Description

The mountain catfish is a primitive catfish (Nematogenyidae) endemic to clear, cool rivers of central Chile in South America. The species grows to about 40 cm and has an elongate, smooth, yellow-brown, scaleless body with barbels. As a nocturnal bottom-dweller it shelters by day among stones and roots and searches for insect larvae and small invertebrates at night. Through habitat loss the species is vulnerable. The fish is harmless to humans.
