对采自东/日本海的3条全长分别为22.2、22.7、56.0 mm的细头鱼进行了形态和遗传分析，鉴定为蛇鱼科(Anguliformes，Ophichthidae)的Scolecchelys属。形态特征为：肌球148~158个，肠壁肿胀10个，背鳍位于身体中部以上，肛门与尾缘之间有6个后黑素载体。对线粒体DNA的12SRRNA序列分析表明，该序列与成虫一致(遗传距离=0.001)。此外，成虫的肌球总数与椎骨总数一致。本研究首次描述了淡色海鞘的形态特征及其随大小的变化。该种的韩文名称为“Ga-Neun-mul-baem”，由纪万昌等人建立。(2012年)。
Three leptocephali (22.2, 22.7, 56.0 mm in total length) collected from the East/Japan Sea were identified by morphological and genetic analyses as belonging to the genus Scolecenchelys (Anguilliformes, Ophichthidae). Morphologically, the specimens were characterized by 148-158 myomeres, 10 gut swellings, dorsal fin origin above middle of the body, and 6 postanal melanophores between the anus and the caudal margin. An analysis of an 849-base pair 12S rRNA sequence of mitochondrial DNA showed that sequences are concordant with those of adult Scolecenchelys fuscogularis (genetic distance = 0.001). Furthermore total number of myomeres is consistent with the total number of vertebrae in adult S. fuscogularis. This study provides the first description of the morphological characteristics of S. fuscogularis leptocephali and their variations with size. The Korean name of S. fuscogularis is “Ga-neun-mul-baem”, established by Ji et al. (2012).
