In 2003, Gerhard reported the first parthenogenetic decapod, a cambarid crayfish (Marmorkrebs) found in the aquarium trade. It was subsequently shown that these animals originated in Florida, and molecular evidence revealed that they were in fact a form of Procambarus fallax that has established itself in several European countries as well as Madagascar, thus uncovering a harmless pet primed to become a devastating invasive species.
In his comments, Dr. Scholz offers this bon mot:
Life without crustaceans is possible, yet pointless!
