The beaver is a large, semi-aquatic rodent known for its strong teeth and flat tail. They are primarily found in North America and Europe, living in rivers, streams, and ponds. Beavers are famous for building dams using branches, mud, and other materials, which create ponds that provide them with a safe habitat. Beavers are herbivores, mainly eating the bark, leaves, and twigs of trees and shrubs. They play a crucial role in their ecosystems by creating wetlands, which support diverse wildlife and help improve water quality. Their activities can also influence the surrounding landscape, promoting biodiversity.
