Các tia vây lưng cứng (tổng cộng) : 11 - 13; Các vây lưng mềm (tổng cộng) : 10 - 14; Tia cứng vây hậu môn: 0; Tia mềm vây hậu môn: 10 - 14. Mouth relatively small, upper jaw reaching about to middle of eye. Pectoral fins stout. Interpelvic process short and single. No prominent anterior corselet present. Swim bladder present. Vertebrae 14 precaudal plus 17 caudal, total 31 as in mackerel (Scomber and Rastrelliger).
Inhabits open water but often seen swimming near outer reef walls or deep clear-water slopes (Ref. 48637). Found mostly in shallow reef waters where it forms large schools. Feeds on crustaceans and fishes, particularly clupeoids (Sardinella, Thrissocles), and other fishes such as Sphyraena and Balistes. Marketed canned and frozen (Ref. 9684). Its flesh is mild and pleasantly flavored, but brushed with lemon juice prior to cooking to remove the ammonia-like smell (Ref. 9684).
