简单描述 型态特徵 | 形态测量图

背棘 (总数): 9; 背的软条 (总数): 12-13; 臀棘 3; 臀鳍软条: 11 - 13; 脊椎骨: 24. With 6 pectoral filaments; uppermost not reaching posterior tip of pectoral fin. Pectoral fin, rays moderate, 19-25% of SL; all rays branched except uppermost 1 or 2. Second dorsal spine short, 5-8% of SL. Atrophied swim bladder, like a string. A large black spot anteriorly on lateral line (Ref. 40958, 41110). No upper lip; lower lip well-developed except at symphysis. Operculum broadly rounded; preoperculum coarsely serrated. Color is golden-olive above ,silvery below. A large oval blotch is at the start of the lateral line (Ref. 561).
6 胸的丝状突起; 在最上不达到胸鳍的后顶端。 胸鳍, 鳍条中等又 19-25% 的 SL; 所有的鳍条除了最上面的 1 或 2 以外分枝了。 第二背鳍棘短,5-8% 的 SL。 萎缩了泳鳔,像一个线。 一个大的黑色斑点前面地在侧联机.(参考文献 40958,41110) 没有上嘴唇; 下唇发展良好的除了在愈合处之外。 鳃盖宽广地圆的; 前鳃盖骨粗糙地锯齿状的。 色彩是金-橄榄色上方 ,下面银色的。 一个大的椭圆形的斑块是在那侧线的初始.(参考文献 561)

生物学特性     字汇 (例如 epibenthic)

A marine species found on sandy and muddy bottoms of the continental shelf (Ref. 4340, 11230, 57343). Frequently enters estuaries (Ref. 9685, 11230). Feeds mainly on small crustaceans (especially shrimps), fishes and benthic organisms; also on sponges and fish scales (Ref. 9685). The progression in this hermaphrodite is protandrous, changing from a juvenile to a hermaphrodite, then a female (Ref. 9685).

一个海洋的种发现于大陆棚的沙泥底了。 (参考文献 4340,11230,57343) 时常进入河口。 (参考文献 9685,11230) 主要吃小型甲壳动物 (尤其虾) ,鱼与底栖的生物; 也吃海绵与鱼鳞.(参考文献 9685) 在这一个雌雄同体的发展是雄性先熟的, 由一个稚鱼改变成一个雌雄同体, 然后一条母鱼.(参考文献 9685)
