Stygobromus morrisoni
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Stygobromus morrisoni 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.
Habitat
This species inhabits the phreatic zone of the Edwards Aquifer in south-central Texas, living in water-filled caves and underground streams. It requires clean, oxygen-rich groundwater with stable temperatures and specific hydrochemical conditions typical of limestone karst aquifer systems.
