Scombrids are active predators that feed on a wide range of organisms. The diet of a single species may include crabs, shrimps, squids, crustaceans, the larvae of fishes and invertebrates, and fishes several feet long. Some smaller species strain zooplankton through their gill rakers. Tunas feed on a variety of mid-water and surface fishes, with mackerel providing a favorite meal. Tunas’ ability to maintain elevated body temperatures enables them to swiftly pursue prey in the cold waters of deeper depths and higher latitudes. Migratory tunas have the fastest digestion rates and highest metabolic rates of any fish.
Primary Diet: carnivore (Piscivore , Eats non-insect arthropods)
