"When the Louisiana crawfish is present in the amphibian laying site pool, pond or marsh we have observed different mutilations of amphibians: cut skin, leg amputations," [Jean-Marc Thirion] said. "When the Louisiana crawfish population is established after a few years in the same site, we note the extinction of amphibian species."
No, we can't have frogs exterminated in France. It's too symbolic.
Well, then the Germans could have it without having to have a WW over it again...
