Beavers are a small, brown animal related to the squirrel. They are found in America and Europe. They spend their time in and around water, and are excellent swimmers. Beavers are best known for their ability to build dams. They cut down trees with their sharp teeth and drag the logs to where they need them, and stack them up to make a dam. They end up with their own ponds that they tend to, which protects their den. Beavers eat waterlilys.
