Paladilhiopsis tarae

DecliningDDEUDDEU

Overview

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

Paladilhiopsis tarae is a subterranean freshwater snail known only from a single spring or cave system, making it acutely vulnerable to any disturbance of its groundwater habitat. Local aquifer over-extraction for agriculture and domestic use threatens to lower water tables below the level required to sustain its habitat, while pollution from surface runoff can degrade water quality in these highly sensitive systems. Because the species has an extremely restricted range typical of stygobitic (groundwater-dwelling) mollusks, even localized hydrological changes pose a disproportionate extinction risk.

Threat summary

Habitat

This species inhabits groundwater-fed springs and subterranean freshwater systems, relying on stable, clean water conditions typical of karst or phreatic environments in its narrow geographic range.
