身體相當延長, 龍骨的腹面, 藉由 16 到 18個 +14 或 15 鱗甲; 用低的從頭部到背鰭起點的龍骨脊的大約 14個背部的鱗甲。 細小或沒有顎中的牙齒; 第二個上顎骨細長的。 鰓條骨 8. 臀鰭起源在背鰭基底後方遠處。 稚魚與 Hyperlophus 相似, 有一個比較深的第二上顎骨，只有 4個鰓條骨與 i 6個腹鰭鰭條。
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.
一個群游性魚種而且出現河海洄游性。 它出現於清澈又一般快速流動的溪流中, 以及在安靜的洄水區，河口中, 與在海洋中.( 參考文獻 5259) 吃蝦，蠕蟲與昆蟲。 在七月到八月繁殖於河口。 在產卵季節的時候採自了網; 也吃誘餌。
