Mexistenasellus parzefalli

Unknown

Overview

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

Mexistenasellus parzefalli faces severe threats from groundwater extraction and contamination in its limited cave habitat range in northeastern Mexico. The species' dependence on stable groundwater levels makes it particularly vulnerable to aquifer depletion from agricultural and urban water demands. Pollution from agricultural runoff and urban development poses additional risks to the delicate cave ecosystem chemistry this endemic isopod requires.

Threat summary

Habitat

This species inhabits underground freshwater cave systems and associated groundwater networks in the karst regions of northeastern Mexico. It requires stable, unpolluted groundwater with specific temperature and chemical conditions typical of deep cave environments.
