Creagrutus crenatus

Unknown

Overview

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

Creagrutus crenatus faces severe population decline primarily due to deforestation and agricultural expansion within its limited range in the Amazon basin. Water pollution from mining activities and agricultural runoff has degraded stream quality in its headwater habitats. The species' restricted distribution makes it particularly vulnerable to localized environmental changes, with habitat fragmentation isolating remaining populations.

Threat summary

Habitat

This small characin fish inhabits clear, fast-flowing streams and tributaries in the upper Amazon basin, typically found in areas with rocky substrates and moderate current. It prefers well-oxygenated waters in forested watersheds at elevations between 200-800 meters.

Creagrutus crenatus 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. Creagrutus crenatus faces severe population decline primarily due to deforestation and agricultural expansion within its limited range in the Amazon basin. Water pollution from mining activities and agricultural runoff has degraded stream quality in its headwater habitats. The species' restricted distribution makes it particularly vulnerable to localized environmental changes, with habitat fragmentation isolating remaining populations.
Where does Creagrutus crenatus live?
Creagrutus crenatus occurs in Venezuela. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
