生態學
; 淡水; 半鹹淡水 大洋性; 河川洄游 (Ref. 51243). 熱帶; 9°N - 4°S, 73°W - 49°W (Ref. 189)
South America: Orinoco system, as far up as Puerto Gaitan on Manacacias River in Colombia, certainly in delta; lower parts of rivers of Guyana, Surinam and French Guiana; lower part of Amazon, but lower limits not known; upper Amazon specimens are not this species.
南美洲: 奧里諾科河流域,在哥倫比亞的 Manacacias 河上向上遠達 Puerto Gaitan, 確定地在三角州中; 蓋亞那，蘇利南與法屬圭亞那的河川下游; 亞馬遜河的下游部分, 但是不為人所知的限制下游; 亞馬遜河上游標本不是這種。

背棘 (總數) : 0; 臀棘: 0; 臀鰭軟條: 14 - 18. Body fairly slender, moderately compressed. Snout short, a little over 1/2 eye diameter; maxilla moderate, tip bluntly rounded, failing to reach pre-operculum by 1/3 to 1/2 pupil diameter; gill cover canals of walkeri-type. Anal fin short, its origin a little behind base of last dorsal fin ray. A silver stripe along flank, widening to about 1/2 eye diameter over anal fin base (Ref. 189).
身體非常細長的, 中等側扁。 吻短, 稍微超過 1/2 眼直徑; 顎骨中等的, 頂端鈍地圓的, 失敗達到 1/3 到 1/2 瞳孔直徑的前鰓蓋; walkeri 的鰓蓋運河-類型。 臀鰭短, 它的起源最後背鰭鰭條的稍微往後基底。 一條銀色的斑紋沿著側面, 對在臀鰭基底上的大約 1/2 眼直徑擴大。 (參考文獻 189)
Occurs in estuaries and rivers, apparently tolerating only very low salinities. Breeds in December: a female of 5.8 cm SL having 2,000 eggs was caught from the Orinoco River mouth (Ref. 12225)..
出現於河口與河,顯然地容忍只有非常低的鹽度。 繁殖於十二月: 有 2,000個卵的 5.8 公分 SL 的一條母魚被捕捉從奧里諾科河河口。 (參考文獻 12225)。
