Aidanosagitta crassa, a key species in South Korea’s coastal waters, exhibits three morphological types: Type C with a collarette-containing trunk, Type N lacking a
collarette, and an intermediate Type I. Limited research studies have been conducted on their ecological patterns, prompting this study to elucidate seasonal occurrence patterns of A. c...
The hydrographic variability in the fjords of Svalbard significantly influences water mass properties, causing distinct patterns of microbial diversity and community composition between surface and subsurface layers. However, surveys on the phytoplankton-associated bacterial communities, pivotal to ecosystem functioning in Arctic fjords, are limite...
This study assessed the taxonomic statuses of three lesser-known Magelona F. Müller, 1858 species collected from intertidal to sublittoral habitats in Korean coastal waters, basing identification on morphological features and comparing them with their closest congeners. We present a comprehensive description and illustration of taxonomically signif...
Simple Summary
This study assessed behavior, heart rate, and wound healing in flounder to evaluate the appropriate recovery period after surgical implantation of a bio-logger. Compared to the non-operated fish, the operated fish exhibited stable levels after the 3rd 4th day in Experiment 1 (22 °C). Statistical analyses based on heart rate in Experi...
An undescribed species belonging to the family Eunicidae was detected in a sublittoral habitat of the southern coast of Korea. This Korean eunicid species was initially thought to belong to the genus Lysidice based on its general appearance, including the absence of prostomial lateral palps and peristomial cirri. However, a more detailed characteri...
Since the first record of chaetognaths (arrow worms) reported from Korean waters by Molchanov in 1907, three families, 12 genera and 21 species have been additionally described. Eighteen of the 21 recorded species have been reported under scientific names different from the latest taxonomic system. This study aimed to address this issue by conducti...
Chitin, one of the most abundant biopolymers in nature, is a crucial material that provides sufficient rigidity to the exoskeleton. In addition, chitin is a valuable substance in both the medical and industrial fields. The synthesis of chitin is catalyzed by chitin synthase (CHS) enzymes. Although the chitin synthesis pathway is highly conserved fr...
To understand the environmental factors affecting the spatiotemporal distribution of copepods, sampling was conducted seasonally in a small mesotidal inlet and estuary located in Doam Bay of southwestern Korea. The study area was divided seasonally into two or three station groups (estuarine, mixed, and coastal) by a cluster analysis and non-metric...
Heterorhabdus papilliger (Claus, 1863) is newly reported from the Tsushima Warm Current realm of the southern Korean waters. Its morphological diagnostic characteristics generally agreed well with the original description and the previous records of H. papilliger. The female of H. papilliger can be recognized by the genital somite, which in lateral...
Dasybranchus geojedoensis sp. nov., obtained from the soft sublittoral bottom in southern Korea, is described as a new species. This new species of Dasybranchus is easily distinguishable from its congeners by the protruded parapodial lobes in the final few thoracic chaetigers. Dasybranchus geojedoensis sp. nov. closely resembles D. bipartitus (Schm...
Three undescribed species of Heteromastus Eisig, 1887 were collected from intertidal to sublittoral habitats in western and southern waters of Korea. Heteromastus namhaensis sp. nov. is distinguishable from other congeners by the presence of hemispheric notopodial lobes in the posterior abdomen. Heteromastus gusipoensis sp. nov. closely resembles H...
Notomastuskoreanussp. n. , collected from the sublittoral muddy bottom of Korean waters, is described as a new species. The Korean new species closely resembles N.torquatus Hutchings & Rainer, 1979 in the chaetal arrangement and the details of abdominal segments, but differs in the position of genital pores and the absence of eyes. DNA sequences (m...
Two populations of new species are described for Hexapleomera Dudich, 1931 from the southeastern coast and Jeju island of South Korea (north west Pacific). The specimens were collected using a light trap set overnight at the entrance near a pier or harbour. Hexapleomera ulsana sp. n. is clearly differentiated from other species in the genus by the...

Leiochrides yokjidoensis sp. n., collected from the sublittoral muddy bottom in southern Korea, is de-scribed as a new species. The taxonomic status of the monospecific genus Pseudomastus has been a subject of controversy for many years, as its characteristics overlap those given in recent generic definitions of Leiochrides. The results of a compre...
To date, specimens belonging to the genus Capitella Blainville, 1828 collected from Korean waters have been identified as C. capitata sensu Eisig, 1887 for over 35 years, depending almost totally on the description of Paik (Bull Korean Fish Soc 13:89–92, 1980), but consisted of the capitellid species examined in this study. Although the characteris...
Two new species of Zeuxo Templeton 1840 are described from the western and southern coast of Korea (North West Pacific). Zeuxo gracilis n. sp. and Z. spina n. sp. belong to the “Z. normani species complex”. Zeuxo gracilis is distinguished from species within this complex by the following morphological combination in females: the spine row of the le...
Two new species of Leptochelia Dana, 1849 are described from the western coast of Korea. Leptochelia grandidentata n. sp. is similar to L. itoi and L. lusei characterized by pleonites 4 and 5 of subequal lengths and a uropod endopod with 4 articles but differentiated by a cheliped fixed finger longer than the dactylus and with 4 teeth along the inc...
Euchaetid copepods (Calanoida, Clausocalanoidea) were collected from the southeastern region of Korea and the East/Japan Sea
from June 2007 to August 2008. Seven species were found and redescribed in this study: five species from the genus Euchaeta (E. concinna, E. indica, E. longicornis, E. plana and E. rimana) and two species from the genus Parae...
In Summer 2008, a multidisciplinary survey was conducted onboard R/V Haeyang 2000 to understand plankton response to the three distinct physico-chemical settings that developed in the Ulleung Basin of the East Sea. Baseline settings of hydrographic conditions included the presence of the thin (, S>33.7) Ulleung Warm Eddy surface water centered at a...
