Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 45.0 cm FL male/unsexed; (Ref. 168); common length : 35.0 cm FL male/unsexed; (Ref. 168); max. published weight: 2.0 kg (Ref. 168)
(total): 16 - 18;
soft rays: 15 - 17;
Vertebrae: 45 - 50. Mouth rather large, upper jaw reaching to hind margin of eye. Laminae of olfactory rosette 28 to 33. Interpelvic process small and bifid. Body mostly naked behind the well developed corselet except for a band of scales along the bases of dorsal and anal fins and patches around the bases of the pectoral and pelvic fins. Swim bladder absent. The back is deep blue, covered with elongate black spots; the belly is light with several stripes like those of the skipjack tuna.
