloration of the skin, hair, feathers, scales or cuticles.
