Similar in appearance:
* Muskrat: While smaller, muskrats share the same stocky build and rounded ears as beavers. They also have a similar reddish-brown fur. However, muskrats have a much longer tail, which is cylindrical and covered in scales, unlike the flat, paddle-shaped tail of a beaver.
* Nutria: These semi-aquatic rodents are larger than muskrats and have a similar build to beavers. They have a distinctive orange-brown fur and a thick, scaly tail that is slightly flattened.
* Capybara: The world's largest rodent, capybaras, share a similar body shape and build to beavers. They have a shorter tail, reddish-brown fur, and webbed feet.
Similar in behavior:
* Coypu: This large, semi-aquatic rodent is often confused with beavers due to its similar habits and appearance. It has a similar body shape and a long, scaly tail but lacks the beaver's distinctive paddle-shaped tail.
Remember:
* While these animals share some characteristics with beavers, they are distinct species with their own unique features and behaviors.
* To correctly identify a beaver, focus on its large, flat, paddle-shaped tail, its rounded ears, and its distinctive orange-brown fur.
