The American beaver (Castor canadensis) is among the largest rodents and occurs in and around lakes, ponds, and streams throughout North America, from coast to coast, except in the Arctic tundra and southern deserts.They are important landscape engineers, cutting down trees of all species to build elaborated dam systems, up to 3 m high and containing water over impressive flooded areas. They are aquatic rodents and have a number of adaptations that make them adept swimmers including webbed feet and a broad, flat tail that is covered with scales. It will also slap its tail against the water to signal danger or to warn away predators. Adaptations - Dams and Lodges.
