  • Three xanthid crabs, Liomera margaritata, Neoxanthops lineatus and Pilodius miersi, are described and illustrated for the first time in Korea. Liomera margaritata and N. lineatus are the first species of their genera to be found in Korea. The three species represent extensions of their previously known ranges and bring the number of known species of the xanthid crabs to 25 from Korean waters.

  • Sponges of the family Spongiidae are poorly known in Korean waters. This paper describes Hippospongia bergquistia n. sp. of the family Spongiidae (Demospongiae: Dictyoceratida) collected from Moselpo, Jejudo Island, Korea in 2007. This new species has a cavernous construction, rare pseudo-tertiary fibre, and rare primary fibres.

  • The first zoeal characters of plagusiine crab Plagusia dentipes De Haan, 1835, belonging to the family Grapsidae, is described and illustrated in detail based on laboratory-hatched material from an ovigerous female collected from Bomok, Seogwipo in the Jejudo Island. Morphological comparison is made with previous description of Plagusia dentipes from Japan. The first zoea of Plagusia dentipes can be readily distinguished from those of two species of Plagusia chabrus and Plagusia depressa by having 2 aesthetascs and 3 simple setae on the antennule, and 8 setae on the coxal endite of the maxilla.

  • A female crab of Xenocarcinus conicus (A. Milne Edwards, 1865) was collected from Munseum, Jejudo Island. The genus Xenocarcinus is recorded newly in Korean brachyuran fauna. The present specimen has broader and shorter rostrum and eleven sharp teeth on the inner border of dactylus of the first ambulatory leg. Korean epialtid fauna now consists of eight species of four genera.

  • Chelonaplysilla supjiensis n. sp. belonging to family Darwinellidae was collected from Jejudo Island, Korea in 2008. C. supjiensis n. sp. is closely to C. noevus in surface structure and skeleton, but differ in surface, sandy reticulation mixed with many spicule detritus. This study is a new record of genus, family and order in Korea.

  • A planetary boundary layer model has been modified to study the feasibility of siting the wind energy conversion systems over Jejudo island. Our objective is to demonstrate a numerical model that is simple enough to be economical in terms of computational cost and contains most of the mesoscale processes occurring in the planetary boundary layer at the same time. Simulated fields of atmospheric parameters are compared favorably with available climatological data and interpreted in terms of physical phenomena occurring.

  • The sessile ctenophores, Lyrocteis imperatoris Komai, 1941 were collected for the first time from Garinyeo, offshore Seogwipo of Jejudo Island by SCUBA diving on June 18, 2009. This species distributed in West North Pacific was newly recorded in Korean waters. Its embryos in various developmental stages were observed in the internal brood chamber.

  • A pagurid crab carrying half of a bivalve shell was collected from Jejudo Island and identified as Porcellanopagurus nihonkaiensis. A diagnosis with illustrations of this specimen is presented. Although, Komai and Takeda (2006) reported this species as rare and known only from Japan, its range is now extended to Korean waters. At present, it is the only species of the genus Porcellanopagurus represented in Korean waters.

  • Some hydroid specimens were collected from 10-14 m deep of Munseom (Jejudo Is.) on 22 June 2007, and from 20-25 m deep of Nagokkkottdongsan (Uljin) on 10 Jan. 2008 by SCUBA diving. Among the identified species, the following three species, Solanderia spinosa (Carter, 1892), Lafoea dumosa (Fleming, 1828) and Rhizocaulus verticillatus (Linnaeus, 1758) were turned out to be new to the Korean fauna.
