soft rays: 14 - 16;
Vertebrae: 44 - 45. Mouth moderately large. Laminae of olfactory rosette 21 to 39. Interpelvic process small and bifid. Body completely covered with very small scales posterior to the corselet. Swim bladder absent. Spleen large and prominent in ventral view. Liver with elongate left and right lobes and a short middle lobe. Back with narrow oblique stripes.
A coastal species (Ref. 9340) found schooling with small tunas. Also found around some islands (Ref. 9684). Feeds on clupeoids, other fishes, squids and decapod crustaceans. Spawning varies with the monsoon season (Ref. 9684). Also caught with troll lines, encircling nets (Ref. 9340) and drift nets (Ref. 9684). Marketed mainly fresh; also dried-salted (Ref. 9684), canned and frozen (Ref. 9987).
