This species can be identified by its large dorsal fin, almost-square head, and often through extensive scarring on the body, especially on older adults. Color can range from dark gray to almost white.

A Risso's Dolphin loafing off the Channel Islands NP, California (9/3/2013). The marks on the back are from other Risso's tooth-marking and from the squid on which they prey. These markings are used by researchers to track individuals and groups. Photo by Nancy Magnusson. (MBP list)
