  • Two new marine sponges in the family Chalinidae, Haliclona (Haliclona) uljinensis n. sp. and Haliclona (Reniera) hongdoensis n. sp., are collected from Uljin and Hongdo Island, Korea during 2004-2007. H. (H.) uljinensis n. sp. is closely related to H. (H.) oculata in type of spicules. However, ectosomal skeleton of H. (H.) uljinensis n. sp. is reticulated and isodictyal reticulated type but H. (H.) oculata has not any dermal specialization in skeleton. The growth form of H. (H.) uljinensis n. sp. is thin encrusting with numerous cylindrical tubes on the surface but H. (H.) oculata is solid branch form. Haliclona (R.) hongdoensis n. sp. is closely related to H. (R.) aquaeductus in skeletal structure and growth form. However, oxeas of H. (R.) hongdoensis n. sp. are larger than H. (R.) aquaeductus's.

  • Two species of the family Chalinidae, Haliclona (Gellius) tubulensis n. sp. and Haliclona (Gellius) marismedi were collected from Hongdo Island and Gageodo Island, Korea during 2004-2007. H. (G.) tubulensis n. sp. is closely related to H. (G.) coreana in type of spicules and growth form. But it is different in size of toxas and oscules. Toxa of H. (G.) tubulensis n. sp. is one type and its oscules are tuberculated. The toxa of H. (G.) coreana is two types and lacks projections. The overall shape and spiculation of H. (G.) marismedi are nearly identical with specimens described by Pulitzer-Finali (1977).

  • A taxonomic study on marine sponges was conducted by SCUBA diving at Gageodo Island, Korea from August 1999 to July 2001. Among them, Haliclona (Gellius) coreana n. sp. turned out to be new to science. This new species seems to be close to H. (G.) arcoferus Vosmaer, 1885, based on the type of spicules. However, it is different in size of toxa and growth form. Toxa of the new species is half in length compared to H. (G.) arcoferus. The growth form is jar shaped in this new species, but flat in H. (G.) arcoferus.

  • Two marine species of family Callyspongiidae, Callyspongia mookriensis n. sp. and Siphonochalina truncata, were collected from Chujado Island and Jejudo Island, Korea during 2005-2007. Callyspongia mookriensis n. sp. is similar to Callyspongia flabelliformis Tanita, 1968 in type of spicule, habitat and growth form but differs in spicule and mesh size. The new species has longer oxea and broader mesh than Callyspongia flabelliformis's. The overall shape and skeleton of Siphonochalina truncata are nearly identical with specimens described by Lindgren (1897).

  • Two new marine sponges, Haliclona (Haliclona) tonggumiensis n. sp. and H. (Reniera) sinyeoensis n. sp., in the family Chalinidae were collected from Ulleungdo Island and Gageodo Island, Korea from 2007 to 2009. Haliclona (Haliclona) tonggumiensis n. sp. is similar to H. (H.) simulans (Johnston, 1842) in shape, but the former differs in its ectosomal skeleton structure and spicules' shape and size. The ectosomal skeleton of H. (H.) tonggumiensis n. sp. is absent, but that of H. (H.) simulans is very regularly arranged, and has tangential reticulation with oxea. The spicule shape of H. (H.) tonggumiensis n. sp. is slender, but that of H. (H.) simulans is short and cigar-shape. The new species have two sizes of oxea, but H. (H.) simulans has one size of oxea. Haliclona (Reniera) sinyeoensis n. sp. resembles H. (R.) tubifera (George and Wilson, 1919) in the growth form and choanosomal skeleton structure. However, the new species has two kinds of oxea in size, but H. (R.) tubifera has only one size.
