Rhysoconcha variumbilicata

Unknown

Overview

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

Rhysoconcha variumbilicata faces severe threats from habitat destruction due to limestone quarrying and urban development in its restricted range. The species' dependence on specific microhabitat conditions within cave systems makes it extremely vulnerable to hydrological changes and pollution from surface activities. Its limited dispersal ability and small population size compound these pressures, leaving little resilience against environmental disturbances.

Threat summary

Habitat

This critically endangered land snail is endemic to limestone cave systems and associated karst formations in a highly restricted geographic range. It requires specific microhabitat conditions including stable moisture levels, particular substrate composition, and minimal light penetration found in deep cave environments.

Why is Rhysoconcha variumbilicata classified as Critically Endangered?
Rhysoconcha variumbilicata is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Rhysoconcha variumbilicata faces severe threats from habitat destruction due to limestone quarrying and urban development in its restricted range. The species' dependence on specific microhabitat conditions within cave systems makes it extremely vulnerable to hydrological changes and pollution from surface activities. Its limited dispersal ability and small population size compound these pressures, leaving little resilience against environmental disturbances.
Where does Rhysoconcha variumbilicata live?
Rhysoconcha variumbilicata occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
