VU

Stygobromus indentatus

Unknown

Overview

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

Stygobromus indentatus faces severe threats from groundwater contamination and aquifer depletion due to agricultural runoff and urban development in its limited range. The species' obligate dependence on pristine groundwater systems makes it extremely vulnerable to pollution from pesticides, fertilizers, and industrial chemicals that can persist in aquifers for decades. Water table lowering from excessive pumping for irrigation and municipal use directly destroys its habitat by drying up the cave streams and springs where it lives.

Threat summary

Habitat

This obligate groundwater amphipod inhabits cave streams, springs, and interstitial waters in karst aquifer systems. It requires pristine, oxygen-rich groundwater with stable temperatures and minimal chemical contamination.
