簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 2; 臀棘: 0. This species is distinguished by the following characters: snout long. Slender, and sharply pointed, its length 43-48% HL, 0.5-0.7 into orbit diameter; normally no scales on ventral aspects of head except along anterolateral margin of snout; naked areas dorsally behind anterolateral margins of snout confined to narrow strips; anterolateral edges of snout not supported by bone (median and lateral processes of nasal bone not united); ventral light organ very small, short, situated just before anus; scales large, fairly deciduous, spinules short, imbricate, aligned in 8 to 10, slightly divergent rows; overall color is gray-brown, with a bluish band around trunk; the underside of the head dusky to densely punctuated; the orbit rim black; the fins blackish to dusky (Ref. 1371, 36027).
這種被藉著下列的特徵區別: 吻長的。 細長的, 與非常尖的, 它的長度 43-48% HL, 0.5-0.7 進入眼窩直徑之內; 通常沒有鱗片在頭部的腹面上除了沿著吻的前外側邊緣之外; 裸露區背面在吻的前外側邊緣後面侷限於狹窄的長條; 不被由硬骨 (中動脈與不被結合的鼻骨側面突起) 支撐的吻的前外側邊緣; 腹面發光器非常小的﹐短的, 位於正好在肛門前; 鱗片大的, 非常易脫落的, 小刺短,邊緣重疊成瓦狀, 排列成 8 到 10, 些微分歧的列; 整體的色彩是灰褐色, 軀幹的周圍具有一個藍色的條紋; 頭部的下面暗色的到濃密地加標點符號; 眼窩鑲邊黑色; 鰭黑色的到暗色的.(參考文獻 1371,36027)
Feeds on deep-sea decapod crustaceans, gastropods, and polychaetes (Ref. 1371). Probably taken occasionally in by-catch of commercially important fishes (Ref. 1371).
吃深海的十足目的甲殼動物，腹足動物與多毛類動物。 (參考文獻 1371) 可能在商業重要魚的誤捕偶而捕獲了。 (參考文獻 1371)
