Crayfish clones create chaos

A mutant crayfish has learned to clone itself and is invading Europe and beyond.

An accident at a German aquarium has enabled an invasive species to reproduce itself and has reached as far as Africa, damaging ecosystems along the way. The marmokrebs, or marbled crayfish, appeared virtually overnight.

In 1995, a German pet store reportedly bought a few Texas crayfish and a single mutation from one of the fish created a whole new species that was able to clone itself. The mutation made the fish female, each one of them capable of reproducing exact copies of itself and creating an entire population, it was reported in the International Business Times.

 After escaping into the wild, the crayfish rapidly took over German waters, spread across Europe and has even reached the African continent over the last 20 years.
