The beaver is the largest rodent in North America. It is native to Canada, United States, and parts of northern Mexico. Most beaver are hunted for fur. They are dark brown with a thick layer of fat under the skin to insulate them from a cold water environment. A beaver’s diet consists of bark, twigs, and roots. It’s incisor teeth are large and bright orange, and used for gnawing. They are well known for building dams in rivers and streams. The dams they build can be disruptive by causing flooding, yet beneficial to restoring wetlands. Beavers build lodges to live in and the entrance is always underwater.
