 Description
 
  This species grows to a length of 70 centimetres (28 in) TL and to a weight of 6.5 kilograms (14 lb). The colour pattern of these catfish varies depending upon the location that they originate from, though they are usually a muddy-brown colour with some darker spots over the body and fins. Adults are darker and the spotting fades from juvenile coloration. There are no scales, but the skin is thick and tough; also, 23–28 shallow lateral plates known as scutes are found along the length of the body. Their eyes are very small in comparison to the rest of the fish and they have three simple pairs of barbels. They have a deeply forked caudal fin, which also helps to distinguish this fish from other large Doradids.
