A new species of the genus Albula family Albulidae is described based on five specimens collected from Korea and Taiwan. Its scientific name, koreana sp. nov., derived its type locality (Korea). We compared nov. with similar species, A. argentea Fiji (seven specimens), using morphological molecular methods. differs morphologically in tooth patch distributions mesopterygoids parasphenoid. The patches are distributed more anteriorly than those parasphenoid On other hand, anterior end almost...

A single specimen of the genus Sillago, collected from Gwangyang, Korea, in May 2009, is characterized by XI first dorsal fin spines, 3 or 4 rows melanophore pattern along second membrane, and a darkish posterior margin caudal fin. Our was identified as Sillago sinica reported new species; this identification confirmed mitochondrial DNA cytochrome oxidase subunit I sequences, which show that our corresponds to S. (d=0.000) differs congeneric species parvisquamis (d=0.170). Comparisons Korean...

A specimen of the blue-lined octopus, Hapalochlaena fasciata (Hoyle, 1886) was collected from a tidal pool on southern coast Jeju Island, Korea, 10 September 2015 and identified by DNA barcoding. This species is characterized its blue middle lines dorsal lateral mantle head, with development numerous small papillae mantle, arms. molecular analysis mitochondrial cytochrome oxidase subunit I gene showed that belonged to H. 98.8% sequence similarity. The proposed Korean name...

Three specimens of Cynoglossidae larvae were collected from the southern Korean Sea in May and August 2009, identified using morphological molecular analysis. Specimens divided into two groups based on number elongated dorsal fin rays top head: sp. A was defined as having rays, while B possessed a single ray. One specimen A, post-larva with notochord length (NL) 5.8 mm thought to be Cynoglossus joyneri larva presence 115 pterogiophores, 85 anal 50 myomeres. Two B, 4.1 NL 11.3 juvenile,...

Abstract To clarify the taxonomic status of five specimens Albula collected from Korea and Taiwan (Albula sp.), genetic differences among them other congeneric species were investigated based on mitochondrial DNA cytochrome b sequences. All sp. showed identical haplotypes strongly supported a monophyletic group phylogenetic analysis. The between ten ranged 0.100 to 0.164. These values almost equal or exceeded interspecific latter (0.038–0.206). Morphological comparisons another four...

The re-identification of two Korean tonguefishes, Cynoglossus interruptus and Symphurus orientalis, was carried out using eight specimens collected from waters in 2007 2013. C. is characterized by having a single row scales between rows connected to the supraorbital line middle lateral line, 107–113 dorsal fin rays, 86–89 anal 53–55 vertebrae. S. orientalis 1-2-2-2-2 ID pattern, 97–100 83–89 52–55 Molecular analysis mitochondrial DNA Cytochrome...

Species identification is important in natural science and should be precise. Six specimens of juvenile Pseudoblennius were collected from the eastern coastal waters Korean Peninsula Jeju Island 2016–2017, identified for first time using DNA barcoding based on mitochondrial cytochrome oxidase subunit I sequences. analysis supported three adult species genus (P. cottoides, P. marmoratus, percoides) being quite distinct each other. completely identified: two as cottoides; more marmoratus;...

A new species, Eulophias koreanus, belonging to the family Stichaeidae, suborder Zoarcoidei, is described on basisof five specimens (70.7–160.7 mm in standard length) collected from southern sea of Korea. The species differsfrom only two known congeneric tanneri and owashii, which are endemic Japan. Eu-lophias koreanus readily distinguished E. by numbers anal-fin rays (102–103 vs. 75 tanneri)and caudal-fin (9–10 7). more similar owashii than tanneri, but differs theformer number vertebrae...

Seventy-six species of fishes, representing 60 genera and 34 families, were recorded from tidal pools on Jeju Island, southern Korea. The major families in terms the Gobiidae (11 species), Pomacentridae (8 Blenniidae (6 Labridae (5 species). Thirty-nine classified as tropical, 26 temperate 11 subtropical.

Abstract Four specimens of unknown Coilia sp. were collected for the first time from Yellow Sea in 2008 and compared with mystus nasus. showed similar morphology to C. nasus, but differed that its tail was considerably shorter. We conducted an analysis morphological genetic characteristics effort clarify taxonomic position In counts measurements, well distinguished nasus by number scutes (42–44 vs. 40–45 45–55 nasus), ratio dorsal base length head (43.4–47.6 37.9–47.6 33.0–41.0), eye...

Crenimugil crenilabis (Forsskål Citation1775) is a fish species newly identified with molecular analysis and reported in Korea for the first time. A single specimen of C. was collected from tidal pool on southern coast Jeju Island, August 2018. This characterized by several rows papillae both lips, no notch mouth corner, presence 36 lateral-line scales, 24 vertebrae. The present morphologically similar to another seven mugilid Korea, but mitochondrial DNA COI gene revealed that it almost...

The Fish Collection Project collected 356 fish species from the Southern Sea of Korea during 2010-2012, 55 more than previously collected. fishes belonged to 3 classes, 29 orders and 128 families. 5 dominant orders, Perciformes, Scorpaeniformes, Pleuronectiformes, Tetraodontiformes, Clupeiformes, accounted for ~80% identified species. Additionally, 126 were first time, while 85 that had been found in previous collections not seen. variety may be influenced by its unique oceanographic...

A single specimen of the whitespotted frillgoby, Bathygobius coalitus (Bennett, 1832), was collected from Jeju-do, Korea, in October 2020. The species is characterized by absence a flap on nostril, extension anterior tip predorsal scale beyond posterior margin preopercle, and pectoral fin with four upper rays free membrane, each divided into two branches. Mitochondrial DNA Cytochrome Oxidase subunit I analysis revealed that corresponds to B. (99.8% similarity), rather than any three...

The length–weight relationships (LWRs) of three endangered tidal pool fishes, Spratelloides gracilis (Temminck & Schlegel, 1846), Atherion elymus Jordan Starks, 1901, and Enneapterygius etheostomus (Jordan Snyder, 1902), from Jeju Island, Korea, were analysed. A total 280 specimens sampled using hand nets (mesh size 1 mm) or by dredge 5 July 2015 to 2016. This study provides the first LWRs for two species, a new LWR one maximum length data species.

Six specimens of Bathygobius hongkongensis were collected for the first time from eastern coast Jeju Island, Korea, in September–November 2017. This species is characterized by a pectoral fin with free rays and division dorsalmost ray into three branches; lower jaw mental frenum; an anterior nostril tiny flap. similar to B. fuscus but differs having more rays. The new Korean name proposed “Nam-bang-mu-nui-mang-duk.”

The intertidal zone of Jeju Island, Korea, is characterized by well-developed volcanic rocks with high wave action. During low tide, numerous small tidal pools are formed on the rocky zone, which provide shelter and habitats for benthic organisms. Previous investigation indicated that many species micromolluscans inhabit pools; however, only a few studies have reported ecology identification these microshells. In this study, we identified microgastropod, Ammonicera japonica Habe, 1972...

Here, we report the complete mitochondrial genomes of Sculpins species Gymnocanthus intermedius and herzensteini. The mitogenomes were determined to be 16,639 bp for G. 16,691 comprised 13 protein-coding genes, 2 rRNA 22 tRNA a non-coding region. We then used mitogenome data construct phylogenetic tree these two an additional three within order Scorpaeniformes.
