The beaver is a large, semi-aquatic animal. Beavers usually live in forests in North America. They are also found in parts of Europe and Asia. They are good swimmers and can swim up to 8 kilometers per hour. And they can swim underwater for up to 15 minutes. Their ears and nostrils can close while they are underwater. Their eyelids protect their eyes while swimming.
The beaver is the largest rodent in North America. Adult beavers weigh about 20 kilograms. But they can be as large as 35 kilograms. They are about 30 centimeters tall and about 90 centimeters long. Their flat, thick tail is about 30 centimeters long. The wide tail acts as a flapper while swimming. Their fingers have long claws, and the legs have webbed feet and claws. Beavers are plant eaters. They eat tree bark, leaves, roots, and water plants.

Beavers build dams in a stream or river to create homes. They build dams using sticks, bark, mud, and logs. Beavers cut down trees for the dams, using their strong teeth. Beavers build dams that change the course of streams and create ponds. Each beaver pond is inhabited by one beaver family - two adults and usually 2-4 young beavers. When the food supply around the beaver¡¯s home is dried up, they move to another place and start building a new dam.

Beavers mate in January or February. The babies are born in early spring. When the young beavers become 2 years old, they start building and maintaining dams with adults. They reach adulthood during their second winter. Then, they move away to find a mate and build their own dams. In the wild, their life span is about 20 years.
