Parathelphusa cabayugan

Stable

Overview

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

Parathelphusa cabayugan faces severe pressure from habitat degradation in its limited freshwater cave systems in the Philippines. Mining activities and quarrying operations directly threaten the karst limestone formations that house this species' specialized cave habitats. Water pollution from agricultural runoff and domestic waste further compromises the delicate aquatic ecosystems these crabs depend upon for survival.
