common porpoise

Did you know dolphins are actually toothed whales? 

All whales are generally divided into two groups, baleen whales and toothed whales, with the latter category including dolphins and porpoises. Common dolphins like this one can be spotted in several national marine sanctuaries, including Stellwagen Bank National Marine Sanctuary, where this one was photographed.
