生态学
海洋; 淡水; 半咸淡水; 深度上下限 0 - 35 m (Ref. 86940). 熱帶; 17°N - 7°S, 17°W - 14°E (Ref. 54448)
Africa: Atlantic coasts from northern parts of Senegal south to Baie de Saint-Bras in Angola (Ref. 188, 3509), also in lagoons and river estuaries (Ref. 188, 81270).
東大西洋: 塞內加爾北部南至 Baie de 聖徒-胸罩，安哥拉。
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 13.0, range 13 - 18 cm
Max length : 30.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 27000); common length : 16.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 188); 最大体重: 144.00 g (Ref. 86940)
背棘 (总数) : 0; 背的软条 (总数) : 14 - 17; 臀棘: 0; 臀鳍软条: 45 - 50; 脊椎骨: 42 - 43. Diagnosis: Body moderately deep, compressed, belly with a sharp and serrated keel of scutes from gill opening to anus, 25-27 pre-pelvic and 6-8 post-pelvic sharp scutes (Ref. 187, 188, 81270). Eye large, mouth pointing upwards, lower jaw projecting (Ref. 187, 188). Dorsal fin at or before midpoint of body; anal fin long, with more than 40 finrays, its origin below dorsal fin base; pelvic fins small (Ref. 187, 188). Swimbladder with two short tubes passing back in the muscles on either side of haemal spines (Ref. 188). Other clupeoid fishes in the area are more slender, have a much shorter anal fin and the lower jaw is not strongly projecting (Ref. 188).
腹面有 25 到 27个 +7 或 8个锐利的鳞甲。 眼大的, 下颌突出的。 背鳍在或在身体中央之前; 腹鳍小的; 臀鳍长的, 在背鳍基底之下的它的起源。 在其中任何一个脉棘上的肌肉中泳鳔有二个短的管通过背面。 在区域的其他的鲱鱼是更细长的, 有很多的较短的臀鳍与不突出的下面的颌。
Found in the marine environment, pelagic, along beaches and just off shore, down to about 25 m, also in lagoons and estuaries, penetrating into almost freshwater (Ref. 187, 188, 54448). A marine migrant (Ref. 117399). Rarely found below 35 m depth (Ref. 86940). It feeds on small planktonic animals, e.g. small fish and crustaceans; it doesn't seem to feed on plankton (Ref. 188, 3166, 47405).
发现沿着海滩与快到外海的水域了; 也在泻湖与河口, 进入几乎淡水之内。 吃浮游生物，底栖性无脊椎动物，鱼，与碎屑。 (参考文献 28587)
