Procambarus fallax (also known as deceitful crayfish [1] or slough crayfish [2] [4]) is a species of crayfish in the genus Procambarus. It lives in tributaries of the Satilla River in Georgia and Florida. [1] [2] It is the closest relative to the parthenogenetic marbled crayfish, Procambarus virginalis. [5] [6]
Procambarus is a genus of crayfish in the family Cambaridae, all native to North and Central America. It includes a number of troglobitic species, and the marbled crayfish (marmorkrebs), which is parthenogenetic. Originally described as a subgenus for four species, it now contains around 161 species.
The marbled crayfish or Marmorkrebs (Procambarus virginalis) is a parthenogenetic crayfish that was discovered in the pet trade in Germany in 1995. [4] [5] Marbled crayfish are closely related to the "slough crayfish", Procambarus fallax, [6] which is widely distributed across Florida. [7] No natural populations of marbled crayfish are known.

Procambarus zonangulus, the white river crawfish, [4] white river crayfish [5] or southern white river crayfish, [1] [6] is a species of freshwater crayfish. It is a distinct but closely related species from Procambarus acutus , which is also known as white river crayfish and has a wider range.
From this, it can be inferred that the crayfish spends most its time moving very slowly, or not at all, to conserve energy. Since food is scarce in this environment and there are few opportunities to feed, these crayfish are likely very opportunistic foragers. [5] Other than this, little is known about the behaviour of C. zophonastes. To better ...
