In January and Feburary, 1995, fish and invertebrates inhabiting shallow-waters around Chichi-jima in the Ogasawara Islands were collected with box- and cylinder-type dredge on board fishing boat and with hand-net during SCUBA diving. And also, in December 1995 and January 1996, the intensive collections and observations were made by several researchers, within the financial and climatical restriction, at the sea off Ishigaki-jima and Iriomote-jima, the Yaeyama Group in the southern Ryukyu Islands. Systematic studies on many groups are now in progress, the preliminary reports indicating the presence of many species new to science and also new to Japanese fauna. Comparisons between the faunae of various groups from the Ogasawara and Ryukyu Islands suggest that many shallow-water species not only the shore-fishes indicated by Springer (1982 : Smiths.Contri.Zool., 367) but also the benthic invertebrates are distributed along the Philippine and Pacific Plates. This may be reasonable because the oceanic currents are generally induced along the island chains and ridges formed by the impact of Plates. On the other hand, the complex bottom conditions accompnied with trench and trough along the island chains might lead to the species diversity possibly interpreted with the vicariance theory.

1995年1月和2月，利用渔船上的箱式和圆筒式挖泥机以及水肺潜水时的手网收集了小笠原群岛父岛周围浅水区的鱼类和无脊椎动物。 1995年12月和1996年1月，多名研究人员在资金和气候限制下，在琉球群岛南部的八重山群石垣岛和西表岛海域进行了密集的采集和观测。对许多群体的系统研究正在进行中，初步报告表明存在许多科学上新的物种，对日本动物群来说也是新物种。小笠原岛和琉球群岛不同类群动物群之间的比较表明，许多浅水物种不仅有 Springer (1982：Smiths.Contri.Zool., 367) 指出的岸边鱼类，而且还分布有底栖无脊椎动物。菲律宾板块和太平洋板块。这可能是合理的，因为洋流通常是沿着板块撞击形成的岛链和山脊引起的。另一方面，岛链上伴随着海沟和海槽的复杂底部条件可能导致物种多样性可能用替代理论来解释。
