Risso’s dolphins (Grampus griseus) are large light grey dolphins that can reach over 13 feet in length, and have a relatively tall, dark dorsal fin. Adults are typically covered with overlapping white scars caused by the teeth of their con-specifics making them look quite battered. They have a rounded head, lacking a beak, but have a deep vertical crease down the center of the forehead. As they mature, their forehead becomes prominently white, making them one of the easiest species to recognize at sea. Risso’s dolphins are commonly seen in the Abacos each winter and spring, primarily on the Atlantic side of the islands. It is unknown where these groups range the rest of the year, but some individuals have been seen off Abaco repeatedly over the years.
