Elimia teres

Unknown

Overview

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

Elimia teres faces significant pressure from habitat degradation in its freshwater stream environments, particularly from sedimentation and pollution runoff that affects water quality. Dam construction and water diversions have altered natural flow regimes in many Tennessee River tributaries where this species occurs. Agricultural and urban development in surrounding watersheds continues to introduce contaminants and excess nutrients that degrade the clean, well-oxygenated waters this snail requires.

Threat summary

Habitat

Elimia teres inhabits clean, flowing freshwater streams and rivers in the Tennessee River drainage system, typically found on rocky substrates in well-oxygenated waters. This aquatic gastropod requires stable stream environments with minimal sedimentation and good water quality to support its filter-feeding lifestyle.
