Abstract
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).
