  • Two species in the genus Stelletta, Stelletta crusta n. sp and Stelletta maxima Thiele, 1898 have been Collected from Geomundo Island. Stelletta crusta n. sp is similar to Stelletta tetrafurcata Hoshino, 1981 in the clade of the dichotriaenes which is trifurcate or multifurcate but both species differ in spicule size and composition. Stelletta maxima is first recorded in the Korean fauna.

  • Two sponges, Stelletta subtilis (Sollas, 1886) and Stryphnus sollasi n. sp., were collected from depth of 24-30 m at Jeju-do Island and Chuja-do Island by SCUBA diving from July 2003 to June 2010. The new species Stryphnus sollasi n. sp is similar with Stryphnus niger Sollas, 1886 in the composition of spicules, however they differ in colour and spicule size. This new species has smaller oxeas and larger oxyasters than those of S. niger. This new species has two size categories of oxyaster but S. niger has one size category of oxyaster. The colour of S. sollasi n. sp is white, but the latter puce black. Stelletta subtilis (Sollas, 1886) is first recorded in Korean fauna.

  • A new glycerol ether has been isolated from a marine sponge Stelletta sp. By bioactivity-guided fractionation. The structure was established on the basis of NMR and MS analyses. The compound was evaluated for cytotoxicity against a small panel of five human tumor cell lines and exhibited significant cytotoxicity.

  • Two new species of the genus Stelletta (Astrophorida: Ancorinidae), S. spinulosa n. sp. and S. calyx n. sp., are described from the waters around Gageodo Island (Sohuksando) and Ulleungdo Island, Korea. S. spinulosa n. sp. is similar to S. crassispicula (Sollas, 1886) in the feature of entire animal, but differs from it in the shape of orthotriaene and the form and size of oxyasters. S. calyx n. sp. resembles to S. crater Dendy, 1924 in the shape of sponge, but the new species has four size categories of oxyaster whereas S. carter has no oxyaster.

  • 1994년 7월부터 1995년 9월까지 거문도와 부근섬으로부터 잠수부에 의해서 채집된 해산 해면류를 동정, 분류한 결과 1강 7목 19과 26속 36종으로 밝혀졌다. 이중 4종 Stelletta japonica Lebwohl, 1914(왜별해면), Caminella velata Lebwohl, 1914(껍질가마해면), Stylohalina hirta Topsent, 1898(거친침상해면) 그리고 Esperiopsis rugosa Thiele, 1905(주름발톱해면)이 한국 미기록종으로 판명되었다.
