背棘 (总数) : 10; 背的软条 (总数) : 35 - 39; 臀棘: 2; 臀鳍软条: 7. Diagnosis: moderately sized species with an elongate and laterally compressed body; dorsal with 9 (10?) spines in 1st part, second part with 1 spine and 35-39 soft fin rays; second anal spine clearly shorter than first anal fin soft ray, i.e. about half its length, and robust; pectoral fins long, 23.3-27.3% SL; caudal fin S-shaped; mouth inferior almost horizontal; maxilla extending to posterior half of eye; 7-9/1/4-7 (total 13-18) gill rakers on 1st gill arch; lower part of 1st gill arch with 2-6 reduced additional gill rakers, upper part with 0-2 reduced additional ones; gill rakers moderately long and fine, but shorter than the gill filament at angle between lower and upper part of gill arch; preopercular edge feebly denticulated but never with spines; eyes rather small, 4.6-5.4 times in HL, but this character is difficult to use for identification because of allometry (Ref. 81656).
Coloration: generally very dark, but occasionally pale silver often with faint dark brown oblique lines on sides; ventral side of head and belly yellowish; all fins greyish to very dark brown, black (Ref. 81656).
Occurs in coastal waters from the shore to about 70 m over mud bottom, but moves to deeper water. Also found in estuaries and coastal lagoons (Ref. 3593, 81656). Mainly feeds on benthic invertebrates (Ref. 81656).
出现于沿岸水域距离岸边到大约在泥底上的 70 公尺, 但是移动到较深的水域。 也发现于河口与岸边泻湖。 (参考文献 3593)
