Maturity: Lm ? range ? - ? cm
Max length : 84.0 cm FL 雄魚/尚未辨別雌雄; (Ref. 168); common length : 60.0 cm FL 雄魚/尚未辨別雌雄; (Ref. 9340); 最大體重: 9.1 kg (Ref. 168)
背棘 (總數) : 10 - 15; 臀鰭軟條: 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.
第一背鰭的前面棘比那些中間者高許多, 給鰭一強烈地凹曲輪廓。 腹鰭間的突起小而兩裂的。 身體裸露的除了甲胄與側線。 泳鰾不存在。 在第 31 與第 32個脊椎骨上的一個大的圓形突起。 色彩是通常藍色虹彩的有黑色的背部斑紋組成物為 3 到 5條水平的斑紋。 也有可變的黑色或者在腹鰭上面的深灰色斑點。 偶然地以廣泛縱向斑紋淡灰色的在腹面上; 一些個體有很少或沒有腹面斑紋。
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.
很少地生存在哪裡表面的溫度低於 23個 ° C. 它的仔魚更時常在 26 °C 上面的溫度被見到而且實際地被侷限於水域大約在在大陸外 240 哩處之內。 棲息在沿岸水域與離岸水域的表面附近。 (參考文獻 11035) 以 黃鰭鮪〔Thunnus albacares〕 與 正鰹〔Katsuwonus pelamis〕 形成多魚種的魚群。 和其他的鮪魚與可能分享食物的一個隨機的掠食者與其他的種競爭食物例如黃鰭鮪魚，海豚, 東方的鰹， et。
