Description

The sturgeon thorny catfish is a thorny catfish (Doradidae) from large rivers of the Amazon basin in South America. The species grows to about 20 cm and has an elongate, silver-grey body with a pointed, slightly sturgeon-like snout, long fringed barbels and a row of bony, thorned plates along the flank. As a nocturnal bottom-dweller it sifts over sand and mud for insect larvae, small crustaceans and detritus. The stout, serrated pectoral and dorsal spines can give a painful puncture wound when handled.
