Pogonopoma parahybae
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Pogonopoma parahybae faces severe pressure from dam construction and water diversions throughout the Paraíba do Sul River basin, which fragment populations and alter natural flow regimes essential for reproduction. Agricultural runoff and urban pollution have degraded water quality in many tributaries, while sand mining operations directly destroy benthic habitats where this armored catfish feeds and shelters. The species' restricted range within southeastern Brazil's heavily developed river systems makes it particularly vulnerable to cumulative anthropogenic impacts.
Habitat
This endemic armored catfish inhabits rocky substrates and fast-flowing sections of the Paraíba do Sul River system in southeastern Brazil. It prefers well-oxygenated waters with moderate to strong currents, typically found in riffles and rapids where it grazes on algae and organic matter attached to stones.
