  • The synaphobranchid eel, Dysomma anguillare was redescribed on the basis of a specimen collected from the Yellow Sea, Chollabuk-do, Korea. The D. anguillare was characterized by many fleshy plicae at the front of upper and lower jaws, dorsal fin originated in slight advance than pectoral fin base, degenerated eyes, very short trunk and long tail, anus located below near tip of pectoral fin and no scales.

  • A checklist of snake eels (Ophichthidae) from Korea is presented including information, such as synonyms, distribution, occurrence records and key to species of 7 genera and 14 species. Also, we suggest change of the Korean names for the snake eels (Ophichthidae) "Ba-da-baem-gwa" to "Ba-da-baem-jang-eo-gwa", and it's members, because Korean names of snake eels (Ophichthidae) is similar to those of sea snake (Hydridae).

  • 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).

New Korean Record of Highfin Moray Gymnothorax pseudothyrsoideus (Anguilliformes: Muraenidae) from Jeju Island (한국 제주도에서 채집된 곰치과(Muraenidae) 어류 1 미기록종, Gymnothorax pseudothyrsoideus)

  • A single specimen of Gymnothorax pseudothyrsoideus (424.0 mm TL) belonging to the family Muraenidae, order Anguilliformes, was collected from Jeju Island, Korea, for the first time. The specimen is characterized by jaws closing completely, canine teeth on jaws, teeth not exposed when mouth is closed, ovoid posterior nostril, and body color ranging from yellowish brown to brownish with small dark spots aggregating to form larger spots that from approximately four irregular rows along the body. A comparison of mitochondrial DNA 16S rRNA sequences indicated that this specimen corresponds well with G. pseudothyrsoideus (K2P distance, d=0.002) but differs from other Gymnothorax species (11.9-13.7%). Therefore, the new Korean name "Geu-mul-nun-gom-chi" is proposed for the species G. pseudothyrsoideus.

  • Leptocephali of the genus Saurenchelys in the family Nettastomatidae were collected from the coastal area of Pohang, Korea and described as the first record from Korean waters. S. stylura and S. lateromaculatus are characterized by two intestinal swellings, the pattern of pigments in the notochord, and by smaller pectoral fins than those of other genus. They are very similar to each other but they are distinguished by the pattern of pigments in the notochord and the intestinal swellings.

  • A taxonomic review of 6 genera and 10 species in the family Ophichthidae was carried out based on specimens from the adjacent waters of Korea. The number of vertebrae distinguished the species of each genus: Ophisurus macrorhynchos (201~209), Ophichthus rotundus (178~183), Pisodonophis zophistius (179~182), P. cancrivorus (153~164), Echelus uropterus (152~158), Muraenichthys gymnopterus (155~156), Ophichthus evermanni (150~154), Brachysomophis porphyreus (137~148), Ophichthus urolophus (135~138), Ophichthus asakusae (124~134). Snout length in head length distinguished the 6 genera: Ophisurus (27.2~31.2), Echelus (18.0~27.7), Ophichthus (12.3~21.5), Pisodonophis (16.5~20.8), Muraenichthys (11.4~11.9), Brachysomophis (9.1~9.4). A key to the 6 genera and 10 species of the family Ophichthidae from the adjacent waters of Korea is provided.

  • A single specimen of the ophichthid Muraenichthys gymnopterus (254.6 mm TL) was collected from the middle Yellow Sea off Incheon, Korea. It represents the first record of the species, the genus, and the subfamily from Korea. This species is characterized by the following combination of characters: a constricted midlateral gill opening; dorsal fin origin before anus, closer to the anus than to the gill opening; blunt teeth, jaw teeth in bands, and multiserial dentition; third preopercular pore present; single infraorbital pore between anterior and posterior nostrils; brownish colour; depth and width of gill opening 43.2 times and 33.7~65.3 times in total length, respectively; eye diameter 15.0~31.0 times in head length and total vertebrae 154~161. New Korean names are proposed, "Gaet-mul-baem-a-gwa" for the subfamily Myrophinae, "Gaet-mul-baem-sok" for the genus Muraenichthys, and "Gaet-mul-baem" for M. gymnopterus.

The species is characterized by a pointed, hard, sponge-like tail tip without a caudal fin and 126-132 total vertebrae. We propose a new Korean name, "Je-ju-ba-da-baem" for the species.
