Description

The flathead sea catfish is a sea catfish of the family Ariidae from the eastern Pacific, from Mexico to Panama. The species grows to about 60 cm and has a robust, silvery-grey body with a flattened head, barbels around the mouth, an adipose fin and stout fin spines. It occurs in coastal waters over sandy bottoms and enters estuaries. As a bottom predator it feeds on small 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.
