Marstonia castor
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Marstonia castor faces severe threats from groundwater depletion and contamination in its limited spring habitat range. Urban development and agricultural runoff have degraded water quality in the few remaining springs where this species persists. The species' extremely restricted distribution makes it particularly vulnerable to localized environmental changes and pollution events.
Habitat
This freshwater gastropod is endemic to limestone springs and spring-fed streams in the southeastern United States. It requires clean, well-oxygenated groundwater with stable temperatures and specific mineral compositions typical of karst spring systems.
