Great White Sharks
by Erin Ryan The great white shark is one of the most recognizable sharks in the world. The only shark larger than a great white is the whale shark. 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. Like the Megalodon, great whites have huge triangle shaped teeth that are serrated, like knives.

It sweeps the tail side to side and can reach speeds of up to fifteen miles per hour (twenty-four kilometers per hour). and can have sudden
