1. Beavers can cut down hundreds of trees every year! Using their strong orange teeth like little chainsaws, a single beaver can chew down up to 200 trees a year to use for building dams and houses.

2. Their lips close behind their teeth. Beavers have a special feature: their lips can seal shut behind their front teeth. This lets them chew on wet wood underwater without getting a mouth full of lake water and mud!

3. Beaver ponds help other animals survive. By building dams, beavers create wetlands that give homes, water, and safe breeding grounds to hundreds of other animals, like frogs, ducks, fish, and moose.

4. They don't hibernate in the winter. When it gets freezing cold, beavers stay awake! Before winter arrives, they pile up extra branches and yummy food stems on the muddy bottom of their pond near their lodge so they can snack all winter long.

5. Baby beavers are called kits. Baby beavers are born inside the cozy lodge in the spring. They are furry, have their eyes wide open, and can even swim just a few hours after being born!

6. They have double layers of fur. To stay warm in icy water, beavers have two layers of fur: a short, fluffy layer that traps warm air next to their skin, and a longer waterproof coat on top.

7. They can chop down trees while swimming. Because their lips close behind their teeth, beavers can actually gnaw through tree roots or branches that are partially submerged in water without drowning or choking.
