Hypsolebias multiradiatus

Declining

Overview

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

Hypsolebias multiradiatus 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 pools.
Threat summary

Habitat

This annual killifish inhabits temporary pools, seasonal ponds, and ephemeral water bodies in the Brazilian Cerrado savanna. The species requires shallow, vegetated pools that form during the rainy season and dry completely during drought periods, allowing eggs to survive in the substrate until the next flooding cycle.
