Lower jaw not strongly projecting; hind tip of maxilla meets lower bulge of maxilla blade and is overlapped by it; teeth very small or minute.

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.
