The beaver is a large, semi-aquatic rodent known for its distinctive flat tail and webbed feet. They are primarily found in North America and Europe, living in freshwater habitats like rivers, lakes, and ponds. Beavers are known for their impressive building skills, creating dams from branches, mud, and stones to create ponds that provide safety from predators. Beavers are herbivores, primarily feeding on the bark, leaves, and twigs of trees and shrubs. Their activities play a crucial role in the ecosystem by creating wetlands, which support diverse wildlife and improve water quality. The beaver's scientific name is Castor, and they are recognized for their strong teeth, which continuously grow to help them gnaw through wood.
