简单描述
型态特徵 | 形态测量图
Diagnosis: small, closely-packed teeth; relatively small maximum size; larger specimens often with bright greenish metallic iridescence on upper surface of the body, mature males can be more bluish-grey (Ref. 55949).
鉴别: 小又紧密的齿; 相当小的最大体长; 比较大的标本时常在身体的上表皮上有亮的呈绿色的金属彩虹色, 成熟的雄性可能是更蓝灰色的。 (参考文献 55949)
描述: 超过大部分的小又流线型的鱼具有较小的嘴与齿同属的; 鳃盖有相当大的表面区域与呈方形的外表; 颊的相当深的; 眼大的; 齿非常小的而且挤在一起; 鳃耙通常长的﹐不分枝的与紧密的.(参考文献 55949)
体色 身体 countershaded, 深灰色的背面; 不成熟的鱼与两性的成熟鱼可能有灰色的-白色或橘黄色的腹鳍; 在那里在臀鳍上可能是 3-6個黃色或略帶桃色的卵斑點; 水族館保持的標本有時顯示模糊的狹窄縱帶。 (參考文獻 55949)
Found in reedy bays and lagoons, at open sandy beaches, throughout the shelf and reef zones (Ref. 55949), and in the open water (Ref. 5595, 55949). Piscivorous (Ref. 5595, 55949). Small specimens mostly feed on crustacean zooplankton, adults predominantly eat larvae and juveniles of small shoaling zooplanktivorous cyprinid Engraulicypris sardella; female mouthbrooder (Ref. 55949).
在大陆棚与礁区 (参考文献 55949) 各处，在开放的沙滩，发现于芦苇丛生的海湾与舄湖了, 与在开放水域中.(参考文献 5595,55949) 以鱼为食的.(参考文献 5595,55949) 小的标本大部份吃甲壳类的浮游动物, 成鱼主要吃小的浅滩嗜食浮游动物的鲤鱼 沙丁鳀波鱼〔Engraulicypris sardella〕 的仔鱼与稚鱼; 雌性的口孵者.(参考文献 55949)
