Freshwater Animal Diversity Assessment
Abstract The freshwater crayfishes are distributed across all but the Indian and Antarctic continents with centers of diversity in the southeastern Appalachian Mountains in the Northern Hemisphere and in south– east Australia in the Southern Hemisphere. There are currently over 640 described species...
