Glandulocauda caerulea

Declining

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.

Threat summary

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.

Frequently asked questions

Why is Glandulocauda caerulea classified as Endangered?
Glandulocauda caerulea is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. 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.
Where does Glandulocauda caerulea live?
Glandulocauda caerulea occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Glandulocauda caerulea?
The main threats to Glandulocauda caerulea are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
