Abstract

Some hydromedusae were collected from the coasts of Seogwipo(Jejudo Island), Hoenggando Island and Ilsanhaesuyokjang(Ulsan), Korea on July 11, 1985; July 23, 1990 and July 16, 1994. They were identified into Aequorea coerulescens (Brandt, 1838) of the order Leptomedusae, and Physalia physalis utriculus La Martiniere, 1829 of the Siphonophora, respectively. The unique morphological characteristics of A. coerulescens are smooth even surface of exumbrella, large mouth with 60 highly fringed oral lobes, shallow stomach, 120 simple radial canals and flat beret-shaped bell. In P. physalis utriculus its morphological characteristics are a triangular large pneumatophore with very low or rudimentary crest, a ribbon like long slender main tentacle, siphon-shaped gastrozooid with mouth, finger-shaped dactylozooid and branched gonozooid with gonophores. P. physalia. utriculus is the Pacific form and distinguished from the Atlantic form, P. p. physalis which has a much larger pneumatophore with high crest, numerous large main tentacles, and compact arrangement of basal and ventral cormidia. As a result of this work the Korean hydromedusan fauna consists of 15 species of five orders.

서귀포(제주도),, 횡간도 및 일산해수욕장(울산)에서 1985년 7월 11일, 1990년 7월 23일 1994 년 7월 16일에 채집된 히드라해파리류는 평면해파리(Aequorea coerulescens)와 작은부레관해파리(Physalia physalis utriculus)로 각각 동정되었다. 이들은 한국 미기록종으로 판명되어 재기재하여 보고한다. 평면해파리는 외산이 편평한 베레모 모양이고 큰 입을 가지며 60개의 주름진 구엽과 120개의 방사관을 가진다. 작은부레관해파리는 비교적 큰 부유기를 가지고 부유기의 아래에 섭식개충, 지상개충(=방어개충), 생식개충과 1개의 리본 모양의 큰 주촉수와 많은 작은 촉수를 가진다. 본 연구의 결과 지금까지 밝혀진 한국 해산 히드라해파리류는 5목 13과 15종이 된다.
