Let’s try to discuss these points so the next time you see these creatures, you would be able to point which is dolphin and which is the porpoise.

Though both are toothed whales, they come from different family of mammals. Porpoise come from the Phocoenidae species while dolphins come from Delphinidae species. Given that they came from two dissimilar families, porpoise are quite smaller in size as compared to dolphins but are chubbier. Their dorsal fins also differ in such a way that porpoises have triangle fin that looks like the shark’s fin. The dolphin’s dorsal fin is shaped like a wave ‘“ it is taller but curved to the back.

Also, dolphin’s nose is a pointed beak while porpoise has a shorter but rounded nose. Their teeth are also different. The teeth of the dolphin are sharper cone-shaped while the teeth of the porpoise are flat and looked like a spatula. They also differ in their behaviors.
