Trichogenes claviger
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Trichogenes claviger faces severe threats from deforestation and agricultural expansion in its restricted Atlantic Forest range in southeastern Brazil. The species' extremely limited distribution makes it particularly vulnerable to habitat fragmentation, while water pollution from agricultural runoff and urban development degrades the pristine stream conditions this catfish requires. Climate change poses additional risks through altered precipitation patterns that could affect the delicate hydrological balance of its mountain stream ecosystems.
Habitat
Trichogenes claviger inhabits clear, fast-flowing mountain streams in the Atlantic Forest of southeastern Brazil, typically found in areas with rocky substrates and dense riparian vegetation. The species requires pristine water conditions and is associated with well-oxygenated streams at elevations between 800-1200 meters.
