Rissos dolphins surfacing, one spouting/blowing while others show dorsal fins. Note distinguishing and highly variable skin and dorsal fin patterns, characteristic of this species. White scarring, likely caused by other Risso dolphins teeth, accumulates during the dolphins life so that adult Rissos dolphins are almost entirely white. San Diego.
