|Muskrat range (native range in red, introduced range in green. Introduced range in South America not shown.)|
Muskrats are rodents that live in freshwater and saltwater marshes, lakes, ponds, and streams. Muskrats often build dome-shaped houses in marshes. These houses, made of plants, protect the muskrat from predators, since the only entrance is underwater. Some muskrats live in burrows on the water banks. Muskrats are excellent swimmers but are slow on land.
