生态学
; 淡水; 半咸淡水 大洋性. 熱帶; 10°N - 20°S, 68°W - 34°W (Ref. 188)
South America: lower reaches of the Orinoco; Surinam; Pernambuco and Bahia, Brazil. Many records of the species are unconfirmed and its real distribution is not certain.
南美洲: 奧里諾科河的下游; 蘇利南; 貝南博古與 Bahia 巴西。 此魚種的許多記錄未被證實,而且它的真正分布是不確定的。

成熟度: Lm ?  range ? - ? cm
Max length : 8.0 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; 脊椎骨: 43. Distinguished from the very similar R. amazonica mainly by having more vertebrae and more scales in lateral series. 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. A silver stripe along the flank reported by some authors. Two distinct parallel striae on scales.
Body shape (shape guide): fusiform / normal; Cross section: compressed.
主要地与非常相似的 R. amazonica 区分在侧线列中藉着具有更多的脊椎骨与更多的鳞片。 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。 一条银色的斑纹沿着被一些作者被报告的侧面。 二在鳞片上明显的平行陷纹。
A riverine freshwater species, but also tolerating brackish water.
一个河的淡水种, 也容忍半淡咸水。
