Colligyrus depressus
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Colligyrus depressus faces significant pressure from habitat degradation in its limited range within Southeast Asian limestone karst formations. The species is particularly vulnerable to quarrying activities and cave disturbance, which directly destroy the specialized microhabitats required for its survival. Agricultural expansion and urban development in surrounding areas further fragment its already restricted habitat, while pollution from agricultural runoff may be affecting the delicate chemical balance of its cave and karst environments.
Habitat
This species inhabits limestone karst formations and associated cave systems in Southeast Asia, requiring the specific microclimate conditions found in these geologically distinct environments. It is typically found in areas where limestone bedrock creates complex underground networks and specialized surface features that support unique ecological communities.
