carangids

Carangids are a family of marine fish belonging to the order Carangiformes. This diverse family, commonly known as jacks, trevallies, or scads, is found in tropical and subtropical oceans worldwide. They are characterized by their streamlined bodies, two dorsal fins, and typically a forked tail fin. Many carangids possess prominent keels on the caudal peduncle, which are thought to aid in maneuverability. Their coloration can vary greatly, from silvery to dark blues and greens, often with iridescent hues.

The diet of carangids is primarily carnivorous, consisting of smaller fish, crustaceans, and cephalopods. They are often active predators, known for their speed and agility. Carangid species exhibit a wide range of sizes, from small scads just a few inches long to large jacks that can exceed three feet in length. This family includes commercially important species, such as the almaco jack and various trevally species, which are popular targets for recreational and commercial fisheries. They are also sometimes kept in large public aquariums due to their active nature and striking appearance.
