Overview

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

Allocrangonyx pellucidus faces severe threats from groundwater contamination and aquifer depletion throughout its limited range in the southeastern United States. Agricultural runoff, urban development, and industrial activities have degraded the pristine groundwater systems this species requires. Climate change poses additional risks through altered precipitation patterns that could affect groundwater recharge rates and cave hydrology.
