Genera

Cambaridae is the largest of the three families of freshwater crayfish. Most of the species in the family are native to North America east of the Great Divide, such as the invasive Procambarus clarkii, with fewer species living in East Asia and Japan, such as zarigani (Cambaroides japonicus).

A recent molecular study<ref name=Braband>Braband et al. (2006). "The phylogenetic position of the East Asian freshwater crayfish Cambaroides within the Northern Hemisphere Astacoidea (Crustacea, Decapoda, Astacida) based on molecular data". Journal of Zoological Systematics 44 (1): 17–24.</ref> suggested that the family Cambaridae may be paraphyletic, with the family Astacidae nested within it. The status of the genus Cambaroides remains unclear.
