Illustration of Nutria (Myocastor coypus)

The Nutria is a large, South American semi-aquatic rodent introduced to North America for the fur trade that has become highly invasive in Gulf Coast marshes and Mid-Atlantic wetlands. Its voracious feeding habits devastate native marsh vegetation, converting productive wetlands to open water in a process called 'eat-outs.' Orange-stained front teeth are a distinctive and unusual feature of this species.
