Abstract
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 해송류는 1과 2속 3종이 보고되어 있으며, 본 연구에서는 2003년부터 2005년까지 제주도에서 채집된 해송류로부터 3종인 빗자루해송 (Antipathes densa), 큰꽃해송 (A. grandiflora) 및 망해송 (A. dubia)이 새로이 한국 미기록종으로 보고된다. 이들은 주로 생태, 산호체의 분지양상, 폴립과 가시의 크기와 배열 및 자포형에 근거를 두고 기재를 하였다. 3종류의 자포형인 spirocysts, basitrichs, microbasic p-mastigophores를 지니고 있었으며, spirocysts와 basitrichs는 촉수에 분포하였고, microbasic p-mastigophores는 주로 격막사에 존재하였다.
