Description

Hancock's talking catfish is a thorny catfish (Doradidae) from South America. The species has a stocky, dark body with pale lengthwise bands, barbels and a row of bony thorn plates along the flank, plus very stout, serrated pectoral fin spines. With these spines and its swim bladder it can produce grunting sounds, to which the name refers. It lives in quiet, shaded parts of blackwater and clearwater rivers of the Guiana Shield. Probing the bottom, it feeds on insect larvae, small invertebrates and detritus. The serrated fin spines can give a painful puncture wound.
