Leptoxis picta

Unknown

Overview

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

Leptoxis picta faces severe population declines primarily due to dam construction and water diversions that alter natural flow regimes in its riverine habitats. Sedimentation from agricultural runoff and urban development degrades water quality and smothers the rocky substrates essential for feeding and reproduction. Pollution from industrial discharge and agricultural chemicals further compromises water quality in the Tennessee River system where this species occurs.

Threat summary

Habitat

This freshwater gastropod inhabits fast-flowing rivers and streams with rocky substrates in the Tennessee River drainage system. It requires well-oxygenated waters with stable flow regimes and clean gravel or boulder bottoms for feeding on periphyton and detritus.
