A new marine sponge, Antho (Acarnia) seogwipoensis n. sp., of the family Microcionidae, was collected from Seogwipo-si, Jeju-do, Korea, about 100 m in depth using a gill net on 1969. The genus Antho Gray, 1867 including Demospongiae, Poecilosclerida, Microcionidae, is a large group of sponges. About 100 species in Antho were reported from worldwide. The genus Antho contains five subgenera: Antho, Acarnia, Isopenectya, Jia, and Plocamia. Among them, about 30 species in Acarnia were described in world sponge. A new sponge's body shape is branching, size up to 124 mm wide, 213 mm high, 3-8 mm thick in branch and 7-9 mm thick in stalk. Antho (Acarnia) seogwipoensis n. sp. is similar to A. (A.) novizelanicum Ridley and Duncan, 1881 based on their spicules type and skeletal structure, but differs in the spicules dimension and growth form. This new species is branched growth form and have three kinds of toxa.

A new species of genus Clathria (Microciona) (Demospongiae: Poecilosclerida: Microcionidae), Clathria (Microciona) sinyangensis n. sp. was collected from Intertidal zone by hand at Seopjikoji, Sinyang, Jejudo Island, Korea on 15 Oct. 2008. C. (M.) sinyangensis n. sp. is closely related to C. (M.) pennata Lambe, 1895 in their spicules, but thick subtylostyle of new species is smaller than that of C. (M.) pennata's and has three sizes of toxa. Also, the new species has no dermal membrane.

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.

A new marine sponge in the family Microcionidae, Ophlitaspongia yongjeongensis n. sp. is collected from Yongjeong-ri, Hyeongyeong-myeon, Muan-gun, Korea during 2005-2007. O. yongjeongensis n. sp. is closely related to O. reticulata in growth form (shape and color). However, the thick style and slender style of O. yongjeongensis n. sp. are larger than O. reticulata's (Bergquist and Fromont, 1988).

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.

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.

울릉도와 가거도에서 2001년 10월과 2000년 7월에 SCVBA 다이빙으로 채집된 해면동물을 동정$\cdot$분류한 결과 유령해면속 (Clathria)의 곰바위유령해면[Clathria (Clathria) gombawuiensis n. sp.]과 가거유령해면 [ Clathria ( C.) gageoensis n. sp.]이 신종으로 밝혀졌다. 곰바위유령해면은 Clathria (C.) conica와 골편의 구성에 있어서는 유사하지만 골편의 크기와 성장형태에 있어서 많은 차이가 있었으며, Clathria (C.) conica는 작은 toxa를 가지지 않는다. 가거유령 해면은 Clathria (C.) hexagonopora와 유사하지만 골편의 크기와 성장형태가 다르고, Clathria (C.) hexagonopora는 작은 toxa를 가지지 않는다.

1986년부터 1999년까지 진도, 구룡포, 제주도에서 채집된 해면동물을 동정·분류한 결과 이오폰해면과(lophonidae)에 가시끈적해면 (Myxichela spinulosa)과 유령해면과 (Microcionidae)에 유극침유령해면 [Ciathria (Clathria) acanthostyli] 2종이 한국미기록종로 밝혀졌다.
