Melanorivulus crixas
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Melanorivulus crixas faces severe pressure from agricultural expansion and cattle ranching activities that degrade and fragment its wetland habitats in the Brazilian Cerrado. Water pollution from agricultural runoff containing pesticides and fertilizers poses an additional threat to this small killifish. The species' restricted range makes it particularly vulnerable to localized habitat destruction and water quality degradation.
Habitat
This small killifish inhabits shallow freshwater environments including temporary pools, small streams, and seasonal wetlands within the Cerrado savanna ecosystem of central Brazil. The species is adapted to waters with fluctuating levels and relies on interconnected aquatic habitats for breeding and survival.
