Overview

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

Allocrangonyx hubrichti faces significant threats from groundwater contamination and habitat degradation within its limited cave and spring systems. Urban development and agricultural runoff in the surrounding watershed pose ongoing risks to water quality in the species' subterranean habitat. The amphipod's restricted range and specialized habitat requirements make it particularly vulnerable to localized environmental changes and pollution events.
