Habitat and Ecology [top]
Habitat and Ecology: Was found in a number of rather diverse habitats, all in the Batuan region in the centre of Bohol. Found in a garden well as well as in caves. Bonugan is one of a chain of caves along the same brook. The substrate of this stream is only moderately enriched with organic matter and the surface fauna is present only in the entrance. In Kalumpan the crab was found in an illuminated siphon pool which had no direct connection with any surface stream.
Systems: Freshwater
Threats [top]
Major Threat(s): Human disturbance of the biota is not as severe in Bonogan as in Ughab cave, e.g. bathing, laundry, swimming. The irrigation system of Eastern Batuan uses the caves for faster irrigation during harvest time (Urich (1991) from Proceedings of the international conference on environmental changes in the Karst Areas). Major threats are an irrigation system and the human use of these caves.
