Max length : 32.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 44894); common length : 15.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 44894); 最大年龄: 11 年 (Ref. 6996)
背棘 (总数) : 0; 背的软条 (总数) : 12 - 18; 臀棘: 0; 臀鳍软条: 16 - 27. Body fairly elongate, belly keeled, with 16 to 18 + 14 or 15 scutes; about 14 dorsal scutes with low keel from head to dorsal fin origin. Minute or no teeth in jaws; second supra-maxilla slender. Branchiostegal rays 8. Anal fin origin far behind dorsal fin base. Juveniles resemble Hyperlophus, which has a deeper second supra-maxilla, only 4 branchiostegal rays and i 6 pelvic fin rays.
身体相当延长, 龙骨的腹面, 藉由 16 到 18个 +14 或 15 鳞甲; 用低的从头部到背鳍起点的龙骨脊的大约 14个背部的鳞甲。 细小或没有颚中的牙齿; 第二个上颚骨细长的。 鳃条骨 8. 臀鳍起源在背鳍基底后方远处。 稚鱼与 Hyperlophus 相似, 有一个比较深的第二上颚骨，只有 4个鳃条骨与 i 6个腹鳍鳍条。
It occurs in clear, moderately fast-flowing streams, as well as in quiet backwaters, estuaries, and in the sea ( Ref. 5259, 44894). Also found in sluggish lowland rivers (Ref. 44894). A schooling species and appears diadromous. A fast swimming, shoal-forming species. Nothing much is known of its biology, although it may have a catadromous life cycle. Downstream migration to estuaries, presumably for spawning, has been reported in winter months (July-August). Feeds on worms, small crustaceans and insects (Ref. 44894). Breeds in estuaries in July to August. Taken in nets during the spawning season; will also take bait.
它出现于清澈又一般快速流动的溪流中, 以及在安静的洄水区，河口中, 与在海洋中.( 参考文献 5259,44894) 也发现于缓动性的低地河。 (参考文献 44894) 一个群游性鱼种而且出现河海洄游性。 快速的游泳, 形成浅滩的种。 没事很多的被知道它的生物学特性, 虽然它可能有一个降海洄游的生命周期。 下游回游到河口, 可能进行产卵, 已经被报告冬天时数个月 (七月-八月). 吃蠕虫，小型甲壳动物与昆虫。 (参考文献 44894) 在七月到八月繁殖于河口。 在产卵季节的时候采自了网; 也吃誘餌。
