Procambarus fallax
Slough Crayfish, Deceitful Crayfish
Procambarus fallax is a freshwater crayfish native to peninsular Florida and southern Georgia, USA, where it inhabits tributaries of the Satilla River. The species is notable as the sexual parental species of the parthenogenetic Marmorkrebs (marbled crayfish), which originated as a single lineage from P. fallax through apomictic parthenogenesis. While P. fallax reproduces sexually with separate males and females, its parthenogenetic derivative has achieved global distribution through the aquarium trade and exhibits high invasive potential due to single-female founding capability.
