Haplophthalmus rhinoceros

Unknown

Overview

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

Haplophthalmus rhinoceros faces significant pressure from habitat degradation in its specialized cave and underground environments. Urban development and quarrying activities directly destroy the limestone formations and cave systems essential for this species' survival. Agricultural intensification and groundwater extraction alter the moisture regimes and soil chemistry that these terrestrial isopods require, while pollution from surface activities can contaminate their sensitive subterranean habitats.

Threat summary

Habitat

This species inhabits limestone cave systems and associated underground environments in karst landscapes. It requires stable, humid conditions found in cave entrances, rock crevices, and the soil-cave interface zones where organic matter accumulates.
