Trichomycterus belensis

**Bagre de torrente (Trichomycterus belensis)** The Bagre de torrente is a small freshwater catfish endemic to the Neotropical region. This species belongs to the pencil catfish family (Trichomycteridae), characterized by an elongated, scaleless body and reduced or absent pelvic fins. Like other members of its genus, T. belensis likely exhibits nocturnal behavior and feeds on small invertebrates and organic matter found in stream substrates. These catfish play important roles in freshwater ecosystems as both predators of smaller organisms and prey for larger fish and aquatic vertebrates. This species has an extremely restricted geographic range, found only in specific freshwater systems within the Neotropical region. The exact localities remain limited, contributing to its vulnerable status. Bagre de torrente inhabits fast-flowing streams and torrential waters, as suggested by its common name, preferring rocky substrates and well-oxygenated environments typical of montane or highland aquatic systems. The species faces critical endangerment, though specific threats have not been formally assessed by the IUCN. Given its restricted range and specialized habitat requirements, potential threats likely include habitat degradation from agricultural runoff, mining activities, dam construction, and climate change impacts on water flow patterns. The small population size and limited distribution make the species particularly vulnerable to environmental disturbances. Currently, no specific conservation measures for T. belensis have been documented. The population trend remains unknown, reflecting limited research and monitoring efforts. Without immediate attention to habitat protection and population assessment, the species' outlook remains precarious, with potential for further decline or local extinction.
