Description
The Weddell's thorny catfish is a thorny catfish (Doradidae) from slow-flowing fresh water of the Amazon basin in South America. The species grows to about 13 cm and has a sturdy, dark body with a row of bony, thorned plates along the flank and strong barbels; by vibrating its swim bladder it makes a grunting sound. As a nocturnal bottom-dweller it shelters by day under wood and roots and searches at night for snails, insect larvae and detritus. The stout, serrated pectoral and dorsal spines can give a painful puncture wound when handled.
