Description

The black ripsaw catfish is a large thorny catfish (Doradidae) from the Amazon and Orinoco basins of South America. The species grows to about 1 metre and has a heavy, dark-grey to black body with a row of bony, saw-like side plates and three pairs of barbels. As a bottom-oriented omnivore it searches sand and mud bottoms of large rivers for detritus, invertebrates and plant material. It is an important food fish. The fish is harmless to humans, though the side plates and fin spines can graze.
