Baryancistrus niveatus
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Baryancistrus niveatus faces severe pressure from dam construction and hydroelectric development along the Xingu River system, which fragments its habitat and alters critical water flow patterns. Mining activities and deforestation in the watershed contribute to increased sedimentation and water quality degradation. The species' restricted range within specific rapids and rocky substrates makes it particularly vulnerable to habitat modifications, with limited ability to colonize alternative areas.
Habitat
This armored catfish inhabits fast-flowing rocky rapids and boulder-strewn areas of the Xingu River basin in Brazil. It requires well-oxygenated waters with strong currents and complex rocky substrates that provide both feeding opportunities and shelter from predators.
