Beavers: Gnawers of the Northern Woods
How would you like to eat part of your house for food during the winter? Well that's just what beavers do. Beavers are animals that live in the water. They spend most of their time there, even though they are mammals. That means they breathe air, so part of the time they are also on land.
Beavers live in the water because it is safer for them. They can't run very fast, but they swim great.
