大小 / 重量 / 年齡
成熟度: Lm ?  range ? - ? cm
Max length : 14.5 cm TL 雄魚/尚未辨別雌雄; (Ref. 96339)
背棘 (總數) : 0; 臀棘: 0; 臀鰭軟條: 23 - 32. Snout moderately pointed, about 3/4 eye diameter; maxilla long, tip sharply pointed, reaching to or just beyond gill opening, but shorter and more blunt at 4 to 5 cm standard length; gill cover canals of walkeri-type. Pectoral fins large, tip reaching to beyond pelvic fin base; anal fin origin below dorsal fin origin or a little behind. Silver stripe along flank, as eye in some places.
Body shape (shape guide): elongated; Cross section: oval.
吻一般尖, 大約 3/4 眼直徑; 顎骨長的, 頂端非常尖的, 延伸到或正好超過鰓裂, 但是更短與更更鈍在 4 到 5 公分標準長度; walkeri 的鰓蓋運河-類型。 胸鰭大的, 頂端延伸到超過腹鰭基底; 在背鰭起點之下的臀鰭起源或稍微往後。 銀色的斑紋沿著側面, 如眼在一些地方中。
Presumably schooling and most often found in warm, murky waters near shore and in bays near river mouths (specimens taken some km up the Rio Santiago, Nayarit, Mexico). Capable of tolerating lower salinities than that of the sea (Ref. 9298). The ovarian eggs are elliptical. Caught as a by-catch of encircling, lamparo, and trawl nets (Ref. 9298).
推測為群游而且最時常發現於溫暖的, 混濁的水近岸與在河口 (佔據一些公里上游 Rio 聖地牙哥, Nayarit ,墨西哥的標本) 附近的海灣中. 能夠超過海洋的容忍低的鹽度。 (參考文獻 9298) 卵巢的卵是橢圓的。 捕捉作為一個圍網,燈光誘捕與拖網的誤捕.(參考文獻 9298)
