Description

The gafftopsail sea catfish (Bagre marinus) is a sea catfish of the family Ariidae from the western Atlantic. The species has an elongate, greyish body with long, thread-like extensions on the dorsal and pectoral fins and reaches about 69 cm. It is mainly marine but enters brackish estuaries. It is an opportunistic feeder over mud and sandy bottoms, feeding mainly on small fishes and invertebrates. The dorsal and pectoral fins bear a serrated, erectile and venomous spine.
