  • The bivalve molluscan fauna of Ulsan Bay, East Sea coast of Korea, is summarized, based on original and literature data. The fauna consists of 61 species belonging to 20 families. Seven species are identified only to genus level. Two species (Carditellopsis toneana (Yokoyama, 1922), Carditidae and Fulvia hungerfordi (G.B. Sowerby III, 1901), Cardiidae) are new records for the East Sea coast of Korea, and one species (Crenella decussata (Montagu, 1808), Mytilidae) is a new record for Korea. Biogeographically, Ulsan Bay's bivalve fauna is subtropical with a predominance of tropical-subtropical species, 21 species, or 39% of the total species number, subtropical, 14 species, or 26%, and subtropical-boreal (mostly subtropical-lowboreal), 11 species, 21%, totalling 86%. A remarkable feature of the Ulsan Bay fauna is the presence of tropical-subtropical species not found in Yeongil Bay but common in tidal flats and shallow waters of the Yellow Sea and the southern part of Korea. A cold water mass appearing off the southeast coast of Korea near Ulsan in summer seems responsible for the presence of boreal-arctic species in this area.

  • 새만금 방조제 공사에 따른 동물 군집변화를 분석하기 위한 기초자료를 얻고자 이 지역에 서식하는 연체동물상을 조사하였다. 생물상 조사는 2003년 8월 3일에서 5일, 8월 21일에서 23일 등 2회에 걸쳐 실시하였다. 조사결과 40과 88종의 연체동물이 채집되었으며, 문헌기록을 포함하여 새만금 지역에 서식하는 연체동물은 모두 48과 109종으로 밝혀졌다. 이 중 금번 조사에서 흰점줄박이고둥(Eurytrochus cognatus)을 포함한 34과 51종이 새만금 지역의 연체동물상에 새로이 추가되었으며, 더욱 정밀한 조사를 한다면 더 많은 종이 추가될 것으로 추측된다. 이 지역에는 희귀종과 상업적으로 중요한 연체동물이 다수 서식하고 있으며, 방조제 공사에 의해 막대한 영향을 받을 것으로 예측된다.

  • The high latitude scleractinian coral Alveopora japonica Eguchi, 1965 occurs in high density in the shallow rocky subtidal in Jeju Island, forming coral carpets. Despite its ecological role providing a unique habitat for other benthic organisms, the benthic fauna associated with the A. japonica coral carpet is poorly known. To identify fauna associated with the coral carpet, we explored three sites dominated by A. japonica and one control site on northwestern Jeju Island in May 2013. Using SCUBA, we collected A. japonica and the epibenthic mega-fauna associated with the colonies in 1×1 m2 and identified them to the species level. At a depth of 10 to 15 m, A. japonica colonies heavily covered the seafloor, forming a layer called a coral carpet, with a density of 94 (Keumneung-ri), 133 (Biyangdo), and 155 (Gwidok-ri) colonies/m2. Thirty-four molluscan species were identified from the four sites, including 20 bivalves and 14 gastropods. The coral carpets were enriched with sessile bivalves compared to the control site, as we identified twenty bivalve and eight gastropod species from the coral carpets. Most bivalve species associated with the coral carpets had tropical-subtropical affinities, while gastropods were mainly subtropical and subtropical-low boreal species. Leiosolenus lischkei M. Huber, 2010, in the family Mytilidae and Barbatia steamsi (Pilsbry, 1895), in the family Arcidae, were the two most abundant bivalve species in the coral carpet, L. lischkei being a borer, and B. stearnsi a nestler. The tropical to subtropical Pacific star shell Astralium haematragum (Menke, 1829)was the most abundant gastropod at the study sites. The bivalves and gastropods associated with the coral carpet were small-sized juveniles or sub-adults, suggesting that the coral carpet provides a micro-habitat for the bivalves and gastropods.

