Hypsolebias adornatus

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Hypsolebias adornatus 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 caused by 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.
