Description

The Demerara thorny catfish is an armoured catfish from northern South America, known from the Essequibo, Demerara and Corantijn and possibly other coastal rivers to the mouth of the Amazon. It grows to about 35 cm and has a row of bony, hook-bearing plates along the flank, characteristic of the thorny catfishes. Around the mouth it carries barbels. A bottom-dweller, it searches tropical fresh water for food and eats mainly organic matter and small bottom animals. The fish is harmless to humans and is assessed as Least Concern (LC) by the IUCN.
