Description
The banjo catfish is a remarkable South American catfish of the banjo catfish family (Aspredinidae) from the north of the continent. The species grows to about 32 cm and has a strongly flattened forebody with a broad head and a long, thin tail, making it resemble a banjo; the rough skin provides camouflage on the bottom. It lives mainly in brackish water on soft bottoms of shallow, turbid water near river mouths. As a bottom searcher it feeds on small invertebrates and detritus. Notably the female carries the fertilised eggs on the underside of her body. The stout pectoral spines can prick; otherwise it is harmless to humans.
