Aquadulcaris pheronyx

Unknown

Overview

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

Aquadulcaris pheronyx faces severe threats from groundwater extraction and pollution in its highly restricted freshwater habitat. The species' extremely limited distribution makes it particularly vulnerable to local environmental changes, with agricultural runoff and urban development degrading water quality in its few known locations. Climate change poses additional risks through altered precipitation patterns that could affect groundwater levels critical to this aquatic crustacean's survival.
Threat summary

Habitat
