Coypu Myocastor coypus

Coypu
The Coypu, called Nutria in North America, is a cat-sized rodent. It is vegetarian and semi-acquatic like a cross between its water-loving larger relative the Capybara and a Water Vole. It nests in burrows by water. It is native to the southern half of South America but has feral populations (escapees from fur farms) in parts of North America, Europe, Africa and Asia (those in the UK were eradicated in the 1960s and again in the 1980s).
