Stygobromus heteropodus

Unknown

Overview

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

Stygobromus heteropodus faces primary 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 surface activities. Water table lowering from excessive pumping further reduces available habitat in the already restricted cave and spring systems where this amphipod occurs.

Threat summary

Habitat

This obligate groundwater amphipod inhabits cave streams, springs, and interstitial waters in karst limestone formations. The species requires pristine, oxygen-rich groundwater with stable temperatures and minimal chemical contamination.
