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.

This study suggests a navigation route for maritime tourism cruise sail yacht that sails off from Yeosu, and passes by Baekdo and Geomundo with their live island culture, to Kimnyeonghang of the Jeju islands. Recently, there are increasing number of accidents in proportion to vitalizing marine leisure. That's why it should be examined by region and sea when developing safe sea route considering characteristics of the sailing yacht. Thus, it is needed to introduce marine culture, hold international sailing yacht race and develop multi-functional sea port according to the case of Geomundo. Also additional analysis for navigation ruote patterns and density of the fairway is required. This information will improve safe sailing level of sailing yacht that will help the local tourism industry.

Ten new species of genus Sarcotragus (Demospongiae: Dictyoceratida: Irciniidae) are described from Geomundo Island and Jejudo Island, Korea. All new species of the Sarcotragus are distinguished from the other reported species of Sarcotragus by the skeletal structure, especially fasciculate primary fibres. The characters of genus Sarcotragus have cylindrical primary fascicles filled with wads of filaments or flattened fascicles. All of the primary fibres are not cored with foreign debris. Secondary fibres have slightly fasciculate branch or plastic-like web. They are all not cored with foreign debris. All skeletal fibres are very irregular. The surface is covered with loose or tight filamentous membrane.

Paranebalia longipes (Willemoes-Suhm, 1875) is cosmopolitan and has been usually found in the algal and sponge debris on the sandy mud substrates. This species can be clearly distinguished from other species of Paranebalia by the presence of serration on posterior margin of pleopods, the number of articles on antennule and antenna, and number of teeth on flange of antennule fourth article. The genus Paranebalia is new to Korea. In this paper, we provide detail descriptions of the diagnostic characteristics and illustrations of the P. longipes. Additionally, type locality and world distribution of the genus Paranebalia are provided.
