The American beaver is the largest rodent in the United States, growing from two to three feet (0.6 to 0.9 meters) long, not including the tail. They have dark-brown waterproof fur and webbed feet. Beaver teeth grow continuously throughout their lives, and beavers must gnaw on trees to keep their teeth from getting too long.
