Beaver

(Castor fiber) The beaver is known as a lumberjack and a master at building dams. It is the biggest rodent in the northern hemisphere. After having been endangered in many countries, it has recovered today thanks to extensive protection measures and reintroduction into their natural habitats. The beaver is a primarily nocturnal, large, semiaquatic rodent that lives in lifelong partner relationships. It is an excellent swimmer, good at diving and it can stay under water for up to 15 minutes. The beaver digs in the embankment and uses branches and mud to build a hut with an underwater entrance. It can cut down trees with a diameter of up to 50 cm.  The beaver eats a vegetable diet, beach vegetation, leaves, bark and soft tree parts.

The beaver's fur is brown and very dense. The coat protects the animal against supercooling. The beaver continously cleans its fur and rubs it with a greasy substance, castoreum. The beaver has webbed hind feet and a broad, scaly tail.
