Bagre Catfish Identification Guide

Key identification features

• Streamlined, torpedo-shaped marine body built for open water swimming
• Silvery-blue back fading to a pale white belly, typical of an open-water predator
• Tall, sail-like dorsal fin extending into a long trailing filament
• Long barbels, especially an extended maxillary pair reaching well past the head and sometimes past the pectoral fins
• Deeply forked tail fin with elongated lobes
• Moderate size, commonly reaching 1-2 feet in length, with a fairly slender, laterally compressed body
• Smooth, scaleless skin that appears sleek and metallic when fresh from the water

Common look-alikes

• Hardhead catfish: has a shorter, stockier body and a much shorter dorsal fin filament, without the long trailing extension seen in Bagre catfish
• Other marine catfish species: generally lack the combination of an elongated dorsal filament and extra-long maxillary barbels reaching past the pectoral fins

Where you'll see one

Bagre catfish live in coastal marine and brackish waters of the western Atlantic, including the Gulf of Mexico, often schooling over sandy or muddy bottoms near river mouths, estuaries, and open beaches, particularly in warmer months when they move into shallower coastal waters.
