  • 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.

  • The identified marine Tetractinomorpha consist of 6 species in 5 genera, 5 faimilesand 3 orders. Of those Two species, Poecillastra wondoensis and Jaspis wondoensis, are new to science and are described with detailed illustrations. Four species, Craniella ellipsoida. Discodermia tuberosa, Discodermia panoplia, and Stelletta validissima orthotriaena , are new to Korea and are remarked with illustrations.

  • 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.
