American beaver
(Castor canadensis)
walrus
Description
This species is the largest rodent in North America. They are semi-aquatic and have many traits suited to this lifestyle. They have a large flat paddle-shaped tail and large, webbed hind feet reminiscent of a human diver's swimfins. Their un-webbed front paws are smaller, with claws. The eyes are covered by a nictitating membrane which allows the beaver to see underwater. The nostrils and ears are sealed while submerged. A thick layer of fat under their skins insulates the beaver from their cold water environment.
Dimensions
Adults usually weigh from 24 to 71 lb. Their head-and-body length is 29 to 35 inches, with the tail adding a further 7.9 to 14 inches.
Diet
They eat bark and cambium (the softer growing tissue under the bark of trees). Their favorites include willow, maple, poplar, beech, birch, alder, and aspen trees. They also eat water vegetation, as well as buds, and roots.
Habitat & Range
They inhabit lakes, ponds, rivers and streams, swamps, marshes and bogs. They are found throughout all of North America except for the northern regions of Canada and the deserts of the southern United States and Mexico.
Conservation status
