Campellolebias intermedius

Declining

Overview

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

Campellolebias intermedius faces severe threats from urban development and agricultural expansion that destroy its specialized seasonal pool habitats in Brazil's Atlantic Forest region. Water pollution from agricultural runoff and urban waste further degrades the temporary wetlands this killifish depends on for breeding. Climate change poses an additional risk by altering precipitation patterns that could disrupt the seasonal flooding cycles essential for the species' reproductive success.

Threat summary

Habitat

This killifish inhabits temporary seasonal pools and shallow wetlands in Brazil's Atlantic Forest region that fill during rainy seasons and dry completely during drought periods. The species has adapted to these ephemeral aquatic environments, completing its entire life cycle within the brief periods when water is present.
