Megalodon is a species of giant, prehistoric shark (though these statistics could also be used for any kind of giant shark). They generally range from 25 to 55 feet in length, and are apex predators, preying even upon whales and sea monsters. Like other sharks, they can smell blood in the water miles away, and they may have the same ability to detect the electromagnetic fields of living creatures as do great white sharks. They are otherwise much like any other shark, being swift and ravenous hunters.
