Great white sharks have been found in each of the world's oceans. Even though they have been spotted in waters as shallow as three feet (one meter) deep, these sharks spend most of their time in deep coastal waters. The great white shark is related to the prehistoric Megalodon shark, which grew to over sixty-five feet (20 meters). The largest great white sharks found have been over twenty feet (six meters) long.
