生態學
海洋; 淡水; 半鹹淡水; 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 / 年齡
Maturity: Lm 13.0, range 13 - 18 cm
Max length : 30.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 27000); common length : 16.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 188); 最大體重: 144.00 g (Ref. 86940)
背棘 (總數) : 0; 背的軟條 (總數) : 14 - 17; 臀棘: 0; 臀鰭軟條: 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個 +7 或 8個銳利的鱗甲。 眼大的, 下頜突出的。 背鰭在或在身體中央之前; 腹鰭小的; 臀鰭長的, 在背鰭基底之下的它的起源。 在其中任何一個脈棘上的肌肉中泳鰾有二個短的管通過背面。 在區域的其他的鯡魚是更細長的, 有很多的較短的臀鰭與不突出的下面的頜。
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).
發現沿著海灘與快到外海的水域了; 也在潟湖與河口, 進入幾乎淡水之內。 吃浮游生物，底棲性無脊椎動物，魚，與碎屑。 (參考文獻 28587)
