Carangidae is a family of fish which includes the jacks, pompanos, jack mackerels, runners, and scads. They are marine fishes found in the Atlantic, Indian and Pacific Oceans. Most species are fast-swimming predatory fishes that hunt in the waters above reefs and in the open sea; some dig in the sea floor for invertebrates. The largest fish in the family, the greater amberjack, Seriola dumerili, grows up to 2 m in length; most fish in the family reach a maximum length of 25–100 cm.
