Hypsolebias fulminantis
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Hypsolebias fulminantis faces severe threats from habitat destruction as temporary pools in the Brazilian Cerrado are drained for agricultural expansion and cattle ranching. The species' dependence on seasonal water bodies makes it extremely vulnerable to drought intensification and altered precipitation patterns from climate change. Urban development and infrastructure projects further fragment the already limited suitable habitat, while water pollution from agricultural runoff degrades remaining breeding sites.
Habitat
This annual killifish inhabits temporary pools and seasonal wetlands in the Brazilian Cerrado savanna, particularly in areas with sandy soils that retain water during the rainy season. The species requires shallow, ephemeral water bodies that dry completely during the dry season, allowing eggs to survive in the substrate until the next rains.
