Lakeshark
A lakeshark is quite simply, a variety of shark that lives in freshwater lakes. They eat canoes, left shoes and the occaisonal child. For a real treat, they will enjoy a history teacher. They range in size from a metre to 4 meters long. Swimmers and boaters alike are told to watchout, as they can attack at any time.
Dang lakesharks! We would have won that race if they hand't gotten to our canoe.
