Overview

Stygobromus smithi, the Alabama well amphipod, is a phreatobite species of crustacean in family Crangonyctidae. It is endemic to Alabama in the United States.

The Alabama Well Amphipod faces significant threats from groundwater contamination and habitat degradation due to agricultural runoff, urban development, and industrial activities in its limited range. As a cave-dwelling species with extremely restricted distribution, it is particularly vulnerable to water quality changes and hydrological alterations that can rapidly impact its specialized subterranean ecosystem.
