Castor canadensis

It's true!

• The American beaver is North America’s largest rodent and is ideally suited for its aquatic lifestyle. 
• As a rodent (Latin for “to gnaw”), a beaver must gnaw to wear down its front teeth, which never stop growing. 
• Beavers do not eat fish or other aquatic animals, but love willow and aspen bark as well as the roots of pond lilies. 
• Beaver dams are made of tree trunks, branches, sticks, and mud, reaching 6 - 8 feet tall and 1/4 mile long.
