Description

The Andean pencil catfish is a small, slender catfish from high-altitude lakes and streams of the Andes, in western Bolivia, Peru and northern Chile, including Lakes Titicaca and Poopo. The species grows to about 37 cm and has a scaleless, mottled brown body with small eyes and a flattened head. As a bottom-dweller it shelters under stones by day and hunts small bottom animals at night. Unlike the notorious candiru this is not a blood-sucking parasite. The fish is harmless to humans and is assessed as Least Concern (LC) by the IUCN.
