Myocastor coypus


It somewhat resembles a very large rat, or a beaver with a small tail. Adults are typically 4–9 kg (8.8–19.8 lb) in weight, and 40–60 cm (16–24 in) in body length, with a 30- to 45-cm (12- to 18-in) tail. It is possible for nutria to weigh up to 16 to 17 kg (35 to 37 lb), although adults usually average 4.5 to 7 kg (9.9 to 15.4 lb). They have coarse, darkish brown outer fur with soft dense grey under fur, also called the coypu, nutria. Three distinguishing features are a white patch on the muzzle, webbed hind feet, and large, bright orange-yellow incisors. The nipples of female coypu are high on her flanks, to allow their young to feed while the female is in the water.


Originally native to subtropical and temperate South America, it has since been introduced to North America, Europe, Asia, and Africa, primarily by fur ranchers.
