Beavers are industrious mammals known for their impressive ability to construct dams and lodges using wood. They have a flat, paddle-like tail and sharp incisor teeth that enable them to fell trees and shape their environment. These semi-aquatic creatures are often found near bodies of water, such as rivers and ponds, where they create intricate systems of canals and ponds by manipulating the flow of water. Their diligent work has a significant impact on ecosystems, providing habitats for various plants and animals.
