Habitat and Ecology [top]
Habitat and Ecology: A semi-terrestrial species, which can be found under rocks in damp areas, up to many metres away from the stream. Most common under large rocks in wet areas adjacent to the stream. Nocturnal in habit and is probably omnivorous.
Found in the rugged mountain areas with the headwaters of the rivers draining the central highlands.
Systems: Freshwater
Threats [top]
Major Threat(s): Part of this species range is in a protected area, but in the lower reaches there is water pollution, habitat loss/degradation and uncontrolled tourism (viz. increased land use and over-exploitation of limited freshwater resources) which is a concern. In particular there is tourist swimming and playing in streams; alteration of stream course and reduced discharge due to water being piped to beach resorts. Some areas where crabs previously occurred have been altered or lost, e.g. stream flow altered or stream has dried up.
Conservation Actions [top]
Conservation Actions: Upper reaches of catchment where it is found are within a protected area.
Conservation of Pulau Tioman hinterland and monitoring of water usage from lower reaches of streams.
