What is the difference between porpoises and dolphins? |
Marine dolphins (family Delphinidae) and porpoises (family Phocoenidae) together comprise about 40 species. The chief differences between dolphins and porpoises occur in the snout and teeth. True dolphins have a beaklike snout and cone-shaped teeth. True porpoises have a rounded snout and flat or spade-shaped teeth.
