The Lamnidae are the family of mackerel or white sharks. They are large, fast-swimming sharks, found in oceans worldwide. The name of the family is formed from the Greek word, lamna, which means fish of prey, and was derived from the Greek legendary creature, the Lamia.[2]
These sharks have pointed snouts, spindle-shaped bodies, and large gill openings. The first dorsal fin is large, high, stiff, and angular or somewhat rounded. The second dorsal and anal fins are minute. The caudal peduncle has a couple of less distinct keels. The teeth are gigantic. The fifth gill opening is in front of the pectoral fin and spiracles are sometimes absent. They are heavily built sharks, sometimes weighing nearly twice as much as sharks of comparable length from other families. Many sharks in the family are among the fastest-swimming fish, although the massive great white shark is slower due to its great size.
