Description

The banjo catfish is a South American catfish of the banjo catfish family (Aspredinidae) from the north-eastern coast of South America. The species grows to about 38 cm and has a strongly flattened front and a long, thin tail, together shaped like a banjo, with a rough, tubercle-studded skin. It lives on sand and mud bottoms of brackish coastal waters and estuaries. As a bottom searcher it feeds on small invertebrates, worms and detritus. Notable is its brood care: the female carries the fertilised eggs attached to her belly. The fin spines can prick, so handle the fish with care.
