What are the differences between dolphins and porpoises?
There are several major differences between dolphins and porpoises: 1) Dolphins have a longer and more pronounced beak (or rostrum) than a porpoise. 2) Most of the vertebrae in a dolphin’s neck are separate units, which gives them the ability to turn their head. All vertebrae in a porpoise’s neck are fused, which means they cannot turn their head to look left and right. In order to do so, they must turn their entire body. 3) Porpoises are generally smaller than dolphins. 4) Dolphins have cone shaped teeth. Porpoises have spade shaped teeth.
