  • A faunal study on the marine amphipods at eight sites of the continental shelf region in the Southern Sea, Korea was conducted from 16-17 August 2022. In this study, 26 amphipod species in 19 genera and 14 families were found. Among these 14 families, the family Ampeliscidae with six species showed the highest abundance, followed by the family Caprellidae with five species. Amphipods were collected using conical nets, MOCNESS nets, SM grabs, and trawls. When using the SM Grab for collecting benthic sediment, 15 out of a total of 26 amphipod species were surveyed, indicating the highest diversity of amphipod species. Out of the total 26 species, four identified species (Ampelisca pygmaea Schellenberg, 1938; Byblis longiflagelis Ren, 1998; Caprella iniquilibra Mayer, 1903; Primno latreillei Stebbing, 1888) and five unidentified species(Themisto sp., Liljeborgia sp., Dulichiella sp., Cranocephalus sp., Primno sp.) are newly recorded in Korean fauna. These newly recorded species are fully illustrated and compared with related species. We provide a list amphipod fauna in Southern Sea of Korea including figures and tables.

  • This study analyzed the species composition and density of a macrobenthic community according to variations in the thermal discharge volumes of a nuclear power plant before, during, and after the shutdown of the nuclear power plant during two periods. In this study, 369 macrobenthic fauna species were collected, and their mean density was 1,712 ind. $m^{-2}$. The number of species and diversity of macrobenthic fauna decreased with distance from the thermal discharge area, regardless of whether the nuclear plant shutdown or not. Many macrobenthic taxa appeared near the thermal discharge area, but polychaetes species were more prominent in outer areas than at the discharge area. The density of macrobenthic fauna decreased with distance from the thermal discharge area during a plant shutdown in the fall of 2011, but increased, except at two sites, near the discharge area in the winter of 2012. Cluster analysis indicated that the spatial distribution of the macrobenthic community changed in areas near the nuclear power plant after a shutdown period; that is, the station group I, in areas near the nuclear power plant, became narrower after the shutdown, but it recovered to previously occupied areas after the nuclear power plant began operating again. Opportunistic species, such as the polychaetes Lumbrineris longifolia (= Scoletoma longifolia) and Mediomastus californiensis, which were present in high densities near thermal discharge areas, decreased after the shutdown but recovered after the plant re-opened. The number of species and diversity of the macrofauna and the density of dominant species showed a significant correlation with temperature, except in winter periods. The results of this study revealed that changes in the amount of thermal discharge before and after the shutdown of a nuclear power plant could exert an influence on the structure of macrobenthic community within the thermal discharge areas depending on the season.

  • During the course of studying the helminth fauna from the fishes of the Korean coastal waters, two bucephalid species, Dolichoenterum longissimum Ozaki, 1924 and Prosorhynchus aculeatus Odhner, 1905, were collected from the alimentary canal of the conger eel, Conger myriaster. D. longissimum was characterized by having the ovary between the testes, and 7-8 horn-like projections on the ventral side of rhynchus. P. aculeatus was distinguished from the other species by the location of the mouth or the opening position of the excretory vesicle. These two bucephalid digeneans are new to the Korean fauna.

  • This study aims to clarify the diversity of bryozoans which were collected from Seogwipo waters in Jeju Island, Korea. A total of 78 species has been reported from Seogwipo waters so far. In the present study, 63 species were found from nine sites of Seogwipo waters from 2008 to 2012, including six newly added species to the Korean bryozoan fauna and twelve species new to Seogwipo waters. As a result of this study, the bryozoans from Seogwipo waters were turned out to be 96 species, 64 genera, 42 families, three orders and two classes.

  • In 2017, during a survey of the anthozoan fauna in the Hallyeohaesang National Park in the South Sea, several Acanthogorgia specimens were collected from the subtidal zone. Through taxonomic analysis, one species, Acanthogorgia densiflora $K{\ddot{u}}kenthal$ & Gorzawsky, 1908, was found to be previously unreported from Korea, and was, therefore, newly added to the list of Korean anthozoan fauna. This species is distributed on the slopes of the rocky substratum between depths of 14 and 24 m. Including the findings from this study, ten species of the genus Acanthogorgia have thus been reported from the Korean waters until now.

  • Ten species of Galatheoidea (squat lobsters), belonging to two families, were collected in the Korean exclusive economic zone: Galathea balssi Miyake and Baba, 1964, Galathea orientalis Stimpson, 1858, Galathea pubescens Stimpson, 1858, and Galathea rubromaculata Miyake and Baba, 1967 belonging to Galatheidae; Bathymunida brevirostris Yokoya, 1933, Cervimunida princeps Benedict, 1902, Munida caesura Macpherson and Baba, 1993, Munida japonica Stimpson, 1858, Munida pherusa Macpherson and Baba, 1993, and Paramunida scabra (Henderson, 1885) belonging to Munididae. The present study comprises the morphological description of these ten species, including drawings and color photographs, a brief review of their regional records, and a key for their identification. Although all species are common in Japanese waters, G. balssi, G. rubromaculata, B. brevirostris, C. princeps, M. caesura, and M. pherusa are new to Korean marine fauna.

  • In 2020, during a survey of cnidarian fauna around Chuja-do locating in the northern part of Jeju-do, Korea, several hydroids were collected from the subtidal zone by SCUBA diving. Through taxonomic examination, one unrecorded species, Hydrodendron stechowi Hirohito, 1995, was found in Korea. It was newly added to the list of Korean hydrozoan fauna. This species was discovered for the first time since its first report as a new species in Japan. Their vivid orange-colored colonies were attached to the sponge on rocky substrate between depths of 15 and 20 m. Thus, a total of five species belonging to genus Hydrodendron, including the species reported in this study, have been reported in Korean waters so far.

  • A parasquillid stomatopod, Faughnia haani(Holthuis, 1959), collected from Jeju Island, is reported for the first time in Korea. This species is characterized by the presence of obtuse anterolateral angles of carapace, median and three pairs of longitudinal carinae on telson, and crenulate inner margin of uropodal protopod. In this paper, a detailed description and illustrations are provided. As a result of this study, the geographical distribution of the present species is extended and 15 species of stomatopods including this species are now recorded in Korean fauna. The specimen examined herein was deposited in the National Institute of Biological Resources(NIBR).
