All-female crayfish species causing trouble

A mutant species of all-female crayfish taking over the world is not the latest science fiction film but a real-life environmental thriller.

A new study has found that marbled crayfish are multiplying rapidly and invading ecosystems across the world.

The ten-legged pests are descended from one single female with a mutation allowing it to reproduce without males.

These self-cloning ladies are found for sale in North America, despite a warning against keeping them as pets.

Sales of the six-inch creature are already banned by the European Union.

Procambarus virginalis did not exist three decades ago.



Wow, I had no idea that such a species existed :O .

I can certainly see why reproducing so quickly would make them such a nuisance - but, I'm guessing their asexual reproduction would also leave them vulnerable to getting wiped out very quickly?

Wow. Real life Gerudos. (A cookie if you get the reference :P )

Between this and the feminisation of sea turtles due to temperature changes, I don't even know what to think anymore! :lol:
