  • 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.

  • 한국산 산호충류의 계통분류학적 연구의 일환으로 1970년부터 1985년까지 한국 황해 연안에있는 군락지와 흑산도에서 채집된 실꽃말미잘( Cerianthus filiformis)을 동정한 결과 한국미기록종으로 밝혀졌다. 1985년 4월에 채집된 개체는 몸속에 플라눌라 유생을 지니고 있었으며, 이들은 다양한 자포를 약간 갖고 있었고, 몸밖으로 나온 플라눌라 유생에서는 보다 분화된 자포를 갖고 있었다. 특히 성체에서는 체벽에 있는 자포 중 ptychocyst가 처고형성에 지주 역할을 함을 볼 수 있었다.

  • 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.

  • Some actiniarians were collected from the coasts of Jejudo and Baekdo Islands in Korean waters from 1971 to 2004. They are identified into three species within three families, which are newly recorded to Korean actiniarian fauna: Halcampella maxima Hertwig, 1888 within the tribe Athenaria, and also Aulactinia coccinea (Verrill, 1866) and Stichodactyla tapetum (Ehrenberg, 1834) within the tribe Thenaria. They are described in detail with figures and tables together with the distribution and size of cnidae. In preserved specimens, mature oocytes of H. maxima were observed in winter. Also oocytes and sperm sacs of S. tapetum were surveyed at separate individuals in summer. The unique feature of A. coccinea is a body wall with simple adhesive verrucae extended from margin to limbus in longitudinal rows. In the genus Stichodactyla, the smallest species, S. tapetum is distinguished from S. haddoni by short bulbous tentacles, less than 1.0 mm long, densely packed on the oral disc and also conical marginal ones, 1.5-2.0 mm long. As a result of this study, the Korean actiniarian fauna consists of four athenarian and 23 thenarian species in suborder Nynantheae
