Dorsal matchIn September 2015 Blue Ocean Whale Watch spotted an albino Risso's dolphin in Monterey Bay and got pictures of it with its mother. Then, on June 7, 2017, they spotted an albino Risso's dolphin with its mother in Monterey Bay and compared the dorsal fin IDs of the mother from each sighting to confirm they were a match. "We did this to make sure it was the same albino Risso's dolphin we had spotted two years ago. Besides being all white, [an] albino dolphin has no identifying marks, whereas the mother has unique pigment and scars to help identify her."

Searching for squidThe albino dolphin is likely about 3 years old, according to Kate Cummings, co-owner of Blue Ocean Whale Watch. The group was likely a nursery pod of dolphins searching for squid, their favorite food, Cummings said.

Peculiar scarsThe bodies of Risso's dolphins are typically heavily scarred. Squid and other prey leave circular markings on the dolphins. In addition, the dolphins' teeth raking up against one another also leave scars, according to the National Oceanic and Atmospheric Administration (NOAA).

Blunt foreheadRisso's dolphins are the only cetaceans with a vertical crease on the forehead. In addition, they have indistinguishable beaks, giving their face a blunt shape.
