在吻部上的水平的藍色線是特殊的。 (參考文獻 37816,48635) 前額輪廓一般陡峭。 大的成魚在眼的前端上的後頸與一個骨架上發育一個骨脊。 胸鰭葉腋的內面沒有鱗片。 整體的色彩是銀色的有細的褐色鱗片邊緣。 前半部的頭部時常褐色的有一系列的狹窄波動, 在頰部與吻部的側邊上的縱向線。 鰭是黃色或橘色的; 尾鰭時常暗褐色; 橫過胸鰭基底鰭的一條狹窄的褐色橫帶。 在大約 25 公分 SL 下面的稚魚時常 5 或 6條深色的橫帶側邊上與一個深色的橫帶眼睛下面。
Inhabits offshore reefs (Ref. 9710), trawling grounds of the continental shelves and offshore rocky bottoms (Ref. 30573). Juveniles inshore on muddy substrates (Ref. 48635). Solitary or in small groups (Ref. 90102). Feeds mostly on bottom invertebrates and small fishes (Ref. 30573). Potential commercial fish if sufficient stocks can be located (Ref. 9775). Marketed fresh (Ref. 9775); sometimes with a strong and unpleasant flavor (Ref. 11888).
棲息於外海礁石 (參考文獻 9710) ，大陸棚與外海岩石底部的拖網漁場。 (參考文獻 30573) 稚魚在沿海地區的泥質底部。 (參考文獻 48635) 大部份捕食底棲無脊椎動物與小魚。 (參考文獻 30573) 可能的商業魚如果充份的分枝能被設置.(參考文獻 9775) 在市場上銷售生鮮地了;(參考文獻 9775) 有時有一種強而不愉快的滋味。 (參考文獻 11888)
