Feed on small fishes, particularly anchovies, crustaceans (especially crab and stomatopod larvae) and squids. Eggs and larvae are pelagic (Ref. 6769). Because of their abundance, they are considered an important element of the food web, particularly as forage for other species of commercial interest.
