They are the largest rodents in North America. Rodents are a family of mammals that gnaw (chew) with 2 pairs of sharp, front teeth (incisors). These incisors never stop growing so are always sharp. Beavers weigh from 40 - 100 pounds. They have a large, flat, scaly tail that they slap on the water when they are frightened. They have webbed back feet. They can close their throats while they carry sticks in the water so they won’t drown.
