Procambarus acutus
White River Crayfish
Procambarus acutus, commonly known as the white river crayfish, is a freshwater crayfish species in the family Cambaridae native to eastern North America. The species exhibits a disjunct native distribution spanning from the Atlantic Slope to the Gulf of Mexico drainages. It has been introduced to multiple regions outside its native range, including parts of Europe and Africa, where it poses potential ecological and economic risks. Two subspecies are recognized: P. a. acutus and P. a. cuevachicae.
