Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Pleurocera corpulenta faces severe threats from habitat degradation and water quality deterioration in its limited freshwater stream systems. Dam construction and water diversions have altered natural flow regimes critical for this species' survival, while agricultural runoff and urban development have introduced pollutants that compromise water chemistry. The species' extremely restricted range makes it particularly vulnerable to localized environmental changes, with entire populations at risk from single disturbance events.
Habitat
This freshwater gastropod inhabits clean, well-oxygenated streams and rivers with rocky or gravel substrates in the southeastern United States. The species requires stable water chemistry and consistent flow patterns, typically found in headwater streams and spring-fed systems with minimal human disturbance.
