Marbled crayfish

Marmorkrebs, or marbled crayfish, are parthenogenetic crayfish that were discovered in the pet trade in Germany in the 1990s.[2] Marmorkrebs are closely related to the "slough crayfish", Procambarus fallax.[3] P. fallax is widely distributed across Florida,[4] but no natural populations of marmorkrebs are known. Information provided by one of the original pet traders as to where the marmorkrebs originated was deemed "totally confusing and unreliable".[5] Marmorkrebs is German for "marbled crayfish". -Wikipedia