  • Up until now, we have identified 17 exotic species of Mollusca in Korea. These include Achatina (Lissachatina) fulica, Limax flavus, Limax marginatus, Deroceras reticulatum, Hawaiia minuscula, Zonitoides yessoensis, Zonitoides arboreus, Physa acuta, Pomacea canaliculata, Pomacea insularus, Crepidula (Crepidula) onyx, Mytilus galloprovincialis, Xenotrobus securis, Perna viridis, Argopecten irradians irradians, Pinctada fucata, and Pinctada margaritifera. Among them Achatina (Lissachatina) fulica, Pomacea canaliculata, Pomacea insularus, Argopecten irradians irradians, Pinctada fucata, and Pinctada margaritifera were intentionally introduced, whereas remainings were unintentionally introduced into Korean fauna. These foreign species can be divided into three groups on the basis of their habitats: A. fulica, L. flavus, L. marginatus, D. reticulatum, H. minuscula, Z. yessoensis, and Z. arboreus in terrestrial habitat; P. acuta, P. canaliculata, and P. insularus in fresh water; and C. onyx, M. galloprovincialis, L. fortuneikikuchii, P. viridis, A. irradiansirradians, P. fucata, and P. margaritifera in sea water. Taxanomically, 11 species belong to Gastropoda, whereas 6 species are classified to Bivalvia.

  • 한국동물분류학회 창립 20주년을 기념하기 위하여 진도의 무척추 동물상에 관한 공동조사가 수행되었다. 본 연구에서는 해산연체동물상을 연구하기 위해 2004년 6월 29일에서 6월 30일까지 3개 지점에서 조사를 실시하였고 그 결과 모두 37과 77종의 연체동물 종이 채집, 동정되었다. 이들 중 18과 26종은 진도지역에서 처음으로 채집, 보고되는 종이었으며, 특히 Onchidella kurodai (Taki, 1935) 검은콩갯민숭이는 한국 미기록종으로 밝혀져 이에 대한 기재와 도판을 작성하였다. 과거의 문헌기록 등을 포함하여 본 연구로부터 새롭게 기록된 종들을 종합하면 진도 및 인근 지역에서 보고된 연체동물은 현재까치 총 43과 115종이 된다. 생물지리학적 특성의 관점에서 볼 때, 진도에서 발견된 일부 복족류 종들 (Bittium craticulatum, Macroschisma dilatatum, Cantharidus japonicus, C. callichroa, Homalopoma sangarense, Crepidula onyx)은 제주지역을 포함한 한반도 남해 혹은 동해안 지역에서 이전의 연구를 통해 발견된 종들이었다. 진도지역에는 한반도 서해안 연안에 걸쳐 분포하는 연체동물의 많은 종이 서식하고 있다는 사실과 함께, 본 연구로부터 새롭게 얻어진 발견은 진도가 한반도의 남부 해안과 서부 해안 생물상이 중첩분포하고 있는 지역이라는 이전의 Kim and Kwon (1983)의 의견을 지지하는 또 하나의 증거가 된다. 향후 종합적인 생물상 연구가 수행될 경우 진도지역의 생물지리학적 특성에 관련된 새로운 정보는 물론. 보다 다양한 동물상이 추가될 것으로 기대된다.

  • The Turbinellidae shell Columbarium pagoda pagoda (Lesson, 1834), from the southern coast of Korea was recorded as new to the Korean molluscan fauna. The shell is typically solid and fusiform, with a well elongated spire and long anterior canal, and keel with a row developed spine. The protoconch is small, planorboid to depressed dome-shaped. The family Turbinellidae is reported from Korea for the first time.

  • The Federated States of Micronesia consists of four states of Yap, Chuuk, Pohnpei and Kosrae, which are located in the West Pacific Ocean. In order to investigate molluscan fauna of Kosrae Island, field survey was made twice from 21st to 30th of January, 2011 and from 6th to 17th of January, 2012 for four localities including 10 intertidal and 14 subtidal zones of Kosrae Island. The mollusk samples collected were identified based on their morphological characteristics, comprising a total of 120 species from 30 families through this survey. In this study, we provided species list and illustrations for 120 species identified, and combined these with the previous record, resulting in a total of 208 species from 47 families in Kosrae Island.
