Ophthalmolebias bokermanni
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Ophthalmolebias bokermanni faces severe threats from habitat destruction due to agricultural expansion and urban development in its restricted range. The species' dependence on temporary pools makes it extremely vulnerable to hydrological changes from water extraction and climate variability. Its limited distribution and specialized breeding requirements in seasonal wetlands leave little room for population recovery when local habitats are degraded or destroyed.
Habitat
This annual killifish inhabits temporary pools and seasonal wetlands in the Brazilian Cerrado savanna. The species requires shallow, ephemeral water bodies that fill during the rainy season and dry completely during drought periods, allowing their drought-resistant eggs to survive in the substrate.
