Opisthostoma mirabile

Declining

Overview

Opisthostoma mirabile is a species of air-breathing land snail with an operculum, a terrestrial gastropod mollusc in the family Diplommatinidae.

Opisthostoma mirabile faces severe threats from limestone quarrying activities that directly destroy its cave and karst habitat in Peninsular Malaysia. The species' extremely restricted range makes it particularly vulnerable to habitat modification, while its specialized cave-dwelling ecology limits dispersal to alternative sites. Climate change poses additional risks through altered humidity and temperature regimes within cave systems.

Threat summary

Habitat

This species inhabits limestone cave systems and karst formations in Peninsular Malaysia, specifically adapted to the humid, stable microclimate conditions found within cave environments. It requires the calcium-rich substrates and specialized ecological conditions that develop in tropical limestone cave ecosystems.

Frequently asked questions

Why is Opisthostoma mirabile classified as Critically Endangered?
Opisthostoma mirabile 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. Opisthostoma mirabile faces severe threats from limestone quarrying activities that directly destroy its cave and karst habitat in Peninsular Malaysia. The species' extremely restricted range makes it particularly vulnerable to habitat modification, while its specialized cave-dwelling ecology limits dispersal to alternative sites. Climate change poses additional risks through altered humidity and temperature regimes within cave systems.
Where does Opisthostoma mirabile live?
Opisthostoma mirabile occurs in Malaysia. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Opisthostoma mirabile?
The main threats to Opisthostoma mirabile are 3.2, 5.3, 7.1, and ai-1. The full IUCN-classified threat record for this species is detailed on the species page.
