  • 항종양성 물질의 탐색과 개발을 지향한 해양생물유래의 생물활성물질의 화학적 연구의 일환으로서 해조류(12종류), 해면동물(3종류), 강장동물(2종류). 극피동물(4종류), 연체동물(10종류) 및 원색동물(2종류)의 각 용매분획을 대상으로 brine shrimp bioassay에 의한 세포독성을 검색한 결과, 극피동물의 별불가사리 초산에틸액스(LC$_{50}$: 283$\mu\textrm{g}$/ml) 및 해삼 클로르포름엑스(LC$_{50}$: 274$\mu\textrm{g}$/ml) , 연채동물의 보말고동 부타놀액스(LC$_{50}$: 263$\mu\textrm{g}$/ml) 및 따게비의 물엑스(LC$_{50}$: 360$\mu\textrm{g}$/ml)에서 가장 강력한 세포독성이 관찰되었다. 그리고 생물별로 살펴본 세포독성빈도는 극피동물이 가장 유망한 것으로 생각되었다.로 생각되었다.

  • Two new species of the genus Psammocinia (Dictyoceratida, Irciniidae), P. bergquisti n. sp. and P. gageoensis n. sp., are described from Gageodo Island (Sohuksando Island), Korea. P. bergquisti n. sp. is characterized by the thumb like appearance and secondary fibre which makes a broad plate or secondary web while other known species in Psammocinia has many narrow and simple secondary fibres. P. gageoensis n. sp. is very similar to P. mosulpia Sim 1998 in shape, but primary fibre of the new species has more complex fascicles and it is difficult to see the detritus in the fibre. The primary fibre of this new species is cored with the smaller sand than that of P. mosulpia.

  • Two new marine sponges of family Tedaniidae, Tedania (Tedon iu) songakensis n. sp. and Tedania (Tedonia) sasuensis n. sp. were collected from Jeju Island and Chuja Island, Korea between 2004 and 2005. T. (T.) songakensis n. sp. is similar to T (T.) purpurescen Bergquist and Fromont, 1988 based on its type of spicules, but is distinguished from growth form and size of small onychaetes. The growth form of this species is massive, and is compared with thin encrusting of Tedania (T.) purpurescen. The onychaetes of the new species is twice as long as that of T. (T.) purpurescen. T. (T.) sasuensis n. sp. is closely related to T. (T.) connectens (Bronsted, 1924) in type of spicules. However, it is different in size of onychaetes and growth form. The large onychaetes of new species is larger than that of T (T.) connectens. The small onychaetes of new species is smaller than that of T. (T.) connectens. The growth form is massive in new species, but thick encrustins in T.(T.) connectens. And T. (T.) songakensis n. sp. is similar to T. (T.) sasuensis n. sp. in growth form. However, the former is widely different from the latter in shape, color and size of all spicules.

  • The sponge specimens, which were collected by scuba divers from Komundo Island during the years from 1994 to 1995, identified into 36 species in 26 genera of 19 families. Among them four species, Stelleta japonica Lebwohl, 1914, Caminella velata Lebwohl, 1914, Stylohalina hirta Topsent, 1898 and Esperiopsis rugosa Thiele, 1905 are newly recorded in Korean waters.

  • A taxonomic study of the marine sponges was conducted with the materials collected from Gageodo Island (Sohuksando), Korea from August 1999 to July 2001. The sponges were identified into 35 species, 23 genera, 16 families, six orders, two subclasses and a class. Among them, two of Polymastia murrayi Burton, 1959 and Clathria (Thalysias) spicata Gray, 1924, are newly recorded to Korean fauna, and Stylocordyla korenna n. sp. is new to science.
