Leptoxis praerosa
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Leptoxis praerosa faces severe population declines primarily due to dam construction and water impoundment throughout its Tennessee River system range. Sedimentation from agricultural runoff and urban development has degraded the rocky substrates essential for this freshwater gastropod's survival. Water quality deterioration from industrial pollution and altered flow regimes have further compromised remaining populations in Alabama and Tennessee river systems.
Habitat
This freshwater snail inhabits rocky substrates in fast-flowing rivers and streams within the Tennessee River drainage system. It requires well-oxygenated waters with stable rocky or gravel bottoms where it can graze on periphyton and organic matter.
