Glandulocauda caerulea
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Glandulocauda caerulea faces severe pressure from deforestation and agricultural expansion throughout its limited range in southeastern Brazil's Atlantic Forest region. Urban development and water pollution from agricultural runoff have degraded the clear, fast-flowing streams this species requires for survival. The fragmentation of remaining forest patches has isolated populations, reducing genetic diversity and making recovery increasingly difficult.
Habitat
This small characin inhabits clear, fast-flowing streams and tributaries within the Atlantic Forest biome of southeastern Brazil. It prefers well-oxygenated waters with rocky or sandy substrates, typically found in forested headwater streams at elevations between 400-800 meters.
