white shark,

large, ferocious shark, Carcharodon carcharias. Also known as the great white shark and maneater, this shark can attack swimmers and boats without provocation, though it does not typically do so. Although not abundant anywhere, it is widely distributed in tropical and temperate oceans and is found in both inshore and deep waters; it is most common on the Atlantic coast of the United States. Like the other members of its family, the makomako
, heavy-bodied, fast-swimming shark, genus Isurus, highly prized as a game fish. Also known as the sharp-nosed mackerel shark, it is a member of the mackerel shark family, which also includes the white shark and the porbeagle.

 and the porbeagle, it is a fast swimmer, with large pectoral fins and a nearly symmetrical tail fin. Despite its name, the white shark is usually whitish only on the underside, the back being some shade of gray. It has dark-tipped fins and a conspicuous black spot behind the pectorals. It reaches a length of over 20 ft (6 m) and a weight of over 7,000 lb (3,180 kg); one study has suggested that some individuals may live for 70 years or longer. The white shark feeds on large fish and other animals; a 100-lb (45-kg) sea lion was recovered from the stomach of one specimen. The shark's serrated, triangular teeth were used as arrowheads by Native Americans of the Florida coast. The white shark is 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.
