生態學
海洋; 半鹹淡水 礁區魚類; 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 / 年齡
Maturity: Lm 15.0 range ? - ? cm
Max length : 27.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 54980); common length : 20.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 188); 最大年齡: 8 年 (Ref. 1488)
背棘 (總數) : 0; 背的軟條 (總數) : 13 - 21; 臀棘: 0; 臀鰭軟條: 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).
鱗甲不是突出。 與 A. clupeoides 與 A. leiogaster 區分藉由有一系列的 10個到 20 金色的 (活著時) 或黑色的 (在保存上) 斑點下來側面 (但是有時不見的) 與更多的下鰓耙; 從 Sardinops 種藉由缺少多骨的放射陷紋在它的鰓蓋; 從 沙丁魚 種用它的較少的腹鰭鰭條與下鰓耙。
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.
出現在沿岸水域與潟湖的一個群游性魚種。 在印尼的Panggang 島，它在 28.5-29.8 °C 與 31.6-32.3個 ppt 的鹽度的溫度被記錄。 (參考文獻 823) 主要吃橈腳類的動物，甲殼類幼生與海蟹幼蟲，二枚貝幼生與腹足動物, 以及 Peridinium 與 Ceratium. 在鮪魚業中當作魚餌了。
