CobiaRachycentridae

Cobia (Rachycentridae) possess an elongated, somewhat fusiform body with a broad, flattened head. These large pelagic fish reach up to 2 meters (6.6 ft) in length and 68 kg (150 lbs). Their dorsal coloration ranges from dark brown to black, fading to white or silvery on the underside, marked by a prominent dark lateral stripe running from the snout to the tail.

Cobia inhabit open waters but frequently associate with submerged or floating structures, including reefs, wrecks, buoys, and debris, from the surface down to approximately 120 meters (400 ft). They are opportunistic predators, feeding on fish, crabs, shrimp, and squid. Cobia are often observed swimming closely alongside larger marine animals such as sharks, rays, and turtles, a behaviour resembling that of a remora. Divers encounter cobia infrequently.
