Parathelphusa nagasakti
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Parathelphusa nagasakti faces severe pressure from habitat degradation in its limited freshwater range. Agricultural expansion and urban development have significantly reduced suitable stream and river habitats, while water pollution from agricultural runoff and domestic waste further compromises water quality. The species' restricted distribution makes it particularly vulnerable to localized environmental changes.
Habitat
This freshwater crab inhabits clean streams, rivers, and associated riparian areas in tropical Southeast Asian watersheds. It requires well-oxygenated water with rocky or sandy substrates and depends on intact forest cover for maintaining optimal water quality and temperature conditions.
