Etymology: From Spanish nutria (“otter”), from Latin lutra.

1. The coypu, Myocastor coypus.

   “1986, Identifying and Managing Aquatic Rodents in Texas, Texas Agricultural Extension Service, page 13, Nutria are native to South America and were successfully established in North America in the early 1930s as a new furbearing species.”

   “Furthermore, nutria engage in the outright destruction of muskrat lodges to create nesting habitat for themselves.”
