Lucifuga teresinarum

Unknown

Overview

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

Lucifuga teresinarum faces severe threats from groundwater extraction and contamination in its limited cave habitat range in northeastern Brazil. Urban development and agricultural activities above the cave systems pose significant risks through altered hydrology and chemical runoff. The species' extremely restricted distribution makes it particularly vulnerable to any disturbance of its specialized subterranean aquatic environment.
