Stygobromus pizzinii
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Stygobromus pizzinii faces severe threats from groundwater contamination and aquifer depletion in its limited range within the Edwards Aquifer system of Texas. Urban development and agricultural activities above its subterranean habitat introduce pollutants and alter natural water flow patterns. The species' extreme habitat specialization and restricted distribution make it particularly vulnerable to any changes in groundwater quality or quantity.
Habitat
This obligate cave-dwelling amphipod inhabits the phreatic zone of the Edwards Aquifer system in south-central Texas, living in water-filled limestone caverns and underground streams. The species requires pristine groundwater conditions with stable temperatures and specific chemical compositions found only in these deep karst aquifer systems.
