Hypsolebias janaubensis

Declining

Overview

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

Hypsolebias janaubensis faces severe threats from habitat destruction and water pollution in its extremely limited range. The species is restricted to temporary pools and wetlands that are increasingly being drained for agricultural development and urban expansion. Water contamination from agricultural runoff and domestic waste further degrades the quality of remaining breeding habitats, while the seasonal nature of these pools makes the species particularly vulnerable to drought and climate variability.

Threat summary

Habitat

This critically endangered killifish inhabits temporary pools, seasonal wetlands, and shallow water bodies in the Brazilian Cerrado savanna. The species depends on ephemeral aquatic habitats that fill during rainy seasons and may dry completely during drought periods.
