Hypsolebias guanambi
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Hypsolebias guanambi faces severe threats from habitat degradation in Brazil's Caatinga region, where seasonal pools essential for its reproduction are increasingly impacted by agricultural expansion and water extraction. The species' extremely restricted range makes it particularly vulnerable to local environmental changes, while prolonged droughts associated with climate variability threaten the temporary water bodies this killifish depends upon for breeding.
Habitat
This annual killifish inhabits temporary pools and seasonal wetlands in the semi-arid Caatinga scrubland of northeastern Brazil. The species depends entirely on ephemeral water bodies that form during the rainy season and dry completely during drought periods.
