Melanopsis subgraellsiana
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Melanopsis subgraellsiana faces severe pressure from water extraction and dam construction that disrupts the natural flow regimes essential for its survival. Agricultural runoff and urban pollution have degraded water quality in many of its remaining habitats, while invasive species compete for resources and alter ecosystem dynamics. Climate change-induced droughts further stress already fragmented populations by reducing water levels in critical breeding areas.
Habitat
This freshwater gastropod inhabits slow-flowing rivers, streams, and associated wetlands in the Mediterranean basin, typically found in areas with rocky or sandy substrates. It requires clean, well-oxygenated water with stable flow patterns and is particularly sensitive to changes in water chemistry and temperature.
