  • 1994년부터 2002년까지 거문도로부터 SCUBA로 채집된 해면동물을 동정$\cdot$분류한 결과 벽옥해면속 (Jaspis)의 1종이 신종으로 밝혀졌다. 본 신종은 원도 다성해면 (Poecilastra wondoensis)으로 대공을 제외하고 표면 전체를 완전히 덮혀 있어 2종의 해면동물이 마치 한 종처럼 보이는 것이 특징이다. 본 신종은 골편의 형태에 있어서는 원도벽옥해면 (J. wondoensis)과 유사하지만 주대골편의 길이가 더 길고 4-5개의 대공이 한 곳에 집중되어 있으며. 살아있을 때에 황금색을 띠는 점에서 차이가 있다. 큰성상체의 미소골편이 있다.

  • Six new species of two genera Dysidea and Pleraplysilla (Demospongiae: Dictyoceratida: Dysideidae) are described from Jejudo Island, Dokdo Island and Guryongpo, Korea. Among them, five new species of the genus Dysidea are compared with other reported species in fibres structure, cored detritus and fibres arrangement. Dysidea niveus n. sp. is characterized by thin collagenous plate-like fibres. Dysidea dokdoensis n. sp. is similar to D. geomunensis Kim et al., 2020 in skeletal structure, but differs in length of surface conules. Dysidea hydra n. sp. is similar to D. mureungensis Kim et al., 2020 at the surface, but differs in fibres cored with spicules. Dysidea sabulum n. sp. is similar to D. glavea Kim et al., 2020 in cored large sands in fibres, but differs in having numerous large sands cored in fibres throughout the sponge. Dysidea hirsuta n. sp. is unique, only surface fibres cored with large sands but not in choanosome. A new species of genus Pleraplysilla, P. flabellum n. sp. is compared with seven other reported species. This new species is not encrusting but has a thick flabellate shape.

  • Eight new species of two genera Dysidea and Euryspongia (Demospongiae: Dictyoceratida: Dysideidae) are described from Gageodo, Ulleungdo, Geomundo, and Jejudo Islands, Korea. Four new species of the genus Dysidea are differentiated by the fibre structure, cored detritus, and fibre arrangement. Dysidea mureungensis n. sp. is characterized by the honeycomb shape of surface and no distinction between primary and secondary fibres. Dysidea glavea n. sp. differs by large sands cored in fibres and that the membrane easily separates from fibres. Dysidea geomunensis n. sp. has fibres that are thinner than those of D. glavea n. sp.. Dysidea corallina n. sp. is characterized by folded fan shape and the arrangement of secondary fibres. Four new species of the genus Euryspongia are differentiated by the fibre structure, cored detritus, shape of sponge, and fibre arrangement. Euryspongia radicula n. sp. is very different from other species by having regularly arranged fibres. Euryspongia spina n. sp. has a fence-like skeletal structure. Bridged type secondary fibres are arranged near the surface and web types are at the base of fibres. Euryspongia flabellum n. sp. has a very unique wide, thin leaf-like shape. String-like primary fibres of E. linea n. sp. are very unique and cored with large sized sands.

  • Seven new species of two genera Scalarispongia and Smenospongia (Demospongiae: Dictyoceratida: Thorectidae) are described from Gageo Island and Jeju Island, Korea. Five new species of Scalarispongia are compared to nine reported species of the genus by the skeletal structure. Scalarispongia viridis n. sp. has regular ladder-like skeletal pattern arranged throughout the sponge body and has pseudo-tertiary fibres. Scalarispongia favus n. sp. is characterized by the honeycomb shape of the surface and is similar to Sc. flava in skeletal structure, but differs in sponge shape. Scalarispongia lenis n. sp. is similar to Sc. regularis in skeletal structure but has fibers that are smaller in size. Scalarispongia canus n. sp. has irregular skeletal structure in three dimensions and ladder-like which comes out of the surface and choanosome. Scalarispongia subjiensis n. sp. has pseudo-tertiary fibres and its regular ladder-like skeletal pattern occurs at the choanosome. Two new species of Smenospongia are distinguished from the other 19 reported species of the genus by the skeletal structure. Smenospongia aspera n. sp. is similar to Sm. coreana in sponge shape but new species has rarely secondary web and thin and thick bridged fibres at near surface. Smenospongia mureungensis n. sp. has very simple skeletal structure.

  • 1985년부터 1987년에 걸쳐 남한의 동·서·남해로부터 채집된 해면동물과 그 동안 미해결로 보류되어 있던 표본들을 조사한 결과 총 24종이 밝혀졌는데 이중에서 23종은 보통해면류 이었으며 6종이 한국미기록종이고, 1 종은 육방해면동물로서 신종임이 판명되어 Aphrocallistes jejuensis 라고 명명기재한다. 한국미기록종에 대하여는 특기와 도판을 첨가하였다.
