Microcondylaea bonellii

DecliningVUEUVUEU

Overview

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

Microcondylaea bonellii faces severe threats from water pollution and habitat degradation in its limited freshwater range. Dam construction and water extraction have altered natural flow regimes, while agricultural runoff and urban pollution have degraded water quality. The species' extremely restricted distribution makes it particularly vulnerable to localized environmental changes, with entire populations at risk from single pollution events.

Threat summary

Habitat

This freshwater mussel inhabits clean, well-oxygenated rivers and streams with sandy or gravelly substrates. It requires stable water flow and good water quality to filter-feed effectively and complete its complex reproductive cycle.
