Cambarus subterraneus

Unknown

Overview

Cambarus subterraneus, the Delaware County cave crayfish, is a species of crayfish in the family Cambaridae. It has been found only in three caves in Delaware County, Oklahoma.

Cambarus subterraneus faces severe threats from groundwater contamination and habitat degradation within its extremely limited cave system range. Agricultural runoff, urban development, and industrial activities in the surface watershed directly impact the delicate groundwater chemistry essential for this species' survival. The species' restriction to specific cave environments makes it particularly vulnerable to any changes in water quality or flow patterns.

Threat summary

Habitat

This species inhabits underground cave systems and associated groundwater environments in limestone karst regions. It requires pristine groundwater conditions with specific temperature, oxygen, and chemical parameters found only in undisturbed subterranean aquatic habitats.
