Lesser amberjacks have a proportionately larger eye and deeper body than the greater amberjack. They are olive green or brownish-black with silver sides and usually have a dark band extending upward from their eyes. Juveniles have split or wavy bars on their sides. The average adult-sized fish are usually in the 10 pound range and they are found deeper than other jacks. Juveniles are found shallower near floating objects. Lesser amberjacks feed on squid, smaller fish, and crustaceans.
