Myocastor coypus (nutria)

Language: French

Wikipedia Abstract

Nutria redirects here.The coypu (from Spanish coipú, from Mapudungun kóypu) (Myocastor coypus), also known as the river rat or nutria, is a large, herbivorous, semiaquatic rodent and the only member of the family Myocastoridae. Originally native to subtropical and temperate South America, it has since been introduced to North America, Europe, Asia, and Africa, primarily by fur ranchers.

Infraspecies

Invasive Species

Myocastor coypus (coypu) is a large semi-aquatic rodent which originated from South America. However, due to escapes and releases from fur farms there are now large feral populations in North America, Europe and Asia. Their burrows penetrate and damage river banks, dykes and irrigation facilities. Myocastor coypus' feeding methods lead to the destruction of large areas of reed swamp. Habitat loss caused by coypus impacts plant, insect, bird and fish species.
