Overview

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

The mouse-eared snail faces severe population declines primarily due to coastal habitat destruction and modification of salt marsh environments. Rising sea levels and increased storm intensity associated with climate change threaten the delicate balance of its intertidal zone habitats. Pollution from agricultural runoff and urban development degrades the water quality of estuarine systems where this species depends on specific salinity levels and organic matter availability.

Threat summary

Habitat

The mouse-eared snail inhabits salt marshes, mudflats, and brackish water environments along temperate coastlines, particularly favoring areas with mixed salinity where freshwater meets marine systems. It requires specific microhabitats within the intertidal zone where organic detritus accumulates and salinity levels fluctuate with tidal cycles.

Frequently asked questions

Why is mouse-eared snail classified as Vulnerable?
mouse-eared snail 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. The mouse-eared snail faces severe population declines primarily due to coastal habitat destruction and modification of salt marsh environments. Rising sea levels and increased storm intensity associated with climate change threaten the delicate balance of its intertidal zone habitats. Pollution from agricultural runoff and urban development degrades the water quality of estuarine systems where this species depends on specific salinity levels and organic matter availability.
Where does mouse-eared snail live?
mouse-eared snail occurs in Algeria, Australia, Bahamas, Belgium, Bermuda, and Bosnia & Herzegovina (plus 39 other countries). Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to mouse-eared snail?
The main threats to mouse-eared snail 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.
