The most obvious visible difference between the two groups is that porpoises have spatulate (flattened) teeth distinct from the conical teeth of dolphins. Compared with dolphins they rear more young more quickly than dolphins. Porpoises tend to be smaller but stouter than dolphins. They have small, rounded heads and blunt jaws instead of beaks. Their teeth are spade-shaped, whereas dolphins have conical teeth. In addition, a porpoise’s dorsal fin is generally triangular, rather than falcate (curved) like that of many dolphins and large whales.
