Épines dorsales (Total): 17 - 19; Rayons mous dorsaux (Total): 17-20; Rayons mous anaux: 17 - 20; Vertèbres: 51 - 53. Interpelvic process small and bifid. Lateral line gradually curving down toward caudal peduncle. Vertebrae 21-22 precaudal plus 30-31 caudal, total 51-53. Intestine with 2 folds and 3 limbs. Swim bladder absent. Body covered with small scales. First dorsal fin black anteriorly and at distal margin posteriorly.

Migrates in large schools over great distances along the shore. Larvae are found in surface waters between 19.6° and 29.8°C with salinities of 28.3 to 37.4 ppt. Feeds mainly on small fishes (clupeoids and anchovies), few quantities of penaeoid shrimps and cephalopods. Casting, live-bait fishing, jigging, and drift fishing are also employed in capturing this species. Aerial spotting is sometimes used in locating the fish. Marketed fresh, frozen or smoked; eaten pan-fried, broiled and baked.
