The North American beaver or Castor canadensis is one of two extant beaver species. It is native to North America and introduced to Patagonia in South America and some European countries (e.g. Norway). In the United States and Canada, the species is often referred to simply as a beaver, though this causes some confusion because another distantly related rodent, Aplodontia rufa, is often called the mountain beaver. Other vernacular names, including American beaver and Canadian beaver, distinguish this species from the other extant beaver species.

This beaver is the largest rodent in North America. Adults usually weigh from 24 to 71 lbs., with 44 lbs. being typical. In the Northwest Territory, adults weighed a median of 45 lbs. The head-and-body length of adult North American beavers is 29–35 in. with the tail adding a further 7.9–13.8 in.

Beavers are semiaquatic. The beaver has many traits suited to this lifestyle. It has a large, flat, paddle-shaped tail and large, webbed hind feet. The front paws are smaller, with claws. The forepaws are highly dextrous, and are used both for digging, and to fold individual leaves into their mouth and to rotate small, pencil-sized stems as they gnaw off bark. The eyes are covered by a nictitating membrane which allows the beaver to see under water. The nostrils and ears are sealed while submerged. A thick layer of fat under its skin insulates the beaver from its cold water environment.

The beaver’s fur consists of long, coarse outer hairs and short, fine inner hairs. The fur has a range of colors, but usually is dark brown. Scent glands near the genitals secrete an oily substance known as castoreum, which the beaver uses to waterproof its fur.
