Muskrats are stocky, broad rodents that make burrows in the banks of waterways. Special adaptations allow them to live a semi-aquatic lifestyle. They have insulating and buoyant brown fur, partially webbed hind feet and a scaly tail. Their teeth protrude in front of its lips to keep water out while they gnaw on plants. Muskrats are known for the musky-like odor that gave the animal its name.
