Hypsolebias fasciatus
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Hypsolebias fasciatus faces severe habitat degradation from agricultural expansion and urban development across its limited range in Brazil's Atlantic Forest region. The species' dependence on temporary pools and seasonal wetlands makes it particularly vulnerable to hydrological changes from deforestation and water extraction. Climate change poses an additional threat by altering precipitation patterns that are critical for the breeding cycles of this annual killifish.
Habitat
This annual killifish inhabits temporary pools, seasonal wetlands, and shallow water bodies in Brazil's Atlantic Forest region. The species requires specific hydrological conditions with predictable wet-dry cycles for successful reproduction and egg development in substrate.
