Nutria also known as coypu and river rat

Once when I was walking in city park I meet this friend. It is known as Nutria or Coypu.

The coypu (from Spanish coipú, from Mapudungun koypu;] Myocastor coypus), also known as the nutria, is a large, herbivorous, semiaquatic rodent. It has been classified for a long time as the only member of the family Myocastoridae. However, studies based on the comparison of DNA and protein sequences showed that Myocastor is nested within Echimyidae, the family of the spiny rats. Originally native to subtropical and temperate South America, it has since been introduced to North America, Europe, Asia, and Africa, primarily by fur ranchers. Although it is still valued for its fur in some regions, its destructive feeding and burrowing behaviours make this invasive species's endurance controversial to human occupants throughout most of its range.

Coypus live in burrows alongside stretches of water. They feed on river plant stems.
