Opisthostoma decrespignyi
Overview
Opisthostoma decrespignyi 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 decrespignyi faces severe threats from limestone quarrying and mining activities that directly destroy its specialized cave and karst habitat. The species' extremely restricted range on Borneo makes it particularly vulnerable to habitat fragmentation, while its dependence on specific microhabitat conditions within limestone formations means even small-scale disturbances can eliminate entire populations. Agricultural expansion and infrastructure development in the surrounding landscape further isolate remaining habitat patches.
Habitat
This critically endangered land snail is endemic to limestone karst formations and cave systems in Borneo, where it inhabits the specialized microenvironments of rock crevices and cave entrances. The species requires specific humidity and temperature conditions found only within these limestone formations, making it entirely dependent on the integrity of karst ecosystems.
