The Nutria or the Myocastor coypus is a big semi-aquatic rodent. This generic name is descended from two Greek words “mys” for mous ad “kastor” for beaver, which translates to as a mouse beaver.
Nutria is much smaller than a beaver; however, a bit bigger than a muskrat. Compare to beavers, it has a slightly and round haired tail.
Its forelegs are quite small compared with the size of its body. Male are slightly bigger than females. They weight an average of 5.4 kg.
