Diplommatina crassilabris

Unknown

Overview

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

Diplommatina crassilabris faces severe threats from habitat destruction and degradation of its limestone cave and karst environments. The species' extremely restricted range makes it particularly vulnerable to local disturbances, including quarrying activities, tourism development, and changes in groundwater hydrology that affect cave ecosystems. Climate change poses additional risks through altered precipitation patterns that could disrupt the delicate moisture balance essential for this cave-dwelling gastropod's survival.

Threat summary

Habitat

This species inhabits limestone caves and karst formations, typically found in humid cave environments with stable temperature and moisture conditions. It occupies the twilight zones of caves where organic matter accumulates, providing the detritus and biofilm on which it feeds.

Why is Diplommatina crassilabris classified as Critically Endangered?
Diplommatina crassilabris 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 crassilabris faces severe threats from habitat destruction and degradation of its limestone cave and karst environments. The species' extremely restricted range makes it particularly vulnerable to local disturbances, including quarrying activities, tourism development, and changes in groundwater hydrology that affect cave ecosystems. Climate change poses additional risks through altered precipitation patterns that could disrupt the delicate moisture balance essential for this cave-dwelling gastropod's survival.
Where does Diplommatina crassilabris live?
Diplommatina crassilabris occurs in Palau. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
