The beaver makes its home in rivers, streams and ponds in North America and Europe. This mammal is about 1 meter long, including its tail. Living there is not easy, but the beaver's body and habits are a good match for it.
One reason the beaver survives is large orange front teeth that never stop growing, which let it chew through tree trunks. It also has a flat, paddle-shaped tail, which helps it steer in the water and slap a warning when danger is near.
The beaver is a herbivore, which means it is an animal that eats only plants. Its food includes tree bark, twigs and water plants. To find food, it builds dams of sticks and mud that turn streams into ponds.
Young beavers are called kits. Kits can swim within a day of being born but stay with their family for about two years. The ponds beavers create become homes for fish, frogs, ducks and many other animals.
