In 2005, an unrecorded bryozoan, Bantariella sp., invading on black corals was observed at Munseom in Jejudo Island. An intensive study was performed in the portion of 180 m width and $10{\sim}30m$ deep of Hangae-chang at Munseom during the period from Jan. to Nov. 2006. The following two black corals, Antipathes japonica and A. lata are occurring in this area. To investigate the quantitative change of invasion rates, 26 colonies with initial invasion rate of 0%, 30%, 70% and 100% respectively were individually tagged at the beginning of this study. After that, the change of reinvasion rates was monitored in a timely manner with the pictures taken by underwater camera and ensile observation. These data were analyzed as to host species, depth and initial invasion rates. According to host species, the removal effect was higher in A. lata than A. japonica. The reinvasion rate of black corals showed a maximal effect at $20{\sim}30m$ deep, and the most successful removal effect appeared in the colonies of initial invasion rates of $30{\sim}70%$. Especially, the invasion of Bantariella sp. on black corals is related to seawater temperature in seasonal manner and this appearance was limitedly observed at Munseom. This study is to document the impact by bryozoan proposing removal methods and its proper time of removal. It could contribute to the conservation of black corals and furthermore help to predict the change of marine environments.

한국산 산호충류 중 각산호류의 계통분류학적 연구를 하기 이하여 1965년부터 1986년까지 남한의 삼면연안과 여러 도서지방을 조사하였으나, 황해 남부의 홍도, 남해 서부의 사수도, 거문도와 제주도 해역(9개 지역)의 총 12개 지역으로부터 51개체가 채집되어 이들을 동정분류하였다. 그 결과 1 과 2 속 3 종이 밝혀졌으며 이중 실해송(Cirripathes anguina)과 긴가지 해송(Antipathes lata)은 한국미기록종이었다.
