The Dougherty Plains Cave Crayfish, Cambarus cryptodytes, is an obligate inhabitant of groundwater. This species only lives in the Floridan Aquifer and is known from sites in both Florida and Georgia. Groundwater contamination threatens this species with intensive agricultural activities taking place on the surface above the Floridan Aquifer. As with all crayfish, females lay eggs, which are attached to the bottom of her tail. The eggs develop beneath the female's tail until they hatch. The babies remain beneath her tail for a week or two before dropping off and living alone. One difference between surface crayfish and cave crayfish is that cave crayfish likely don't breed each year and when they do, they have far fewer babies than surface species. There simply are not a lot of food resources in most subterranean waterways to support large populations of cave crayfish. These images were taken in Georgia in 2012.
