本文描述了在日本南部Suruga湾海底1-8 m范围内采集到的足头类鱼类，Leptoderma luum [26.9-69.0 mm标准长度（SL）]和Leptoderma retropinnum（21.1-67.2 mm SL）的幼鱼和幼鱼。它们可以很容易地通过以下类似成人的特征来区分：垂直鳍和前尾鳍之间的膜形态（在l . luumvs中分开）。连续inL。背鳍（34-40 vs. 45-52）和侧鳍（50-57 vs. 65-72），尾鳍长度（11.7-13.4% SL vs. 4.5-5.9% SL），以及其他几种身体比例差异。细足头虫幼虫阶段的独特特征包括半透明的枕部，水平细长的眼睛，眼眶上缘以下的头部和被黑细胞密集覆盖的腹腔，个体发育的特征是在屈曲期后获得一般的成年特征，不明显的转变，以及保留少量的幼虫特征直到幼年期结束，与其他已知的足头虫一样。除了这两种物种的近底栖幼虫和幼虫集合外，它们肠道内容物中底栖生物或近底栖分类群（包括Harpacticoida）的出现证实了前者对近底栖生物的早期生活史依赖。
Larvae and juveniles of the alepocephalid fishes,Leptoderma lubricum[26.9–69.0 mm in standard length (SL)] andLeptoderma retropinnum(21.1–67.2 mm SL), collected within 1–8 m of the seafloor in Suruga Bay, southern Japan, are described. They can be easily distinguished from each other by the following adult-like characters: membrane morphology between the vertical fin rays and procurrent caudal-fin rays (separated inL.lubricumvs. continuous inL.retropinnum), numbers of dorsal-fin rays (34–40 vs. 45–52) and anal-fin rays (50–57 vs. 65–72), and caudal peduncle length (11.7–13.4% SL vs. 4.5–5.9% SL), in addition to several other body proportional differences. Unique characters in the larval stages ofLeptodermainclude a translucent occipital region, horizontally elongated eye, and head below the upper margin of the orbit and abdominal cavity densely covered by melanophores, ontogeny being characterized by the acquisition of general adult characters to the postflexion stage, indistinct transformation, and the retention of few larval characters until almost the end of the juvenile stage, as in other known alepocephalids. In addition to the near-bottom larval and juvenile collections of both species, the occurrences of benthic or near-bottom taxa, including Harpacticoida, in their gut contents confirmed the early life history dependence of the former on the near-bottom.
