Beaver

Beavers live in riparian wetlands and are known for their ability to chew through small and medium-sized trees to create their dams. These dams serve as shelter from predators and nesting areas for beavers. Adult beavers can weigh up to 55lbs. The Capybara is the only rodent that grows larger than beavers.

One interesting feature of the beaver is its large, broad tail. When a beaver slaps its tail against the water, it is warning nearby beavers that there is danger. They also have webbed back feet, which helps them swim.
