muskrat

n. large water rat (native to North America) that has a musky odor and whose light brown fur is harvested for commercial use in the fashion industry

The Muskrat or Musquash (Ondatra zibethicus), the only species in genus Ondatra, is a large aquatic rodent native to North America, and introduced in parts of Europe. It is nicknamed Swamp Bunny in the Mid-Atlantic States, especially in the marsh-lands and rivers surrounding the Chesapeake Bay. Adult body length is usually between 25-40 cm long, with a strong, laterally compressed tail 20-25 cm long. The body is covered in thick, brown waterproof fur; the underparts are paler. In brackish waters of Delaware, Maryland, New Jersey, and Virginia the black muskrat lives with brown muskrats. They have partially webbed hind feet and small able hand-like front feet. The weight is up to 1700 g (about 4 lb), about four times the weight of a Brown Rat.
