  • The Korean nudibranch faunal study has been conducted since 2011 and five species including Dermatobranchus otome Baba, 1992, Mexichromis festiva (Angas, 1864), Noumea nivalis Baba, 1937, Hoplodoris armata (Baba, 1993), and Okenia hiroi (Baba, 1938) were newly reported with re-descriptions and figures. Also, Noumea purpurea Baba, 1949 was re-described with illustrations because previous records for this species were given without a description. Two congeneric species in the genus Noumea could be distinguished by ground color, dorsal markings, color of the mantle edge and gills, and mantle and dorsal marking. In addition, mitochondrial cytochrome c oxidase subunit I (COI) sequences of five species were provided for further molecular identification study. Consequently, a total of 43 species have been reported for the Korean nudibranch fauna.

  • A new gastrotrich species of the genus Dendrodasys (Dactylopodolidae) is described on the basis of specimens collected from sublittoral fine sandy bottoms at Uljin, East Sea and at Gujwa, the northeastern coast of Jeju Island, South Korea. Dendrodasys duplus is characterized by a triangular head with lateral lobes extending outward, two pairs of pestle organs posterior to the lateral cephalic lobes, a pair of anterior adhesive tubes, the absence of dorsal, lateral and ventral adhesive tubes, large posterior adhesive tubes arising from the anterior third of the caudal peduncle, and paired testes of different lengths. The genus Dendrodasys is recorded for the first time in East Asia.

  • The first zoea of Camptandrium sexdentatum is described for the first time with a digital image of live zoeas. An ovigerous crab of C. sexdentatum was collected at the muddy sand flat in Namhaedo Island on 2 June 2012 and hatched in the laboratory on 6 June 2012. In Camptandriidae, the first zoea of C. sexdentatum is distinguished from the first zoeas of Cleistostoma dilatatum and Deiratonotus cristatum by having no dorsal and lateral carapace spines, an abdomen significantly broadened posteriorly, and a subovoid telson without forks. Especially, the finding of a subovoid telson without forks is the first report in brachyuran zoeas.

적조생물구제농도의 Sodium Hypochlorite(NaOCl)의 노출에 따른 조피볼락 및 바지락의 조직학적 영향 (Histological Effect of Sodium Hypochlorite (NaOCl), Exposed at Red Tide-killing Concentrations, in Rockfish and Little Neck Clam)

  • In a previous study by Kim et al. (2000), sodium hypochlorite (NaOCl) has been demonstrated to be effective against algae that cause red tides. To secure the environmental safely of the chemical in practical use, effect of NaOCl, at concentrations required for algicidal activity, on the histology of rockfish and little neck clam was examined. When the animals were exposed to NaOCl at concentrations of 0.5 or 2ppm for 1 hr, there was no exposure-associated histological change in either animal. As the experimental exposure condition was set in consideration of the use, our results provide safety information necessary for practical application to marine fields.

  • 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.

  • 1994년부터 주로 한국의 조간대 해조류 및 아조하대 바닥 퇴적물을 걸러 채집하여 보관중이던 Thalestridae과의 갈고리노벌레류를 재검토한 결과 Phyllothalestris sarsi Sewell, 1940와 Dactylopusia falcifera Willey, 1935의 2종을 추가로 동정하였다. 이 종들은 태평양에서 처음으로 보고되는 종이다. 2종 모두 원기재가 부족하여 한국산 표본을 재료로 하여 재기재를 하였고, 근연종과의 형질비교 및 변이성 등에 관하여 고찰하였다.

  • The Conus Linnaeus, 1758 is a large genus of marine gastropod mollusks belonging to the family Conidae. The Conus species are mostly distributed in the tropical waters of the world, and they are especially abundant in the Indo-West Pacific region. To date, more than 600 species, most of which are predatory species, have been named worldwide in this genus and only six species have been recorded in the Korean waters. Conus sponsalis Hwass in Brugui$\grave{e}$re, 1792 was collected from Jeju Island and identified as a new Korean record. In this study, we report a description of the shell morphology of the species.

  • The present census on freshwater bryozoans in the Han River, Geum River and in lentic water bodies in Gangwon Province revealed three gymnolaemate species. Two of them-Hislopia prolixa Hirose and Mawatari, 2011 and Victorella pavida Saville Kent, 1870 were recorded for the first time from South Korea. Paludicella articulata (Ehrenberg, 1831), on the other hand, had already been documented from a few sites since 1941. The bryozoans, all belonging to the order of Ctenostomata, were found on a variety of substrates in freshwater (H. prolixa and P. articulata) and brackish habitats (V. pavida). Hislopia prolixa had recently been established as a new species and this is the first record for an occurrence outside of Japan, where it had been newly described from Lake Biwa and nearby satellite lakes.
