Coral reef invertebrate fauna of Sesoko Island and some other localities of Okinawa was studied in November, 1985, September, 1986 and in some other occasions.1. 15 spp. of demosponges were collected and their faunal analyses were attempted. (Hoshino)2. Life cycle and host preference of a bivalve associated hydroid were studied. This was found to be parthenogentic to some dgree. (Kubota)3. 12 spp. of hydroids including 2 new records from Japan were studied. (Yamada & Kubota)4. 143 spp. of hermatypic corals were reported from Sesoko and about equivalent number from Kudaka Island. Number of species decreased from 1980 to 86. (Sakai, Yamazato, Nishihira)5. 19 spp. of acoel flat worms including 10 new records from Japan were reported. (Yamasu & Okazaki)6. 17 specimens of benthic nematodes were studied as to their substrate preference. (Kito)7. 27 spp. and subspp. of serpulid polychaetes including 5 new records from Japan were recorded. (Imajima)8. Alpheid shrimp fauna with 5 new records from Japan was studied. (Nakasone & Yamaguchi)9 14 spp. of copepods parasitizing 14 spp. of ascidians were described. (Ooishi)10. Of 22 spp. of cheilostomatous bryozoans, 16 were new to Japan and all new to Okinawa. (Mawatari)11. 33 spp. fo echinoids belonging to 27 genera, 15 families and 8 orders were recorded. (Shigei)12. 14 spp. of ascidians belonging to 6 families were recorded. All except 3 spp. were new records from the area. (Nishikawa)

1985年11月、1986年9月和其他一些情况下，对Sesoko岛和冲绳其他一些地方的珊瑚礁无脊椎动物区系进行了研究。15种。收集了大量的蠕形虫，并对其进行了区系分析。(Hoshino)2.研究了一种双壳类伴生水母的生活史和寄主选择性。这被发现是某些Dgree的单性生殖。(久保田)3.12 spp.其中包括2个日本新记录种。(Yamada&Kubota)4.143 spp.据报道，Sesoko和Kudaka岛的珊瑚数量大致相同。物种数量从1980年减少到86种。(酒井、山里、西平)5.19种。其中包括10种日本新记录。(Yamasu&Okazaki)6.17个底栖线虫标本的底物选择性进行了研究。(Kito)7.27种。和亚种。发现锯齿类多毛类，其中日本新记录5种。(IMajima)8.研究了日本5个新记录种的对虾区系。(Nakasone&Yamaguchi)寄生于14个种的桡足类。描述了海鞘的种类。(Ooishi)22种中的10种在唇口苔藓动物中，有16种为日本新记录，冲绳均为新记录。(Mawatari)11.33种共记录到棘类8目15科27属。(石盖)12.14种。分属于6个科。除3种外，其余均为。都是该地区的新记录。(西川)
