背棘 (總數): 7; 背的軟條 (總數): 112; 臀棘 1; 臀鰭軟條: 9 - 10. Diagnosis: mental barbels long, nasal barbels shorter; 4-5 rows of teeth in upper jaw, teeth in outer row larger than teeth in inner rows, which are curved posteriorly; 4 rows of slightly recurved teeth in lower jaw, outer row with largest teeth, except for mid-lateral teeth of inner row, which are similar in size to teeth in outer row; operculum, suboperculum and suborbital region scaleless; nape with some (maximum 14) small cycloid predorsal scales in a narrow band, not extending anteriorly beyond level of preoperculum; scales on abdomen smaller than those on flanks; 30-34 (usually 33 or 34) ctenoid scales in a longitudinal series (including 2 scales on caudal fin base), and 10-12 (usually 11) in rearward transverse series; 1st dorsal fin: VI; 2nd dorsal fin: I,11-12; anal fin: I,9-10; pectoral fins: 18-19 (rarely 17); caudal fin with 16-17 segmented rays, 14-15 of which are branched (Ref. 57403, 79590).
Coloration: Preserved specimens: light brown, with dark spots on flanks forming up to 10 irregular, dark cross bars, darkest at lateral midline; dorsal-fin rays with 3-4 spots, forming irregular longitudinal bands on fins; pectorals with a dark spot at upper part of base, distinct in life but fading after lengthy or poor preservation; caudal fin with spots forming vertical bands (Ref. 57403, 79590). In life: bands and spots on fins more distinct; body yellowish ventrally, yellowish brown dorsally; suborbital region with alternating yellow and dark patches (Ref. 57403, 79590).
Common in brackish waters of estuaries, but may migrate up rivers into freshwaters, often at considerable distance from the sea (Ref. 57403, 79590). Maximum reported standard length 65.1 mm (=78 mm TL)(Ref. 79590).
在潮間帶中生活在沿岸地區。
