簡短描述 型態特徵 | 形態測量圖

背棘 (總數): 14 - 16; 背的軟條 (總數): 14-15; 臀棘 0; 臀鰭軟條: 14 - 15; 脊椎骨: 41. Interpelvic process small and bifid. Body without scales except for the corselet and the lateral line. Swim bladder absent.

生物學特性     字彙 (例如 epibenthic)

Found in offshore waters; larvae restricted to waters with surface temperatures of 15°C to 30°C (Ref. 6390). Exhibit a strong tendency to school in surface waters with birds, drifting objects, sharks, whales and may show a characteristic behavior like jumping, feeding, foaming, etc. Feed on fishes, crustaceans, cephalopods and mollusks; cannibalism is common. Spawn throughout the year in the tropics, eggs released in several portions (Ref. 35388). Eggs and larvae are pelagic (Ref. 6769). Preyed upon by large pelagic fishes (Ref. 6885). Also taken by trolling on light tackle using plugs, spoons, feathers, or strip bait (Ref. 9684). Marketed fresh, frozen or canned (Ref. 9340); also dried-salted and smoked (Ref. 9987).

發現於離岸水域了; 仔魚用對 30 °C 的 15 °C 的表面溫度侷限於水域了。 (參考文獻 6390) 強烈地趨向於在水表群集伴隨著鳥, 漂流目標,鯊魚, 鯨而且可能顯示一個特殊的行為類似跳躍, 進食,起泡沫, 等等捕食魚,甲殼動物,頭足類動物與軟體動物; 嗜食同類是普遍。 被大的大洋性的魚捕食了。 (參考文獻 6885) 在使用人工餌,匙形假餌,條狀誘餌的輕型漁具上也用拖釣捕獲。 (參考文獻 9684) 在市場上銷售生鮮地了, 凍結或裝於罐頭;(參考文獻 9340) 也乾燥鹽醃而且煙燻.(參考文獻 9987) 在熱帶中產卵全年度, 卵分好幾次釋出.(參考文獻 35388)
