腹面有大約 26個鱗甲。 下頜不是強烈突出; 顎骨的後部頂端遇見顎骨葉片的低凸起而且被它重疊; 齒非常小或細小的。 背鰭在身體中央正後方; 臀鰭長的, 背鰭起點前的它的起源。 一條銀色的條紋沿著側面。
Occurs in coastal waters and off river mouths (e.g. Río Mayo, Gulf of California) thus perhaps tolerating lowered salinities. Feeds on planktonic crustaceans. Spawns over an extended period off Costa Rica.
出現於如此也許容忍低鹽度的沿岸水域與河口外 (例如 Rio 梅奧 , 加州灣)。 吃浮游性甲殼動物。 產卵經過一長段時間外海的哥斯大黎加。
