生态学
海洋; 半咸淡水 礁区鱼类; 深度上下限 0 - 5 m (Ref. 90102). 熱帶; 23°C - 28°C (Ref. 13614); 35°N - 20°S
Western Pacific: Andaman Islands to Vanuatu, north to Japan, south to New Caledonia. Occurs in the Mekong delta, but possibly may be found as far upstream as the tidal zone (Ref. 12693).
西太平洋: 安達曼群島到萬那度,北至日本, 南至新加勒多尼亞。 出現於湄公河三角州, 但是可能被發現於往上游遠達潮間帶.(參考文獻 12693)
大小 / 重量 / 年龄
成熟度: Lm ? range ? - ? cm
Max length : 16.2 cm TL 雄鱼/尚未辨别雌雄; (Ref. 11344)
背棘 (总数) : 7; 背的软条 (总数) : 10 - 11; 臀棘: 1; 臀鳍软条: 9 - 10; 脊椎骨: 26. Ground color brown, darker dorsally; dusky spots proximally on pectoral fin; blackish pelvic fins. 10 or more predorsal scales. Cheeks and opercula fully scaled. Spines of 1st dorsal fin elongated into filaments. Differs from E. belissimus by having fewer predorsal scales and slightly different details of coloration (Ref. 1602); characterized further by having pectoral rays 16-18; rounded caudal fin; longitudinal scale series 30-33; ctenoid scales except cycloid on nape and isthmus; depth of body 3.6-4.0 in SL (Ref. 90102).
Body shape (shape guide): fusiform / normal; Cross section: oval.
底色褐色, 比较黑的背面; 暗色的斑点近端地在胸鳍上; 黑色的腹鳍。 10个或更多前背的鳞片。 颊与鳃盖完全覆盖着鳞片。 第一背鳍的棘延长变成丝状突起了。 有别于 E. belissimus 藉着具有比较少的前背鳞片与些微不同的细部体色.(参考文献 1602)
Solitary or in groups (Ref. 90102). Inhabits muddy bottoms of shallow, turbid marine to brackish coastal inlets and estuaries. Also lives in shallow coastal waters, large tidal pools, mangroves, siltty lagoons and brackish lakes (Ref. 48637).
栖息于浅滩的泥底部，混浊的海洋到半咸淡的海岸小水湾与河口。 也生活在沿岸浅水区，大的潮池，红树林， siltty 舄湖与半咸淡水湖中。 (参考文献 48637)
