Yabby Cherax destructor, copyright Chameleon.

Belongs within: Astacidea.
Contains: Cambarus, Procambarus, Orconectes.

The Astacida are the freshwater crayfish. They are divisible between the Northern Hemisphere Astacoidea and the Southern Hemisphere Parastacidae (Martin & Davis 2001). In the Astacoidea, the first pleopod is well developed and used for sperm transfer in males but reduced or absent in females, whereas in Parastacidae it is absent in both sexes. Some species are commercially significant for food, such as the yabby Cherax destructor in Australia and the red swamp crayfish Procambarus clarkii in North America.

Synapomorphies (from Dixon et al. 2003): Gastrulation an invagination process showing a ring of about forty ectoteloblasts; development direct. Ischium-merus boundary of first pereiopod perpendicular; no median ridge or suture in posterior carapace; soft cuticle present in distal part of telson.
