The beaver is a large, semi-aquatic rodent with a large, flattened tail. It is a strong swimmer and can swim up to 5 miles per hour (8 kph). The beaver can swim underwater for up to 15 minutes. Young beavers are called kits. Beavers live in forests in North America and in parts of Europe and Asia. Beavers do not hibernate over winter, but they will stay in their lodge, where they have stored enough food to last until spring.
