生态学
海洋; 半咸淡水 礁区鱼类; 深度上下限 10 - 75 m (Ref. 12260). 熱帶; 35°N - 28°S, 31°E - 178°W (Ref. 188)
Indo-West Pacific: Red Sea and Mozambique to the Philippines, north to Taiwan and Okinawa (Japan), south to New Guinea, the Arafura Sea (Ref. 9819), northern Australia, and Fiji.

Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 15.0 range ? - ? cm
Max length : 27.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 54980); common length : 20.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 188); 最大年龄: 8 年 (Ref. 1488)
背棘 (总数): 0; 背的软条 (总数): 13-21; 臀棘 0; 臀鳍软条: 12 - 23. Diagnosis: Body slender, belly rather rounded, scutes not prominent (Ref. 188). It is distinguished from Amblygaster clupeoides and A. leiogaster by the presence of a series of 10-20 gold, in life, or black, on preservation, spots down the flank, but sometimes missing; also, lower gillrakers 33-43, while 26-33 in the other two species (Ref. 188). Sardinops species are also round-bodied and have spots on the flanks, but possess bony radiating striae on the gill cover; round-bodied Sardinella species have one unbranched and 8 branched pelvic finrays while Amblygaster sirm has one unbranched and 7 branched pelvic finrays, and more than 100 gillrakers are present in Sardinella species, also no spots (Ref. 188). Last 2 anal-fin rays enlarged (Ref. 117228).
鳞甲不是突出。 与 A. clupeoides 与 A. leiogaster 区分藉由有一系列的 10个到 20 金色的 (活着时) 或黑色的 (在保存上) 斑点下来侧面 (但是有时不见的) 与更多的下鳃耙; 从 Sardinops 种藉由缺少多骨的放射陷纹在它的鳃盖; 从 沙丁鱼 种用它的较少的腹鳍鳍条与下鳃耙。
A pelagic, schooling species occurring in coastal waters and lagoons (Ref. 188, 53568), at depths of 1-75m (Ref. 82332). In Panggang Island, Indonesia it was recorded in temperatures of 28.5-29.8°C and salinities of 31.6-32.3 ppt (Ref. 823). It feeds mainly on copepods, nauplii and zoea larvae, larval bivalves and gastropods, as well as Peridinium and Ceratium; juveniles also on phytoplankton (Ref. 188). Used as bait in the tuna fishery.
出现在沿岸水域与泻湖的一个群游性鱼种。 在印度尼西亚的Panggang 岛，它在 28.5-29.8 °C 与 31.6-32.3个 ppt 的盐度的温度被记录。 (参考文献 823) 主要吃桡脚类的动物，甲壳类幼生与海蟹幼虫，二枚贝幼生与腹足动物, 以及 Peridinium 与 Ceratium. 在鲔鱼业中当作鱼饵了。
