簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 2. Snout moderately pointed, 1.4-1.6 times orbit diameter; anterolateral margin incompletely supported by bone; upper jaw slightly less than 1/3 HL; orbit 1.5-1.8 into postorbital length; subopercle produced into slender point ventrally, the tip protruding slightly beyond angle of preopercle. Color overall dark chocolate brown. Nasal fossa with small scales on anteroventral corner but otherwise naked. Spinules on body scales below dorsal interspace imbricate, broadly trihedral, with wide lateral buttresses, in 3-5 saw-toothed, divergent rows. Anus immediately anterior to anal fin; no external sign of light organ.
Body shape (shape guide): elongated.
吻一般尖,1.4-1.6 倍眼窩直徑; 前外側的邊緣不完全地由硬骨支撐了; 上頜些微地少於 1/3 HL; 進入眼眶後的長度之內的眼窩 1.5-1.8; 子鰓蓋腹地伸展到細長的點了,頂端伸出前鰓蓋骨的略超過角。 顏色全體深褐色。 在前腹的角落上鼻窩有小鱗片但是不一樣地裸露的。 在背部的間隙之下的在身體鱗片上的小刺重疊成瓦狀的﹐寬廣有三面, 有寬的側面拱壁, 在 3-5 鋸齒狀又分歧的列中。 肛門緊鄰臀鰭之前; 發光器的沒有外部符號。
