Abstract

The joint faunal survey of Jindo Island, Korea was performed by the Korean Society of Systematic Zoology during June 29-July 1, 2004 in commemoration of the 20th anniversary. In this study, 20 echinoderm species of 13 families, ten orders in four classes such as one crinoid species, seven asteroid species of four families in three orders, five ophiuroid species of three families in two orders, four echinoid species of two families in one order, and three holothuroid species of three families in three orders collected from six localities (Bealpo, Chopyung, Supum, Hoedong, Seomang, and $34^{\circ}11'N\;and\;126^{\circ}21'E)$ were identified. Of these, one crinoid (Antedon serrata), two asteroids (Solaster dawsoni and Distolasterias nipon) and one pohiudoid (Astrodendrum sagaminum) are newly added to the echinoderm fauna of Jindo Island and one holothudoid (Pseudocnus sp.) is newly recorded in Korean waters. The total 31 species are presently listed with some brief remarks and their distribution patterns are discussed based on the composition of geographical distribution forms.

2004년 6월 29일부터 7월 1일까지 이루어진 한국동물분류학회 창립 20주년 기념 합동채집회에서 벌포와 초평, 수품, 회동, 서망, 북위 $34^{\circ}11'N$과 동경 $126^{\circ}21'E$ 등, 진도의 6개 지역에서 채집되어 동정된 극피동물은 4강 10목 13과 20종으로서 바다나리가 1목 1과 1종, 불가사리류가 3목 4과 7종. 거미불가사리 류가 2목 3과 5종, 성게류가 1목 2과 4종, 해삼류가 3목 3과 3종이었다. 이들 중 바다니리류 1종, 가시예쁜갯고사리 (Antedon serrata)와 불가사리류 2종, 도우손햇님불가사리 (Solaster dawsoni)와 일본불가사리 (Distolasterias nipon), 그리고 거미불가사리류 1종, 나무거미불가사리 (Astrodendrum sagaminum)는 진도에서 처음 기록되는 종이며 1종의 한국 미기록 해삼류 (Pseudocnus sp.)가 포함된다. 과거기록을 포함하여 총 31종의 종 목록을 작성하였으며, 분포형과 종 출현양상을 근거로 진도 해역의 극피동물상을 논하였다.
