生态学
; 淡水; 半咸淡水 大洋性. 熱帶; 9°N - 7°S
South America: drainage (Orinoco, as far up as the Rio Manacacias in Colombia, rivers of the Guianas, and Amazon at least as far up as Teffe and the Jutahi River - if specimens were identified correctly - and even as far up as the Ucayali, Huallaga and Moroña Rivers of the upper Amazon).
南美洲: 流域 (奧里諾科河, 向上遠達在哥倫比亞，圭亞那的河與亞馬遜河至少的 Rio Manacacias 向上遠達 Teffe 與 Jutahi 河 - 如果標本正確地被鑑定 - 甚至向上遠達亞馬遜河上游的 Ucayali ， Huallaga 與 Morona 河).
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm ?, range 17 - ? cm
Max length : 30.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 5217); common length : 20.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 5217)
背棘 (总数): 0; 臀棘 0; 臀鳍软条: 26 - 30. Snout about 3/4 eye diameter, maxilla moderate, tip pointed, reaching almost to or just beyond front margin of pre-operculum. gill rakers short and stumpy. Dorsal fin origin well behind midpoint of body; anal fin origin below first to fourth branched dorsal fin rays. Silver stripe along flank, twice eye diameter at widest, lost in fishes over 10 to 12 cm SL; curve of black dots on operculum (Ref. 189).
吻大约 3/4 眼直径, 颚骨中等的, 顶端尖的, 几乎到或正好超过前鳃盖的在前面边缘。 鳃耙短与多残株的。 背鳍起点在身体中央正后方; 在第一个到第四个分枝的背鳍鳍条之下的臀鳍起源。 银色的斑纹沿着侧面, 两次眼直径在宽的, 在超过 10 到 12 公分 SL 的鱼中失去; 在鳃盖上的黑色点的弯曲.(参考文献 189)
Occurs far up rivers, but apparently reaches down to river mouths. Carnivorous, feeds on small fishes and probably crustaceans (Ref. 12225). A ripe female of 17.2 cm SL was recorded at Tucupita, Orinoco delta in Venezuela.
生存在河川最上游, 但是显然地向下延伸到河口。 肉食性, 吃小鱼与可能甲壳动物.(参考文献 12225) 17.2 公分 SL 的一只成熟的母鱼在 Tucupita 被记录, 在委内瑞拉的奥里诺科河三角州。
