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.

6 胸的絲狀突起; 在最上不達到胸鰭的後頂端。 胸鰭, 鰭條中等又 19-25% 的 SL; 所有的鰭條除了最上面的 1 或 2 以外分枝了。 第二背鰭棘短,5-8% 的 SL。 萎縮了泳鰾，像一個線。 一個大的黑色斑點前面地在側線上.(參考文獻 40958,41110) 沒有上嘴唇; 下唇發展良好的除了在瘉合處之外。 鰓蓋寬廣地圓的; 前鰓蓋骨粗糙地鋸齒狀的。 色彩是金-橄欖色上方 ,下面銀色的。 一個大的橢圓形的斑塊是在那側線的初始.(參考文獻 561)
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).
一個海洋的種發現於大陸棚的泥底部了。 (參考文獻 4340,11230) 時常進入河口而且被發現在沙子或沙泥上面平坦的在 19 到 73 公尺深中.(參考文獻 9685,11230) 主要吃小型甲殼動物 (尤其蝦) ，魚與底棲的生物; 也吃海綿與魚鱗.(參考文獻 9685) 在這一個雌雄同體的發展是雄性先熟的, 由一個稚魚改變成一個雌雄同體, 然後一條母魚.(參考文獻 9685)
