Hypsolebias delucai

Unknown

Overview

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

Hypsolebias delucai faces severe threats from habitat degradation in its restricted range within Brazil's Cerrado savanna. The species' dependence on temporary pools makes it particularly vulnerable to agricultural expansion and cattle ranching, which alter natural water flow patterns and contaminate breeding sites with sediments and chemicals. Climate change poses an additional threat by disrupting the seasonal rainfall patterns essential for the formation and maintenance of the temporary pools where this killifish completes its life cycle.
Threat summary

Habitat

This annual killifish inhabits temporary pools and seasonal wetlands in the Brazilian Cerrado savanna, where it has adapted to complete its entire life cycle within the brief wet season. The species depends on ephemeral water bodies that form during the rainy season and dry completely during the dry months, requiring specialized breeding strategies to survive in these harsh conditions.
