Muskrat

This medium-sized mammal has short front legs with small feet, stronger hind legs with large feet, and a vertically flattened, scaly tail that is slightly shorter than the combined length of head and body. The hind feet are partially webbed. The back is blackish brown and the sides are lighter brown with a reddish tinge; the underparts are still lighter, shading to white on the throat. Their musk glands produce a mild and inoffensive odor.
