Description

The couma sea catfish is a large sea catfish of the family Ariidae reaching about 97 cm. The sturdy, silvery-grey body has barbels around the inferior mouth, an adipose fin and a deeply forked tail. The pectoral and dorsal fins bear stout spines armed with venom that can cause a painful, burning wound. The species lives on muddy bottoms of coastal waters, estuaries and river mouths along northeastern South America and tolerates brackish water. On the bottom it hunts crustaceans, molluscs, worms and small fish. Like many sea catfishes it is a mouthbrooder: the male broods the strikingly large eggs in his mouth. With its tasty flesh it is a valued food fish; care with the venomous spines is needed when handling.
