Declining

Overview

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

Campellolebias dorsimaculatus faces severe threats from urban expansion and agricultural development in its restricted coastal range in southeastern Brazil. The species' dependence on temporary seasonal pools makes it extremely vulnerable to habitat modification and water pollution from agricultural runoff. Climate change poses an additional threat through altered precipitation patterns that could disrupt the delicate timing of its breeding cycle tied to seasonal flooding.
