Hypsolebias longignatus

Unknown

Overview

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

Hypsolebias longignatus faces severe habitat degradation from agricultural expansion and cattle ranching in Brazil's Cerrado savanna. The species' restricted range in temporary pools makes it extremely vulnerable to drought intensification and water table changes from land conversion. Mining activities and urban development further fragment the already limited seasonal wetland habitats essential for this killifish's survival.

Threat summary

Habitat

This annual killifish inhabits temporary pools and seasonal wetlands in Brazil's Cerrado savanna region. The species depends on ephemeral water bodies that fill during rainy seasons and dry completely during drought periods, requiring specialized adaptations for survival in these highly variable aquatic environments.
