Hypsolebias harmonicus
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Hypsolebias harmonicus faces severe threats from habitat degradation in Brazil's Cerrado savanna, where agricultural expansion and cattle ranching have fragmented its seasonal pool habitats. The species' dependence on temporary water bodies makes it particularly vulnerable to altered precipitation patterns and water table changes caused by land use conversion. Urban development and infrastructure projects further reduce available breeding sites in its limited range.
Habitat
This annual killifish inhabits temporary seasonal pools and shallow wetlands in the Brazilian Cerrado savanna. The species requires ephemeral water bodies that fill during rainy seasons and dry completely during drought periods, allowing their drought-resistant eggs to survive in the substrate.
