The Nutria, or Coypu, is large, herbivorous, semi-aquatic rodent from South America that was introduced to North America and British Columbia in the 1930's for fur farming (1938 in BC). Superficially, the Nutria resembles the Beaver and the Muskrat. However, it is smaller than a beaver and lacks the large flat tail (the Nutria's tail is smaller and cylindrical) and is larger in size than a muskrat.
