Cambaridae is the largest of the three families of freshwater crayfish, with over 400 species. 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).
