Opisthostoma perspectivum

Declining

Overview

Opisthostoma perspectivum is a species of small land snail with an operculum, a terrestrial gastropod mollusc in the family Diplommatinidae. This species is endemic to Malaysia. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.

Opisthostoma perspectivum faces severe threats from limestone quarrying and mining activities that directly destroy its specialized cave and karst habitat. The species' extremely restricted range in Malaysian limestone formations makes it particularly vulnerable to habitat fragmentation and complete site destruction. Agricultural expansion and urban development in surrounding areas further compress its already limited habitat, while pollution from mining operations degrades the delicate cave ecosystems this endemic snail depends upon.

Threat summary

Habitat

This endemic Malaysian species inhabits limestone caves and karst formations, specifically dwelling in the humid microenvironments of cave entrances and crevices within limestone outcrops. It requires the stable temperature and moisture conditions found in these specialized geological formations.
