生态学
; 淡水; 半咸淡水 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。

成熟度: Lm ? range ? - ? cm
Max length : 11.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 105080); common length : 5.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 188)
背棘 (总数) : 0; 背的软条 (总数) : 13 - 21; 臀棘: 0; 臀鳍软条: 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.
腹面有明显的龙骨; 二在鳞片上明显的平行陷纹; 一条银色的斑纹在一些标本中沿着侧面。 于大约眼中心的水平容易地在颚骨的上半部上在区域中与所有的其他鲱鱼分开了藉由锐利的逆向棘。 主要地与非常相似的 R. bahiensis 区分在侧线列中藉着具有较少的脊椎骨 (38 或 39) 与较少的鳞片.(参考文献 188) 身体银色的, 头部黄白色.(参考文献 37032)
A riverine freshwater species, but also tolerates brackish water. Presumably schooling. Feeds on zooplankton.
一个河的淡水种, 也容忍半淡咸水。 推测为群游。 吃浮游动物。
