Notopala sublineata
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Notopala sublineata faces severe population declines primarily due to water extraction and river regulation that reduces flow volumes in its freshwater habitats. Agricultural runoff and urban pollution have degraded water quality in many river systems where this species occurs. Introduced species, particularly exotic fish and other molluscs, compete for resources and may prey upon juvenile snails, further pressuring already fragmented populations.
Habitat
This freshwater gastropod inhabits slow-flowing rivers, streams, and permanent water bodies across southeastern Australia. It typically occurs in areas with sandy or muddy substrates and aquatic vegetation, preferring waters with stable flow regimes and good water quality.
