The North American Beaver (Castor canadensis) lives in Canada, most of the United states and Northern Mexico. It is the second largest rodent in the world, the largest rodent in the world is the capybara. The North American Beaver has webbed hind feet for swimming and unwebbed front paws (clawed, used for digging and carrying material for dams for example). In some areas they are viewed as pests, because they flood rivers with their dams and are very persistent to repair any damage to the dam. Most of the time, the only way to stop them is to move them to another location. Predators of the North American Beaver are the Red Fox, Gray Wolf, Bobcat and the Coyote.
