Cambaridae is the largest of the three families of freshwater crayfish, with over 400 species [cite web |url=http://iz.carnegiemnh.org/crayfish/NewAstacidea/family.asp?f=Cambaridae |title=Family Cambaridae Hobbs, 1942 |work=Crayfish Taxon Browser |author=James W. Fetzner, Jr. |publisher=Carnegie Museum of Natural History |date=2005-05-09] . Most of the species in the family are native to North America east of the Great Divide, such as the invasive species "Procambarus clarkii" and "Orconectes rusticus", with fewer species living in East Asia and Japan, such as zarigani ("Cambaroides japonicus").

A recent molecular study cite journal | quotes=no |author =A. Braband, T. Kawai & G.
