They are distinguished from dolphins by their smaller size and their rounded, beakless heads. Porpoises are 4 to 6 ft (120–180 cm) long and are black above and white below. Traveling in schools, porpoises prey on fish, often pursuing them long distances up rivers. The finned porpoises, species of the genus Phocoena, have a dorsal fin. They are distributed throughout the world and include the harbour, or common, porpoise, P. phocoena, found throughout the Northern Hemisphere. The vaquita, P. sinus, found only in the N Gulf of California, Mexico, is the smallest and most endangered species. The finless porpoises, genus Neophocaena, are found in the Indian and W Pacific oceans and in the Chang (Yangtze) River. The fat of the porpoise yields a lubricating oil, and the flesh is sometimes eaten. In North America the dolphins (family Delphinidae) are sometimes called porpoises and the bottle-nosed dolphin is sometimes called the common porpoise. True porpoises are classified in the phylum ChordataChordata
, phylum of animals having a notochord, or dorsal stiffening rod, as the chief internal skeletal support at some stage of their development. Most chordates are vertebrates (animals with backbones), but the phylum also includes some small marine invertebrate animals.
