  • Three species of endosymbiotic dinoflagellates, zooxanthellae, are investigated from six host species of anthozoans from Korea. Three unrecorded endosymbionts species are Symbiodinium kawagutii, Symbiodinium microadriaticum, and Symbiodinium sp. Symbiodinium kawagutii Is associated with Alveopora japonica, Anthopleura japonica and Parasicyonis actinostoloides. Symbiodinium microadiraticum is found in Anthopleura kurogane and Parasicyonis sp. Unlike the former two symbionts, Symbiodinium sp. is associated with Anthopleura midori.

  • The faunal survey on anthozoans of Geojedo Island was conducted from 17 localities of the adjacent waters of Geojedo Island during the period from February 1995 to Januray 1998. As a result, 39 species, 25 genera, 21 families, 7 orders, 3 subclasses in class Anthozoa were identified. Two of them, Callicatis japonica and Nemanthus nitidus are new to the Korean fauna.

  • Systematic relationship of 13 species representing seven orders of anthozoans, and one hydrozoan as an outgroup, were investigated. Distance and parsimony methods were used to analyze nucleotide sequence data obtained from the 18S rDNA. The inferred phylogeny indicates that two orders, Ceriantharia and Antipatharia within subclass Ceriantipatharia, are not closely related to each other. Instead, the former appears to be the most ancestral group among anthozoans but the latter is more closely related to order Actiniaria within subclass Zoantharia. The result also indicates that the actiniarian may not be a monophyletic group, because Epiactis Japonica is related more to order Scleractinia. Subclass Octocorallia appears to be a monophyletic group, within which order Pennatulacea diversed at first, and then orders Alcyonacea and Gorgonacea diversed later.

  • The partial nucleotide sequences of 185 ribosomal RNA gene were compared for six cnidarian species (one belongs to class Hvdrozoa: Coryne pusilla. Five belong to class Anthozoa: Beflonella rigida from Octocorallia; Anemonia sulcutu, Anthopfeura kurognne, An thopleura midori from Hexacorallia: Cerianthus filiformis from Ceriantipatharial. The aligned sequence data were used to test the hypothesis on the anthozoan phylosenv by using the distance matrix method and parsimony method. The phvlosenetic inferences resulting from these methods indicate that the anthozoan is a monophvletic group and support the three subclass scheme (Octocorallia, HexBcorallia, Ceriantipatharial within class Anthozoa. The result also indicates that ceriantipatharian is more primitive than the other groups and that family Actiniidae is a monophvletic group within the anthozoan. However, the present analysis does not clearly indicate the phvlogenetic relationships of species among genera.

  • Two porcelain crab species, Aliaporcellana pygmaea (De Man, 1902) and Lissoporcellana nakasonei (Miyake, 1978), are reported here for the first time from Korean waters based on specimens collected from Jeju Island, Korea. The genus Aliaporcellana Nakasone and Miyake, 1969, and Lissoporcellana Haig, 1978 are also reported here for the first time in Korea. Aliaporcellana pygmaea has a wide distribution. The specimen reported here is the most northern record of this species. While, Lissoporcellana nakasonei, associated with anthozoans, was known for distributing range from New Caledonia to southern Japan. As a result, the distribution rage of L. nakasonei is changed to Korea. Now, 12 species of porcelain crabs have been reported in Korean waters.

  • A study on the classification of the Korean anthozoans is based on the materials which were collected during the period from October 1963 to May 1975 in the coastal seas of the South Sea and the East Sea of the South Korea. The results of the identification were turned out to be eight species, five genera, three families and one order. They are all unrecorded species in Korean anthozoan fauna. The newly recorded species are as follows: Family Alcyoniidae: 1. Bellonella rubra Brundin, 1896; 2. B. rigida Putter, 1900; 3. B. unicolor (Kukenthal, 1906); 4. Alcyonium gracillimum Kukenthal, 1906; Family Nephtheidae: 5. Paraspongodes spiculosa (Kukenthal, 1906); 6. P. hirotai (Utinomi, 1951); 7. Dendronephthya pectinata (Holm, 1985); Family Nidaliidae: 8. Siphonogorgia dofleini Kukenthal, 1906.

  • This study was conducted to investigate the recruitment pattern of sessile organisms on the artificial substrates of PVC in Jangmok Bay, Geoje Island, southern coast of Korea. Five PVC plates were submerged from March to October, 2007 at one month interval, and two plates were retrieved after one month. The dominant recruiters were a green algae, Entermorpha prolifera in March, Mytilus galloprovincialis in April, M. galloprovincialis and Styela plicata in May, S. plicata and Bugula sp. in June. During August, Balanus amphtrite and anthozoans were dominant recruiters, and a serpulid worm, Hydroides ezoensis in October. There was a clear specific recruiting period of sessile faunas depending on their reproduction cycles in a sheltered embayment like Jangmok Bay.
