Palaemonetes mexicanus
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Palaemonetes mexicanus faces severe population decline due to groundwater depletion and aquifer contamination in its limited range within the Edwards Aquifer system of Texas. Agricultural runoff and urban development have degraded water quality in the springs and caves where this endemic freshwater shrimp survives. The species' extremely restricted distribution makes it highly vulnerable to any localized environmental changes or pollution events.
Habitat
This endemic freshwater shrimp inhabits springs, caves, and underground aquifer systems within the Edwards Aquifer region of south-central Texas. It requires clean, oxygen-rich groundwater with stable temperatures and specific mineral compositions typical of limestone karst environments.
