Campellolebias chrysolineatus
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Campellolebias chrysolineatus faces severe threats from urban expansion and agricultural development in its restricted coastal range near Rio de Janeiro, Brazil. The species' extremely limited distribution makes it particularly vulnerable to habitat destruction, with remaining populations confined to small, fragmented wetland areas. Water pollution from urban runoff and agricultural chemicals further degrades the shallow freshwater habitats essential for this killifish's survival.
Habitat
This critically endangered killifish inhabits shallow freshwater pools, temporary wetlands, and slow-moving streams in coastal lowland areas of southeastern Brazil. The species requires well-vegetated aquatic environments with soft substrates and is adapted to seasonal water level fluctuations in its native wetland systems.
