生態學
; 淡水; 半鹹淡水 大洋性. 熱帶; 10°N - 8°S, 69°W - 47°W (Ref. 188)
South America: lower reaches of the Orinoco, rivers of the Guianas, Amazon at Pará, but undoubtedly elsewhere in its lower part.
南美洲: 奧里諾科河的下游，圭亞那，帕拉的亞馬遜河的河, 但是毫無疑問地在它的較下面的部位中的別地方。
大小 / 重量 / 年齡
成熟度: Lm ? range ? - ? cm
Max length : 11.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 105080); common length : 5.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 188)
背棘 (總數) : 0; 背的軟條 (總數) : 13 - 21; 臀棘: 0; 臀鰭軟條: 15 - 18. Belly strongly keeled; two distinct parallel striae on scales; a silver stripe along flank in some specimens. Easily separated from all other clupeids in the area by the sharp retrorse spine on the upper part of the maxilla at about the level of the eye center. Distinguished from the very similar R. bahiensis mainly by having fewer vertebrae (38 or 39) and fewer scales in lateral series (Ref. 188). Body silvery, head yellowish white (Ref. 37032).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
腹面有明顯的龍骨; 二在鱗片上明顯的平行陷紋; 一條銀色的斑紋在一些標本中沿著側面。 於大約眼中心的水平容易地在顎骨的上半部上在區域中與所有的其他鯡魚分開了藉由銳利的逆向棘。 主要地與非常相似的 R. bahiensis 區分在側線列中藉著具有較少的脊椎骨 (38 或 39) 與較少的鱗片.(參考文獻 188) 身體銀色的, 頭部黃白色.(參考文獻 37032)
A riverine freshwater species, but also tolerates brackish water. Presumably schooling. Feeds on zooplankton.
一個河的淡水種, 也容忍半淡鹹水。 推測為群游。 吃浮游動物。
