The mutant crayfish that ate Europe

[DavidBrown]

A crayfish species has evolved in a (possibly, no one is really sure) German aquarium via a mutation in its sex cells. The marbled crayfish is a female clone species.

The invasive species is moving throughout Germany and somehow also in Madagascar.

Do any aquariums or zoos hold this species?

I've seen and photographed it at Wüppertal zoo.

The story reminds me the seaweed Caulerpa taxifolia. One of the worst invasive species of the world, also because of a mutation suffered in European aquariums due to chemicals used in aquarium keeping, while in it's natural habitat the original plant is much more tender, smaller and not invasive.
