Barbudo negro
Batrochoglanis transmontanus
Overview
Barbudo negro (Batrochoglanis transmontanus) is a freshwater catfish species endemic to South American river systems, characterized by its dark coloration and barbels that give it its common name meaning 'black bearded one.' This benthic species plays an important ecological role as both predator and scavenger in riverine ecosystems, feeding on invertebrates and organic matter along the substrate.
Barbudo negro faces significant threats from habitat degradation and water pollution in its native South American river systems. Dam construction and agricultural runoff have altered water quality and flow patterns in the freshwater environments this catfish depends on for survival and reproduction.
Habitat
This freshwater catfish inhabits river systems and tributaries in the Amazon and Orinoco basins, typically found in areas with moderate to fast-flowing waters over sandy or rocky substrates. The species prefers well-oxygenated waters in both main river channels and smaller tributary streams.
