The Beaver is an aquatic species of rodent that is easily recognized by its large size, small ears and eyes, brown coloration, and large flat, broad, scaly tail. The tail is slapped on the water to create an alarm sound when threatened. Adults weigh from 16 to 32 kg and, including the tail, may be up to 1.3 m long (Hinterland Who's Who 2011). It has strong teeth, including large, orange incisors. The front feet are clawed and the hind feet are webbed (Nagorsen 2005).
