Creagrutus varii

Unknown

Overview

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

Creagrutus varii faces significant pressure from deforestation and agricultural expansion throughout its limited range in the Amazon basin. Water pollution from mining activities and agricultural runoff poses additional risks to this freshwater species. The construction of small-scale dams and water diversions for irrigation further fragments its riverine habitat, while overfishing in some areas may impact local populations.

Threat summary
