This species ranges from the drainage systems of the Cauca and Magdalena rivers in western and northern Colombia to the general vicinity of Lake Maracaibo Basin in Venezuela. It occurs up to 1,000m asl. Suggestions of its occurrence in the Orinoco River, and from Trinidad require confirmation, and are not included here.
Habitat and Ecology
It is an aquatic species, living in rivers, marshes and lakes, usually in open areas, and is only rarely found on land. It is thrives in polluted water, and is resilient to major degradation of water quality. It is oviviparous, giving birth to young in water.
It is a very common species.
It is extremely resilient to habitat and degradation and pollution, both of which are extensive within its range. It is popular in the international pet trade, but not at a level to constitute a threat to the species.
It occurs in some protected areas.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, tolerance of significant habitat degradation, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
