Maturity: Lm ? range ? - ? cm
Max length : 84.0 cm FL 雄鱼/尚未辨别雌雄; (Ref. 168); common length : 60.0 cm FL 雄鱼/尚未辨别雌雄; (Ref. 9340); 最大体重: 9.1 kg (Ref. 168)
背棘 (总数) : 10 - 15; 臀鳍软条: 11 - 12; 脊椎骨: 37. Anterior spines of first dorsal fin much higher than those mid-way, giving the fin a strongly concave outline. Interpelvic process small and bifid. Body naked except for corselet and lateral line. Swim bladder absent. A large rounded protuberances on 31st and 32nd vertebrae. Color is generally iridescent blue with black dorsal markings composed of 3 to 5 horizontal stripes. Also with variable black or dark gray spots above the pelvic fins. Occasionally with extensive longitudinal stripes of light gray on belly; some individuals have few or no belly markings.
第一背鳍的前面棘比那些中间者高许多, 给鳍一强烈地凹曲轮廓。 腹鳍间的突起小而两裂的。 身体裸露的除了甲胄与侧线。 泳鳔不存在。 在第 31 与第 32个脊椎骨上的一个大的圆形突起。 色彩是通常蓝色虹彩的有黑色的背部斑纹组成物为 3 到 5条水平的斑纹。 也有可变的黑色或者在腹鳍上面的深灰色斑点。 偶然地以广泛纵向斑纹淡灰色的在腹面上; 一些个体有很少或没有腹面斑纹。
Occurs rarely where surface temperatures fall below 23°C. Its larvae are more frequently encountered at temperatures above 26°C and are practically confined to waters within about 240 miles off the mainland. Inhabits near the surface of coastal waters and offshore waters (Ref. 11035). Form multi-species schools with Thunnus albacares and Katsuwonus pelamis. An opportunistic predator which shares feeding pattern with other tunas and probably compete for food with other species such as yellowfin tuna, common dolphin, oriental bonito, among others.
很少地生存在哪里表面的温度低于 23个 ° C. 它的仔鱼更时常在 26 °C 上面的温度被见到而且实际地被局限于水域大约在在大陆外 240 哩处之内。 栖息在沿岸水域与离岸水域的表面附近。 (参考文献 11035) 以 黄鳍鲔［Thunnus albacares］ 与 正鲣［Katsuwonus pelamis］ 形成多鱼种的鱼群。 和其他的鲔鱼与可能分享食物的一个随机的掠食者与其他的种竞争食物例如黄鳍鲔鱼，海豚, 东方的鲣， et。
