Many of the species are large, free-roaming fish that gather around offshore structures and wrecks, and also in open water. Inshore reefs and creeks are home to smaller species such as the orange-spotted jack, Carangoides bajad .Most species in this large family are overall silvery-grey in colour, with distinctive individual markings, including dark blotches, indistinct patches and black or orange spots. Carangidae swim in schools of a hundred or more fish, although larger species tend to be more solitary or hunt in smaller numbers.
