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

A new study has found that marbled crayfish are multiplying rapidly and invading ecosystems across the world.<\/p>\n

The ten-legged pests are descended from one single female with a mutation allowing it to reproduce without males.<\/p>\n

These self-cloning ladies are found for sale in North America, despite a warning against keeping them as pets.<\/p>\n

Sales of the six-inch creature are already banned by the European Union.<\/p>\n

Procambarus virginalis did not exist three decades ago.<\/p>\n

Born to a male and female slough crayfish, a species originally from Florida, the original marbled crayfish had an additional set of chromosomes – a mutation that made her distinct from her parents and allowed her to reproduce without having to mate.<\/p>\n

Now officially a separate species, the marbled crayfish can be found in the wild in Japan, Madagascar, multiple European countries and the US.<\/p>\n

The new study published in Nature, Ecology and Evolution describes the invasive species as a threat to wild ones, particularly seven native species in Madagascar.<\/p>\n

“If you have one animal, essentially, three months later, you will have 200 or 300,” Dr Wolfgang Stein, one of the researchers, told Canadian public broadcaster CBC.<\/p>\n

Dr Stein, who is a neurophysiologist at Illinois State University, told the BBC that they compared 11 marbled crayfish, spread through the pet trade to four locations on three continents.<\/p>\n
