Stygobromus cooperi

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Stygobromus cooperi faces significant threats from groundwater depletion and contamination in its limited range within the Edwards Aquifer system of Texas. Urban development and agricultural activities above its subterranean habitat pose risks through altered hydrology and potential chemical pollution. The species' extreme habitat specialization and restricted distribution make it particularly vulnerable to any changes in groundwater quality or quantity.

Threat summary

Habitat

This species inhabits the phreatic zone of the Edwards Aquifer in south-central Texas, living in groundwater-filled limestone caves and associated subterranean water systems. It requires clean, oxygen-rich groundwater with stable temperatures and specific hydrochemical conditions typical of karst aquifer environments.
