Cnesterodon omorgmatos
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Cnesterodon omorgmatos faces severe threats from habitat degradation and water pollution in its restricted range within the Río de la Plata basin. Urban development and agricultural runoff have significantly altered water quality in the small streams and tributaries where this species occurs. The introduction of non-native fish species has created additional competitive pressure, while dam construction and water extraction have modified natural flow regimes essential for reproduction.
Habitat
This small freshwater fish inhabits shallow, slow-flowing streams and tributaries within the Río de la Plata drainage system in South America. It typically occurs in areas with dense aquatic vegetation and soft substrates, preferring waters with moderate temperatures and specific chemical parameters.
