Hypselostoma megaphonum

Stable

Overview

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

Hypselostoma megaphonum faces severe threats from limestone quarrying and mining activities that directly destroy its cave habitat in the karst landscapes of Southeast Asia. Urban development and infrastructure expansion in the region continue to fragment and eliminate the specialized cave systems this species requires. Agricultural intensification and associated chemical runoff may alter the delicate microhabitat conditions within caves, affecting both the snail and its food sources.

Threat summary

Habitat

This species inhabits limestone caves and karst formations in tropical Southeast Asia, requiring the stable temperature and humidity conditions found in deep cave systems. It occupies specific microhabitats within caves where calcium carbonate deposits and organic matter accumulate.
