Elimia acuta

Unknown

Overview

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

Elimia acuta faces severe population declines primarily due to water pollution from agricultural runoff and urban development in its Tennessee River basin habitat. Dam construction has altered natural flow regimes and water chemistry, while sedimentation from land-use changes has degraded the rocky substrates essential for this freshwater snail's survival. Invasive zebra mussels compete for resources and alter ecosystem dynamics in some portions of its range.

Threat summary

Habitat

Elimia acuta inhabits fast-flowing, well-oxygenated streams and rivers with rocky or gravel substrates in the Tennessee River drainage system. This freshwater gastropod requires clean water with stable temperatures and specific calcium levels for shell development.

Why is Elimia acuta classified as Vulnerable?
Elimia acuta is classified as Vulnerable because the population is declining and the species faces a high risk of extinction in the medium-term future if current pressures continue. Elimia acuta faces severe population declines primarily due to water pollution from agricultural runoff and urban development in its Tennessee River basin habitat. Dam construction has altered natural flow regimes and water chemistry, while sedimentation from land-use changes has degraded the rocky substrates essential for this freshwater snail's survival. Invasive zebra mussels compete for resources and alter ecosystem dynamics in some portions of its range.
Where does Elimia acuta live?
Elimia acuta occurs in Canada, Jamaica, Philippines, and United States. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Elimia acuta?
The main threats to Elimia acuta are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
