Long-Beaked Common Dolphin

Long-beaked common dolphin, Delphinus capensis, pacing the boats in San Diego Bay. It's tough to tell the difference between these and their cousins, the short-beaked common dolphin, Delphinus delphis. However, the long-beaked common dolphin is more frequently found in shallow coastal waters while the short beaked dolphin is found in deeper water along the edge of the continental shelf and along sea mounts.
