Diplommatina gibboni

Unknown

Overview

Diplommatina gibboni s a species of land snail with an operculum, terrestrial gastropod mollusc in the family Diplommatinidae.

Diplommatina gibboni faces severe threats from limestone quarrying and cave disturbance in its restricted range in Peninsular Malaysia. The species' dependence on specific microhabitat conditions within limestone cave systems makes it extremely vulnerable to any alterations in cave structure or hydrology. Urban development and infrastructure projects in the karst landscape further fragment its already limited habitat, while pollution from nearby agricultural and industrial activities may alter the delicate chemical balance of its cave environment.

Threat summary

Habitat

This minute land snail inhabits limestone cave systems and karst formations in Peninsular Malaysia, typically found in the humid microenvironments near cave entrances and within shallow cave chambers. The species requires specific moisture levels and calcium-rich substrates provided by the limestone geology.

Frequently asked questions

Why is Diplommatina gibboni classified as Critically Endangered?
Diplommatina gibboni is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Diplommatina gibboni faces severe threats from limestone quarrying and cave disturbance in its restricted range in Peninsular Malaysia. The species' dependence on specific microhabitat conditions within limestone cave systems makes it extremely vulnerable to any alterations in cave structure or hydrology. Urban development and infrastructure projects in the karst landscape further fragment its already limited habitat, while pollution from nearby agricultural and industrial activities may alter the delicate chemical balance of its cave environment.
Where does Diplommatina gibboni live?
Diplommatina gibboni occurs in Palau. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Diplommatina gibboni?
The main threats to Diplommatina gibboni are 6.2, ai-1, ai-2, and ai-3. The full IUCN-classified threat record for this species is detailed on the species page.
