Opisthostoma inornatum

Declining

Overview

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

Opisthostoma inornatum faces severe threats from limestone quarrying and mining 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 agricultural expansion and urban development in surrounding areas fragment remaining suitable habitat. Climate change poses additional risks through altered moisture regimes that could affect the delicate microhabitat conditions this cave-dwelling snail requires.

Threat summary

Habitat

This species inhabits limestone caves and karst formations in tropical rainforest areas of Peninsular Malaysia. It requires specific microhabitat conditions including stable humidity levels and calcium-rich substrates typical of cave environments.
