fornì da Fishbase
Adults are neritic, confined primarily to temperate waters, but juveniles may be encountered in waters of up to 30°C. Form small schools at the surface so that the first dorsal fin stands out of the water like that of sharks, also frequently associated with birds. Feed on small fishes, especially sardines, anchovies, jacks, mackerel, bogue and others. Eggs and larvae are pelagic (Ref. 6769). Marketed canned or frozen.
