Garcialebias nigrofasciatus
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Garcialebias nigrofasciatus faces severe threats from habitat destruction as temporary pools and wetlands in its restricted range are drained for agricultural expansion and urban development. The species' dependence on seasonal water bodies makes it extremely vulnerable to altered precipitation patterns and extended drought periods. Water pollution from agricultural runoff and livestock contamination further degrades the quality of remaining breeding habitats.
Habitat
This annual killifish inhabits temporary pools, seasonal wetlands, and shallow water bodies in coastal lowlands of Uruguay. The species requires ephemeral aquatic environments that fill during rainy seasons and dry completely during drought periods, completing its entire life cycle within these temporary habitats.
