背的软条 (总数) : 17 - 21; 臀鳍软条: 14 - 18. Body shallow, maximum depth reaching 20%SL. Caudal peduncle relatively long (usually >18%SL). Vertical fin bases against each other. Head not very deep, moderately wide (postorbital width 11-12.5%SL). Snout very short but not blunt; its length 1.5-2.3 times smaller than orbit diameter; olfactory bulbs relatively large; ethymoid in olfactory bulb region relatively narrow. Eyes very large; orbit > 30% HL; no aggregations of light connective tissue in the orbit area around the eyeball; interorbital gap very narrow and < half the orbit diameter. Lacrimal not deep, significantly smaller than lens diameter, slightly overlapping maxillare. Seismosensory canals on head not extended, their pores not enlarged. No separate suprapreoperculum at the upper end of the praeoperculum; preopercular canal connects to the postorbital canal by means of a skin tube. Upper edge of upper jaw overlaps with the vertical of the rear edge of the lens, it may reach the vertical of the back edge of the orbit in large specimens. Supramaxilla 2; front one relatively long; its length equal or shorter than upper outgrowth of the posterior one. Photophores present on the head: a row of 4-5 infraorbitalias; 1 behind back edge of the orbit at its middle level; 5 on both sides along the lower jaw seismosensory canals; 2-4 along the upper 3 rays of the gill membrane; 1 each on the operculum, interoperculum, and between orbit and olfactory capsule. Photophores on body, situated above and below the lateral line, the size increases in the vertical direction that the largest ones cover the lower profile of the body; in front of the vertical fins; 3 rows in the caudal region; several irregular rows of small ones on the gill membranes. Pyloric caeca < 10 (Ref. 36330).
身体水浅又最大的深度达到 20% SL。 尾柄相当长的.(通常 >18% SL) 倚靠彼此的垂直鳍基底。 头部不是非常深, 宽度中等的 (眼眶后的宽度 11-12.5% SL). 吻非常短的但是不是钝; 它的长度 1.5-2.3 倍于眼窝直径; 嗅球相当大的; 在嗅球区域中的筛骨相当狭窄的。 眼非常大的; 眼窝 >30% HL; 在眼窝的淡连接着组织的没有群集环绕着眼球的区域; 眼间骨间隙非常狭窄的与 < 一半的眼窝直径。 泪骨不是深, 重要地比晶状体直径更小, 些微部分重叠的上颌骨。 在不被延伸的头部上的感觉管, 他们的孔不增大了。 在前鳃盖的上端的没有个别的前上鳃盖; 前鳃盖骨管经由皮肤管连接到眶后管。 上颌的上缘与晶状体的后缘的垂直者部分重叠, 它可能在大的个体中联络眼窝的背部边缘的垂直者。 上颌骨 2; 在前面的一相当长的; 它的长度等于或后面那个的短于上面自然的发展。 发光器位于头部之上: 一列 4-5 眶下骨; 在它的中央水平的眼窝的 1个在后背面边缘; 5 在两边上沿着下颌感觉管; 2-4 沿着鳃薄膜的上面 3个鳍条; 1 每个在鳃盖，间鳃盖骨上, 与在眼窝与鼻囊之间。 在身体上的发光器, 位于以下上面了侧线, 大小最大的一些覆盖身体的下面轮廓的垂直方向的增加; 在垂直的鳍之前; 在尾鳍区域中的 3 列; 在鳃膜上的一些不规则的较小列。 幽门盲囊 <10.(参考文献 36330)
