Somatogyrus tennesseensis

Unknown

Overview

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

Somatogyrus tennesseensis faces severe threats from water pollution and habitat degradation in Tennessee's spring systems. Dam construction and groundwater extraction have altered natural flow regimes, while agricultural runoff and urban development introduce harmful chemicals and sediments into its fragile aquatic environment. The species' extremely limited range makes it particularly vulnerable to any localized environmental disturbance.

Threat summary

Habitat

This freshwater gastropod inhabits spring-fed streams and seeps in Tennessee, requiring clean, well-oxygenated water with stable temperatures and consistent flow. It typically occurs in areas with limestone substrates where groundwater emerges, creating the specialized microhabitats essential for its survival.
