A single specimen (522.0 mm in total length) of the family Muraenidae, collected from the waters off south-western Jeju-do Island in November 2021, was identified as Echidna nebulosa on the basis of morphological and molecular methods (DNA barcoding). This species is characterized by several morphological traits as follows: 10 rounded molar, median intermaxillary, and vomerine teeth; 4 predorsal vertebrae, 50 preanal vertebrae and 123 total vertebrae; and a pale background color with two rows of 17-20 blackish brown starry blotches along the head and body. As this is the first record of E. nebulosa in Korea, we propose the new Korean names, "Dung-Geun-Ni-Gom-Chi-Sog" for the genus Echidna, and "Beol-Kkok-Gom-Chi" for E. nebulosa.
