简单描述
检索表 | 型态特徵 | 形态测量图
背棘 (总数) : 2. Fully-scaled underside of head and lower jaw; snout long, length 44.5-51.4% HL, dorsal anterior surface upturned in lateral profile; area anterior to and below nostrils covered with scales between nostrils and suborbital ridge; light organ lacking obvious ventral dermal window; anterior of the anal fin dusky, pale posteriorly (Ref. 26363). Similar to a number of moderate- to long-snouted Caelorinchus species which lack distinguishing body or fin markings but may be differentiated from each other based on their body proportions, among other characters (Ref. 26363).
Body shape (shape guide): elongated.
完全覆盖着鳞片头部与下颌的下面; 吻长的, 长度 44.5-51.4% HL, 背部的前面表面的朝上在侧面的轮廓中; 区域位于覆盖着在鼻孔与眶下骨脊之间的鳞片以下鼻孔前; 发光器缺乏明显的腹皮窗; 前面的臀鳍暗色的, 灰白的在后部地.(参考文献 26363) 类似一些中等的- 到长的-鼻口部缺乏有区别的身体或者鳍斑纹的 Caelorinchus 种但是可能从以他们的身体比例为依据的彼此被区别, 在其他的特徵之中.(参考文献 26363)
A benthic species found on the continental slope (Ref. 75154).
