  • Actiniarians were collected from the rocks and sand bed of Jejudo Island, Ulleungdo Island, and Wangdolcho in Korean waters from 2004 to 2009. They were classified as two species of two families belonging to the suborders Endocoelantheainea and Nynantheae. Especially, suborder Endocoelantheainea, with distinct development of mesenteries, was firstly added to Korean athenarian fauna with the species, Halcurias carlgreni McMurrich, 1901. Calliactis polypus (Forsk$\aa$l, 1775) showing the commensalism with hermit crab, was easily distinguished from C. japonica by external features and the composition of cnidae. These two species were described in detail with tables and figures.

  • Six species, four genera belonging to two families of antipatharians have been reported in Korea. In the present study, the major specimens were collected from the coastal areas of Jejudo Island from 2005 to 2006, and the other ones which have been deposited in the Natural History Museum and the Department of Life Science, Ewha Womans University during the period from 1965 to 2004 were reexamined. As a result of this work, two species, Cirripathes spiralis and Stichopathes filiformis, are newly recorded to Korean antipatharian fauna.

  • 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.

  • The zoantharians and ceriantiparians known from the Korea Strait are 21 species, 16 genera, 10 families in 3 orders, of which 6 species are newly recorded to the Korea Strait fauna. Three species of them are new to Korean waters: Flosmaria mustsuensis, Hormathia andersoni and Verrillactis paguri. The specimens were collected from 34 localities of Korea Strait from 1984 to 1991.

  • The Korean scleractinians examined in the present study are seven species in five families . They have six kinds of cnidae ; atrichous isorhizas, basitrichous isorhizas, holotrichous isorhizas, microbasis p-mastigophores, microbasic b-mastigophores and spirocysts, of which the holotrichous isorhizas, microbasic p-mastigophores and spirocysts are distributed in all species. The atrichous and basitrichous isorhizas are present very rare in Korean scleractinians. Especially the microbasic p-mastigophores are common in most parts of all species.

  • The antipatharians in Korea were known with three species and two genera belonging to family Antipathidae. In the present study, three species, Antipathes densa, A. grandiflora, and A. dubia, have been newly recorded to Korean antipatharian fauna with the samples collected from Jeju-do during the period from 2003 to 2005. The description was mainly based on the habitat, the branching mode of corallums, the size and arrangement of polyps and spines on the axis, and also the types of cnidae. They had three kinds of cnidae: spirocyst, basitrich, and microbasic p-mastigophore. Spirocysts and basitrichs were distributed at tentacles and microbasic p-mastigophores were mainly at septal filaments.

  • The tube anemone, Cerianthus filiformis Carlgren, was collected from nine localities in the Yellow Sea and the Korea Strait (the South Sea). Populations at different localities showed color variations in tentacles from pale brown to violet. This species is redescribed here because it shows the color variation and the association with the phoronid, Phoronis australis, which was newly recorded from Korean waters. The phoronid has black to purple tentacles shaded with the same color as the cerianthid's tube for mimicking.

  • The stony corals known from Korean waters are 24 species , 15 genera, 7 families in 5 suborders, of which 7 species are newly recorded to the Korean scleractinian fauna ; Montipora trabeculata, Oulangia stokesiana miltoni, Goniocorella dumosa, Dendrophyllia arbuscula, D.boschmai cyathohelioides, D. micranthus, and Rhizopsammia minuta mutsuensis. They were collected from 35 localities of southern Korea from 1969 to 1986. For the geographical analysis, the coastal waters of Koarea are divided into four regions ; the Yellow Sea, the Korea Strait, the Cheju Island area and the East Sea (Sea of Japan) . These are based on the species diversity , the geographical distribution form, and the community coefficient, Korean scleractinians consists of 8 temperate zone forms(33.3%, Te) and 16 tropical forms(66.7%, Tr) . Concerning the distribution in each region, 3 spp. (2 Te, 1 Tr) occur in the Yellow Sea, 9 Spp. (5 Te, 4 Tr) in the Korea Strait, 16 spp.(4 Te, 12 Tr) in the Cheju Island area and 5 spp. (2 Te, 3 Tr) in the East Sea. The communicty coefficient between the Korea strait and the East Sea is the highest (0.596), and that between the Yellow Sea and the Cheju Island area is the lowest(0).
