Trichomycterus arleoi
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Trichomycterus arleoi faces severe threats from habitat degradation in its restricted Andean range. Mining activities and agricultural expansion have altered water chemistry and sedimentation patterns in the high-altitude streams this catfish depends upon. Climate change poses additional risks through altered precipitation patterns and temperature increases that could push this cold-water specialist beyond its thermal tolerance limits.
Habitat
This endemic catfish inhabits cold, fast-flowing mountain streams and rivers in the high Andes of Peru. It typically occurs in well-oxygenated waters with rocky substrates at elevations between 3,000-4,200 meters above sea level.
