Small, bluish-gray, and speckled, the marbled crayfish would be easy to overlook. Except for the fact it is likely to be coming to a pond or river near you soon—if it is not already there. The all-female freshwater crustacean has become a focus of fascination for scientists in recent years, due to its unique ability among decapods—the family that includes shrimps, crabs and lobsters—to clone itself and quickly adapt to new environments, as well as the fact that it has spread exponentially.
“All marbled crayfish share the same genome,” he says on a video call from his office in Heidelberg. “But they also adapt to various different environments, and do that in a hurry, which makes them scientifically remarkable and similar to a tumor, which also adapts to its environment.”that established the extraordinary fact that all marbled crayfish originate from a single foundational female. They reproduce without sex through parthenogenesis.
Hidde is earning less for the marbled crayfish because, he believes, officials are “wary of creating demand” for the cloned animals, which could promote their breeding and exacerbate the problem. “I may give up, unless they’re prepared to make it worth my while,” he says, admitting he had personally yet to develop a taste for the meat.
When Adriantsoa first went to work for the department of invasive species control at the University of Antananarivo in the Madagascan capital, the emphasis was on stopping the spread of the marbled crayfish, which are highly destructive, eating fish larvae; displacing native crayfish; and destroying the nation’s staple food crop, rice.
Hi, I am a structural engineer from Iran who have many ideas. I have summarized some of my ideas on my twitter(I suggest look at the idea of generating electricity by gravity). I want to work with companies and investors. Do you want to cooperate?
Easy problem, send em to me and I'll dispose of those no problem! Some potatoes, corn cobs, and sausage tossed in a good dry seasoning will solve any invasive species.
Wahu!!!
