Opisthostoma fraternum
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Opisthostoma fraternum faces severe threats from limestone quarrying and mining activities that directly destroy its specialized cave and karst habitats. The species' extremely restricted range makes it particularly vulnerable to habitat modification, as even small-scale disturbances can eliminate entire populations. Agricultural expansion and urban development in surrounding areas further fragment the remaining suitable habitat.
Habitat
This micro-endemic land snail inhabits limestone caves and karst formations in tropical Southeast Asia. It requires specific microhabitat conditions within cave systems, including stable humidity and temperature regimes found in limestone crevices and cave entrances.
