한국 제주도에서 채집된 곰치과(Muraenidae) 엽상자어 2개체 (전장 36.2~69.2 mm)를 대상으로 mtDNA 12S rRNA 724 base pair 염기서열을 분석한 결과, 한국 통영에서 채집된 나망곰치(Gymnothorax minor) 성어와 100% 일치하였다. 나망곰치 엽상자어는 전체 근절수가 137~139개, 등지느러미 앞 근절수가 32개, 항문앞 근절수가 82~86개, 전장에 대한 체고가 10% 이상인 형태적 특징을 나타내었다.
Two leptocephali (36.2~69.2 mm in total length) of the family Muraenidae were collected off Jeju Island, Korea. They were identified using 742 base pairs of mitochondrial DNA 12S rRNA sequences, and their morphological description were presented. The two leptocephali were identified to Gymnothorax minor based on genetic distance (d=0.000), being well consistent with that of G. minor adult collected off Tongyeong. Gymnothorax minor leptocephali are characterized by morphological combinations: total myomeres 137~139, predorsal myomeres 32, preanal myomeres 82~86, body depth in total length more than 10%.
