White sharks are gray to brown above and fade to dirty white around their belly. A distinctive black spot can be found just behind the base of each of their two pectoral fins. White sharks are large, full bodied fish with conical snouts. Their lunate tail fin has caudal keels and lobes of equal length. The teeth of a white shark are large and triangular with serrated edges. These fish average about 15 feet in length and weigh approximately 1,500 pounds
