; 淡水; 半咸淡水 大洋性. 熱帶; 1°N - 2°S
South America: Amazon drainage (from perhaps mouth of Rio Branco at Goiaçu, Rio Solimões, Rio Juruá and as far as the Río Ucayali in Peru). (There are possibly two species, judging from specimens in the Museu de Zoológia, Sao Paulo).
南美洲: 亞馬遜河流域.(從也許口 Rio Branco 在 Goiacu ， Rio Solimoes, Rio Jurua 與遠達在祕魯的 Rio Ucayali) (可能地有二個種,在 Museu de Zoologia 中由標本看來, 聖保羅).

Maturity: Lm ? range ? - ? cm
Max length : 14.5 cm SL 雄鱼/尚未辨别雌雄; (Ref. 50591); common length : 8.5 cm SL 雄鱼/尚未辨别雌雄; (Ref. 188)
背棘 (总数) : 0; 臀棘: 0; 臀鳍软条: 45 - 54. Belly profile strongly convex (almost circular from throat to anus), 30 to 33 scutes. Lower jaw projecting, mouth directed almost vertically upward; no toothed hypo-maxillary bone between hind end of pre-maxilla and lower bulge of maxilla blade; eye large. Pectoral fins high on body; anal fin origin behind dorsal fin base; upper caudal fin lobe ending in a filament in larger fishes (Ref. 188).
腹面轮廓强烈中凸的 (几乎圆形从咽喉到肛门),30 到 33个鳞甲。 下颌突出的, 嘴直接的几乎垂直向上; 没有在前颚骨与颚骨叶片的低凸起的后部末端之间的有齿皮下注射-上颌骨的硬骨; 眼大的。 胸鳍高高地在身体上; 臀鳍起点在背鳍基底后面; 在较大的鱼中末端形成一个丝状突起的上尾部的鳍叶.(参考文献 188)
Occurs in rivers but perhaps entering slightly saline waters near the mouth of Amazon (but this part of its range is not well documented). Compared with the `flying' characoid fishes (e.g. Thoracocharax), the vertically aligned scute arms in Pristigaster and the rather small pectoral muscles show that flight by vibration of the pectoral fins is almost certainly impossible. This species having been caught along with Thoracocharax raises the question of mimicry.
出现于河但是可能进入亚马逊河的些微盐水域河口附近。 (但是它的分布范围的这一个部份很好地不被证明) 与那相较飞的' 脂鲤科的鱼 (例如 Thoracocharax), Pristigaster 与胸鳍的震动的相当小胸肌显示那飞行的垂直地排列的鳞甲手臂几乎确定不可能。 曾经与 Thoracocharax 一起捕获的这种唤起拟态的问题。
