An illustrated checklist of the American Crayfishes (Decapoda: Astacidae, Cambaridae
, and Parastacidae).
They also share some biological characteristics of all freshwater astacids (Families Astacidae, Cambaridae
and Parastacidae) such as: low fecundity, direct development with hatching in the juvenile stage, extended parental care up to the second juvenile stage, as well as omnivorous feeding habits (Rudolph & Rojas, 2003; Rudolph, 2013).
Male crayfish of the family Cambaridae
(including all Tennessee species) exhibit a cycle of dimorphism in which they alternate from a reproductively active stale in which their gonads have longer, more pointed terminal elements (form I) to a reproductively inactive state in which the gonads have shorter, more blunt terminal elements (form II) (Taylor and Schuster.
These studies suggest that the ranges of chromosome number in freshwater crayfish families (Astacidae, Cambaridae
, and Parastacidae) are larger than that reported for palaemonoid prawn (Table 2).
