简单描述 型态特徵 | 形态测量图

背棘 (总数): 0; 臀棘 0; 臀鳍软条: 13 - 15. Most specimens without pre-pelvic scutes, but some with 1 to 5 thin needle-like scutes. Maxilla tip blunt, reaching to front border of pre-operculum, but scarcely projecting beyond second supra-maxilla. Isthmus short, preceded by a small fleshy plate on urohyal between branchial membranes. Anal fin short, its origin behind base of last dorsal fin ray.
没有前腹鳍鳞甲的大多数的标本, 但是一些具有 1 到 5个细的针状鳞甲。 颚骨顶端钝的, 延伸到前鳃盖的前缘, 但是几乎不突出超过第二个上颚骨。 峡部短, 在鳃盖膜之间的尾舌骨上前面有一个小的肉质碟了。 臀鳍短, 它的起点在最后背鳍鳍条的基底后面。

生物学特性     字汇 (例如 epibenthic)

Epipelagic (Ref. 58302). A schooling species living close inshore and entering bays, inlets, estuaries, canals and even penetrating into fish ponds, thus able to tolerate a wide range of salinities. Feeds mainly on planktonic crustacean larvae. Breeds throughout the year, with a peak in summer, spawning at night (between 2200 and 0200 hours) in bays and estuaries (Ref. 189).

一个群游性鱼种生活近岸与湾内,小水湾,河口, 管甚至进入鱼池塘之内, 如此能容忍宽范围的盐度。 主要吃浮游性甲壳类幼生。 全年繁殖, 在被在海湾与河口中产卵在晚上 (在 2200 与 0200 小时之间) 的夏天具有一个高峰。
