Also known as the cobia, this species is found in warm-temperate to tropical waters of the West and East Atlantic Ocean, throughout the Caribbean, and in the Indo-Pacific off India, Australia and Japan. It is eurythermal, tolerating a wider range of temperatures.
This species is normally solitary except for annual spawning aggregations, and sometimes it will congregate at reefs, wrecks, harbours, buoys, and other structural oases. It is pelagic, but it may enter estuaries and mangroves in search of prey.
It feeds primarily on crabs, squid, and fish. It will follow larger animals such as sharks, turtles, and manta rays to scavenge. It is a very curious fish, showing little fear of boats. Its predators are not well documented, but the mahi-mahi is known to feed on juveniles and the shortfin mako shark eats the adults.

At Restaurante Alfonso, situated on stilts over the shallow waters of the lagoon below off the coast of Isla Bastimentos, fish were frequent, especially because guests were wont to either drop or throw crumbs or rice into the water to attract wildlife. Vast schools of tiny fish were interspersed with bright yellow sergeantfish and the elongated needlefish with grasping mouths that looked like iridescent barracudas. When the food hit the water, the larger ones would actually leap out over the surface to get first grab, as one sergeantfish is doing here.
