VUVulnerable
Melanorivulus rubromarginatus
Unknown
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Melanorivulus rubromarginatus faces severe pressure from agricultural expansion and cattle ranching activities that degrade and fragment its freshwater habitats in Brazil's Cerrado region. Urban development and water extraction for irrigation further reduce available breeding sites, while pollution from agricultural runoff degrades water quality in remaining streams and seasonal pools.
Habitat
This killifish inhabits small freshwater streams, temporary pools, and seasonal wetlands within Brazil's Cerrado savanna ecosystem. It typically occurs in shallow, slow-moving waters with dense aquatic vegetation and soft substrates.
