Description

The knight catfish is a long-whiskered catfish (Pimelodidae) from fresh water of the Amazon and Orinoco basins in South America. The species grows to about 20 cm and has a slender, silver-grey body with long barbels, large eyes and a deeply forked tail. As a bottom-dweller it roots in sand and mud bottoms of rivers for insect larvae, small crustaceans and small fish. The stout, sharp dorsal and pectoral spines can give a painful puncture wound when handled.
