Leptoxis virgata

Unknown

Overview

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

Leptoxis virgata faces severe population declines primarily due to dam construction and water diversions that have altered natural flow regimes in Tennessee River tributaries. Sedimentation from agricultural runoff and urban development has degraded water quality and smothered critical substrate habitats. Industrial pollution and mining activities have further compromised water chemistry in key watersheds where this freshwater gastropod historically thrived.

Threat summary

Habitat

This freshwater snail inhabits rocky substrates in fast-flowing streams and rivers within the Tennessee River drainage system. It requires well-oxygenated waters with stable flow patterns and clean gravel or cobble bottoms for feeding and reproduction.
