Body silvery with 6-8 irregular, faint dusky oblique and vertical bands dorsolaterally and ventrolaterally (usually more apparent in young stressed or preserved specimens. U-shaped premaxilla groove mostly without scales (tiny scales anteriorly in specimens over 13 cm SL). Posterior margin of maxillary beyond a vertical through anterior margin of pupil. Supraneural bones 3. Spinous dorsal fin with an indistinct dusky patch (2nd-6th spines) and very narrow dusky distal margins on upper membranes between spines. Scales between 5th dorsal fin spine and lateral line 3-4, usually 3.5.

缺乏特殊的特徵而且是更细长的被相较于的其他相似的种。 (参考文献 48635) U 形的前颌骨凹槽大部份没有鳞片。 (极小的鳞片前面在超过 13 公分 SL 的标本中) 颚的后缘超过一垂直的经过瞳孔的前缘。 背外侧地而且腹侧地银色的身体有 6-8 不规则的, 模糊的暗色斜角与垂直的条纹 (通常更明显的在受惊或保存的幼鱼标本中。 在第 5根背鳍棘与侧线 3-4 之间的鳞片, 通常 3.5. 腹鳍新鲜时是半透明或者暗黄色颜色在后部地有一个不明显的暗色条纹与暗白色末梢部的边缘。 在棘之间的上面薄膜上的刺状的背鳍有一个不明显的暗色小区块 (第二-第 6根棘) 与非常狭窄的暗色末梢部的边缘。 上背侧的硬骨 3.(参考文献 35850) G. oyena 能在背鳍 (参考文献 37816) 上被用它的较大鳞片与深色的末端与 G. longirostris(同种异名 G. acinaces) 区分。
Found along the coast, saltwater lagoons, and estuaries (Ref. 5213). Also in sand bottoms in sheltered waters near reefs (Ref. 90102). Occurs singly or in groups (Ref. 9710). Feeds on small organisms living on sandy bottoms. Utilized as fish meal and duck food. Sold fresh in markets.
发现沿着海岸，盐水的泻湖与河口了。 (参考文献 5213) 各别地生存或成群.(参考文献 9710) 吃被生活在砂质底部上的小生物。 用来作鱼粉与鸭子的食物了。 生鲜贩卖在市场中了。
