Maybe, but they do get to 12'.
The porbeagle (Lamna nasus) is a common, fast-swimming, potentially dangerous shark. This mackerel shark can grow to be up to 12 feet (3.7 m), weighing about 350-550 pounds (155-225 kg). They are dark gray on top and white underneath; there is also a small patch of white on the rear edge of the dorsal fin. Porbeagles have a torpedo-shaped body and two keels on the wide tail (the second keel is a short ridge running along the upper part of the lower lobe of the tail), making it an efficient swimmer. The porbeagle feed on fish (mostly mackerel, squid, cod, hake, flounder and other bottom-dwelling fish) with its long, sharp teeth. It lives in cold waters down to about 1,200 feet (370 m). It must swim continuously to get oxygen. Porbeagles are functionally warm-blooded; they retain the heat generated by their muscles and recycle it to heat their body, keeping their body temperature up to 20°F (11°C) warmer than the cold waters they live in. Porbeagles are viviparous, with cannibalistic embryos in the womb; only 2-4 pups survive pregnancy. They live in the North and South Atlantic and the South Pacific Oceans. Order Lamniformes.
