Corumbataia britskii
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Corumbataia britskii faces severe pressure from habitat degradation in the Upper Paraná River basin, where agricultural expansion and cattle ranching have led to increased sedimentation and water quality deterioration. Dam construction and water diversions for irrigation have altered natural flow regimes critical for this bottom-dwelling catfish. The species' restricted range makes it particularly vulnerable to localized environmental changes, with pollution from agricultural runoff representing an ongoing threat to remaining populations.
Habitat
This small armored catfish inhabits rocky substrates and fast-flowing sections of tributaries in the Upper Paraná River system in Brazil. It prefers clear, well-oxygenated waters with moderate to strong currents, typically found among stones and gravel beds where it feeds on algae and small invertebrates.
