American beavers are brown, semiaquatic rodents that can weigh up to 71 pounds and reach up to three feet in length, not including their tail. Beavers, as a whole, are one of the few animals that can actively change an ecosystem. Well-known for their ability to build dams, they block waterways with trees and mud, often creating new lakes, ponds, and floodplains. They also build homes, called lodges, out of branches and mud. These structures are often only accessible from underwater entrances.
Interesting Fact 1
The American beaver is the largest rodent in North America and the second-largest in the world, behind only the South American capybara.
Interesting Fact 2
They have a large, flat, paddle-shaped tail and large, webbed hind feet that help with swimming. Their unwebbed, highly dexterous front paws allow them to dig and manipulate plant materials, like sticks.
Interesting Fact 3
Their eyes are covered by a membrane that lets them see under water, and they can seal their nostrils and ears while submerged.
