How do you tell a dolphin from a porpoise? These two mammals are easy to confuse. Then how do you know? One way to tell them apart is to look at their beaks. Dolphins usually have beaks, porpoises do not. What's a beak? A beak is like a snout, only longer. Dolphins also have more noticeable dorsal fins. Another way to find out can only be used if you get close enough to the dolphin or porpoise. Check their teeth! A porpoise's tooth is in the shape of a spade, while a dolphin's tooth is more in the shape of a spike. One of the dolphins that is easily confused as a porpoise is the Irrawaddy Dolphin. This is due to the fact that it has barely any beak. Other dolphins to watch out for is the Hourglass Dolphin, the Dusky Dolphin, the Peale's Dolphin, the Pacific White-sided Dolphin, Atlantic White-sided Dolphin, Fraser's Dolphin, Southern White Whale Dolphin ( no beak or dorsal fin ) Northern Right Wale Dolphin ( also no beak nor dorsal fin) Hector's Dolphin, Heavisides Dolphin, Chilean Dolphin, and the Comersons Dolphin.
