They also dont leave behind any seeds so that the plant can regrow, thus devastating certain areas or habitats. [15] According to the Louisiana Department of Wildlife and Fisheries, nutria were also transplanted from Port Arthur, Texas, to the Mississippi River in 1941 and then spread due to a hurricane later that year.

The main physical difference between these two is that nutrias have extremely long and rat-like tails, while capybaras do not have a tail at all. On nearby Tristan da Cunha, black rats have already devoured a separate petrel population. Nutria meat is leaner with a lower fat content and lower in cholesterol compared to ground beef.
