Threats

Major Threats
Due to the small nature of the streams in which the species occurs, it is likely that a good proportion of habitat remains intact enough to support this species. Even considering the extent of disturbance (heavy pollution and habitat degradation) in the Lake Maraciabo basin, the species is likely not to have suffered unduly. Creagrutus species are relatively resilient to habitat modification.
