Description

The giant sea catfish is a large sea catfish of the family Ariidae from the Indo-West Pacific. The species grows to about 1.85 metres and has a robust, silver-grey body with barbels around the mouth and an adipose fin. It is a marine species that often visits estuaries but rarely enters fresh water. As a bottom predator it feeds on fishes, crustaceans and molluscs. Like other sea catfishes it is a paternal mouthbrooder: the male broods the large eggs in its mouth. The stout, serrated pectoral and dorsal spines bear venom and can give a painful puncture wound; therefore handle the fish with care.
