背面の脊椎 (合計): 0; 背鰭 (合計): 12-18; 肛門の骨 0; 臀鰭: 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.
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.
