Crangonyx hobbsi

Unknown

Overview

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

Crangonyx hobbsi faces significant threats from groundwater pollution and habitat degradation within its limited cave and spring systems. Urban development and agricultural runoff in the surrounding watershed directly impact the water quality of the underground aquifers this amphipod depends upon. The species' restricted distribution to specific groundwater habitats makes it particularly vulnerable to localized contamination events and hydrological changes from surface activities.

Threat summary

Habitat

Crangonyx hobbsi inhabits underground freshwater systems including caves, springs, and groundwater aquifers in limestone karst regions. This subterranean amphipod is adapted to the stable, dark conditions of these groundwater environments where it feeds on organic matter and detritus.
