背棘 (总数) : 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).
吻长而非常尖的。 发光器小的与短。 鳞片大的, 非常易脱落的, 小刺短,边缘重叠成瓦状, 排列成 8 到 10, 些微分歧的列。 整体的色彩是灰褐色, 躯干的周围具有一个蓝色的条纹; 头部的下面暗色的到厚密地加标点符号; 眼窝镶边黑色; 鳍黑色的到暗色的。
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壳动物，腹足动物与多毛类动物。 (参考文献 1371) 可能在商业重要鱼的误捕偶而捕获了。 (参考文献 1371)
