Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Crenicichla urosema faces severe pressure from habitat degradation in the Tocantins River basin, where dam construction and water diversions have altered natural flow regimes essential for this cichlid's reproductive cycles. Agricultural runoff and mining activities contribute significant pollution loads, while deforestation in the watershed increases sedimentation that degrades the rocky substrates this species requires for feeding and shelter.
Habitat
This endemic cichlid inhabits rocky areas and rapids in the Tocantins River system of central Brazil, preferring clear, fast-flowing waters with abundant stone crevices and boulder formations. The species is typically found in shallow to moderate depths where strong currents provide high oxygen levels and rocky substrates support diverse invertebrate prey communities.
