Porpoises are small cetaceans that have a short, beaklike snout or no snout, a triangular dorsal fin, and spade-like teeth. They are Odontoceti (toothed whales).
The porpoises are small cetaceans of the family Phocoenidae; they are related to whales and dolphins. They are distinct from dolphins, although the word "porpoise" has been used to refer to any small dolphin, especially by sailors and fishermen. The most obvious visible difference between the two groups is that porpoises have spatulate (flattened) teeth distinct from the conical teeth of dolphins.
