Some marine sponges were collected from Jindo Island, Kuryongpo and Chejudo Island during the period from 1986 to 1999. Among the identified species, two species Myxichera spinuloso (Tanita, 1968) and Clathria (Clathria) acanthostyli (Hoshino, 1981) are new to the Korean fauna.

A study on marine sponges was conducted by SCUBA diving at Ulleungdo Island and Gageodo Island, Korea during the period from July 2000 to October 2001. Two species, Clathria (Clathria) gombawuiensis n. sp. and Clathria (C) gageoensis n. sp., are new to the fauna of sponges. Clathria (C) gombawuiensis n. sp. closely relates to Clathria (C) conica Levi, 1963 based on the type of spicules, but differs in size of spicules and growth form, Clathria (C) conica has not small toxa. Clathria (C) gageoensis n. sp. is similar to Clathria (C) hexagonopora Levi, 1963, but it differs in size of spicules and growth form, also Clathria (C) hexagonopora has not small toxa.

Two new marine sponges, Clathria (Clthria) jungtaedoensis n. sp. and Antho (Antho) hataedoensis n. sp. were collected in Taedo Island, Korea. C. (C.) jungtaedoensis n. sp. is similar to C. (C.) striata. The new species, however, has many small toxa and massive form. A. (A.) hataedoensis n. sp. is similar to A. (A.) inconstans from Gulf of Naples, Italy, but differs from the latter in the size of spicules. The toxa in the new species is about one third as long as A. (A.) inconstans's.

본인은 1984년 6월부터1985년 5월까지 서해연안(작약도, 대천, 안면도, 안흥)과 남해연안의 삼천포를 중심으로 한 부근섬(신수도, 늑도, 비진도, 충무) 및 거제도, 제주도 등지에서 채집된 재료 90여점과 그간 미해결로 보류되어있던 기존 표본들을 동정분류한 결과 26 종의 기록종과 3 종의 한국 미기록종(Spongia officienalis , S. zimmocca, Tedania Tublifera)이 밝혀졌다. 기록종 가운데 Esperiopsis uncigera 와 Hymeniacidon sinapium은 재검토되었다.

A new L-isoascorbic acid derivative epi-leptosphaerin (1) and two known compounds leptosphaerin (2), and verongamine (3) were isolated from sponges of the orders Verongida and Thorectidae. Compounds 1 and 2 are most likely of sponge-associated fungal origin. In the present study, isolated compounds were investigated for their inhibition of soluble epoxide hydrolase (sEH), which is considered a promising target for the management of pain, inflammation, and comorbidities associated with diabetes. Compound 3, verongamine, displayed weak inhibitory activity against sEH with an $IC_{50}$ value $51.5{\pm}1.0{\mu}M$.

A study on marine sponges was conducted with the materials collected by SCUBA diving in Hongdo and Gageodo Islands, Korea from September 2004 to July 2005. Clathria (Clathria) hongdoensis n. sp. and Clathria (Clathria) sohuksanensis n. sp. turned out to be new to the science. Clathria (Clathria) hongdoensis n. sp. closely seems to C. (C.) acanthstyli Hoshino (1981), based on their spicules type. However, they differ in the size of spicules and growth form. Clathria (Clathria) sohuksanensis n. sp. is similar to C. (C.) bicalthrata Hooper (1996), except for lacking small toxas.

Two new marine sponges, Clathria(Clthria) gimnyeoungenesis n. sp. and Clathria(Clthria) reticularis n. sp., were collected in Jejudo Island, Korea by fishing nets in September 1994. C.(C.) gimnyeoungenesis n. sp. is closely related to C.(C.) toxipraedita Topsent, 1913 based on spicule types, but are different in the size of spicules and growth forms. Especially, the thick styles and large toxas length of this species are half of C.(C.) toxipraedita. Growth form of the new species is branched but massive encrusting in C.(C.) toxipraedita. C.(C.) reticularis n. sp. is similar to C.(C.) compressa Schmidt, 1862 based on spicule types, but are different in the size of spicules. Especially, large toxas of this new species is twice as long as C.(C.) compressa and they have large isochelae, which are absent in the latter.

Two new marine sponges, Halichondria jangseungenesis n. sp. and H. nagokenesis n. sp., of the family Halichondriidae, were collected from Uljin-gun, Gyeongsangbuk-do, Korea by SCUBA diving during the period from Apr 2007 to Aug 2007. Based on their spicule composition and skeletal structure, H. jangseungenesis n. sp. appears to have a close similarity with H. panicea (Pallas, 1766); however, they differ in length of spicule. The spicule length of oxea of H. jangseungenesis n. sp. is shorter than that of H. panicea. Based on their spicule composition and growth form, H. nagokenesis n. sp. is quite similar to H. cylindrata Tanita and Hoshino, 1989; however, but they differ in length of spicule. The spicule length of oxea of H. nagokenesis n. sp. is longer than that of H. cylindrata.

Two new marine sponges in family Halichondriidae, Halichondria ulleungensis n. sp. and H. hongdoenesis n. sp. are collected from Ulleungdo Island and Hongdo Island, Korea by SCUBA diving during 2003-2004. H. ulleungensis n. sp. is similar to H. corrugata Diaz, Pomponi and van Soest, 1993 in the type of spicule, but it is different in growth form and choanosomal skeleton. The growth form is encrusting, with numerous erected cylindrical tube, comparing with massive-lobate of H. corrugata. The choanosomal skeleton is confused with loosely arranged oxea tract, comparing with densely tracts with many spicules of H. corrugata. H. hongdoenesis n. sp. is similar to H. surrubicunda Hoshino, 1981 in type of spicule and growth form, but this species has two kinds (thick and thin) of oxea.
