These Risso Dolphins were in St Mary's Roads yesterday afternoon
Risso's dolphin has a relatively large body and dorsal fin and a bulbous head
Infants are dorsally grey to brown and ventrally cream-colored, with a white anchor-shaped area between the pectorals and around the mouth. In older calves, the nonwhite areas darken to nearly black, and then lighten (except for the always dark dorsal fin). Linear scars mostly from social interaction eventually cover the bulk of the body. Older individuals appear mostly white.
