Black has up-loaded some pictures of coypus:
... from Argentina.... which surprised me because I'd always taken them to be Eurasian. But no, apparently exported from South America to most of the world:

I've seen them in southern France and elsewhere where they don't seem to be a difficulty but when they established on the Norfolk Broads in UK they were definitely a problem and had to be eliminated.
Just wondered if anyone else has difficulties with them?
