简单描述 型态特徵 | 形态测量图

背棘 (总数): 10; 背的软条 (总数): 13-14; 臀棘 3; 臀鳍软条: 7 - 9. This species is distinguished by the following characters: body moderately deep; greatest depth 2.5-3.0 in SL; preopercular notch and knob poorly developed; vomerine tooth patch triangular, with a medial posterior extension; gill rakers of first gill arch 6-7 + 10-14 - 16-21; caudal fin truncate to slightly emarginate; scale rows on back parallel to lateral line. Colour of back and upper sides dark brown, lower sides and belly whitish with a silver sheen; usually a series of 4-5 narrow yellow stripes on the sides below the lateral line; a distinct round, black spot on the back below the posterior part of the spinous portion of the dorsal fin (Ref. 9821, 90102).


头部的背面轮廓中等倾斜。 眶前骨非常狭窄的, 它的宽度大约一半的眼直径。 前鳃盖骨凹槽与疖瘤发展不良的。 鳞片列背面平行于侧线。 背面与上侧面深褐色的; 下侧与腹面微白色的具有一个银色的光辉。 时常在侧线之下侧边上有一系列的四或五条狭窄的黄色斑纹。 一个突出的圆, 在背鳍的刺状部分的后面的部份之下的在背部上的黑色的斑点。 L. ehrenbergii 有别于 L. fulviflamma 在平行于侧线的上背部上藉着具有鳞片列.(参考文献 37816)

生物学特性     字汇 (例如 epibenthic)

Adults inhabit very shallow coastal habitats, often in large schools near freshwater run-offs (Ref. 48635). Juveniles often intertidal (Ref. 48635); over sand, silt, or coral rubble bottoms, occasionally in mangrove-lined streams and estuaries (Ref. 9821) They may enter freshwater to feed (Ref. 245); on small fish and invertebrates (Ref. 5213). This is a small species commonly utilized in subsistence fisheries and also seen in markets. Caught mainly with handlines, traps, and gill nets and are marketed mostly fresh (Ref. 9821).

栖息于很浅的海岸栖息地, 时常在淡水的溢流附近的大群鱼群中.(参考文献 48635) 稚鱼时常潮间带的.(参考文献 48635) 吃小鱼与无脊椎动物。 (参考文献 5213) 可能进入淡水觅食.(参考文献 245)
