Body without spots nor stripes. Pectoral fin rays unbranched; 4th pectoral filament long, 40-53% of SL. Second spine of dorsal fin more robust than the rest. Posterior margin of maxilla extending considerably beyond level of posterior margin of adipose eyelid. Lower tip of 7th proximal pterygiophore of 1st dorsal fin directed backward. Lateral squamation on caudal fin unbranched (Ref. 40970).
身體沒有斑點也不斑紋。 胸鰭鰭條不分枝的; 第 4個胸鰭絲狀突起長又 40-53% 的 SL。 背鰭的第二根棘比其他部分更結實。 非常地延伸超過脂眼瞼的後緣的水平的顎骨的後緣。 第一背鰭的第 7 近端支鰭骨的較低的頂端朝向後面。 在尾鰭上的側面的鱗片排列不分枝的.(參考文獻 40970)
Found in shallow, turbid waters coastal waters, estuaries, mangrove creeks, and mangrove-lined rivers (Ref. 57343), over sandbanks and mud substrates (Ref. 6390). Usually forms loose schools, although larger fish are more often observed in pairs or singly (Ref. 6390). Feeds on prawns and fish. Protandrous hermaphrodites.
通常居住於淺灘, 時常在沙洲與泥底部上的混濁水.(參考文獻 6390) 發現於靠近了而且在紅樹林區域中與在低 Purari 河流域的紅樹林與沼澤之間的 Nypa 手掌的周圍沿著新幾內亞的海岸。 他們通常形成鬆散的魚群, 雖然較大的魚更時常被成對或各別地觀察。 (參考文獻 6390) 捕食蝦與魚。 雄性先熟的雌雄同體是。
Life cycle and mating behavior
成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
King threadfin between 70 cm and 100 cm FL may be transitional hermaphrodites (they possess mature male and immature female reproductive tissue, and function as males (Ref. 28736)). However, most king threadfin less than 80 cm FL are males and most more than 95 cm FL are females (Ref. 28737). Transitional king threadfin are most often found in the months of June, July, August and September (Ref. 6390).
There is little information on the larvae, although nursery areas are known to be inshore, shallow and of low salinity (Ref. 6390).印度-西太平洋: 孟加拉灣 (參考文獻 28735) ，澳洲與新幾內亞。
