Malabar trevally taking species of polychaete worms as the preferred species. Studies on gill filtering mechanisms has shown the Malabar trevally's anatomy lies between two extremes, one which is a high filtration area characteristic of planktivorous species and the other of very low area which is associated with species which take large prey items. This further suggests the Malabar trevally can filter the small krill type prey, as well as taking larger fishes and squid. Seasonal diet fluctuation in the species has been observed in northern Australia, where a seasonal abundance of squid causes the preferred prey to change from paenid shrimp
