Pectoral fin a little longer than head; dorsal fin origin nearer to caudal fin base than to vertical from pectoral fin base by 1 and 1/2 eye diameters (or behind midpoint of body by 2 and 1/4 eye diameter); anal fin long, its origin much nearer to snout tip than to caudal fin base.

腹面有大约 29个鳞甲。 下颌突出的, 它的嘴朝向斜上方; 没有皮下注射-颚骨。 胸鳍稍微长度超过头部; 背鳍起点较接近尾鳍基底超过到垂直的从胸鳍基底 1 与 1/2 眼直径;(或身体的中点后面 2 与 1/4 眼直径) 臀鳍长的, 它的起源很多超过到尾鳍基底较接近吻顶端。
Occurs in coastal waters, perhaps entering brackish water (Ref. 9336). Feeds mainly on small fishes (Ref. 9336).
出现于沿岸水域, 也许进入半淡咸水。 (参考文献 9336) 主要吃小鱼。 (参考文献 9336)
