1.Boulder shore community : We showed two species of Buccinidae snail had two feeding mode ; carrion-feeding and hunting other snail. Detailed distribution of two species were investigated. Community structures on the intertidal and subtidal area were clarified, and the effects of boulder size and construction on the community structure were clarified also. Vertical distribution patterns of relative five species of limpet snail were investigated in detail, and defference of vertical distribution pattern of these species were determined by vertical migration after settlement. Two-direction sex change of an intertidal sea cucumber was clarified through field cagingexperiment.2.Rocky shore community : Shell plates of dead barnacle were remained, and the space in the shell was utilized by small organisms. The small barnacle, Chthamalus challengeri were preferred by small mobile mollusks. At the other hand, the large barnacle, Tetraclita japonica was utilized several group of animals ; mollsuca, crustacea, polychaeta etc. Barnacle shell influenced the vertical distribution of some small organisms.3. Subtidal community : Shelter effect on gathering of a sea urchin was shown by field observations and laboratory experiments. Water depth effect on growth, reproduction and recruitment of some scleractinian coral species were investigated.

1.Boulder海岸群落：研究表明，两种钉螺有两种取食方式：食腐和捕食其他钉螺。对两个种的详细分布进行了调查。阐明了潮间带和潮下带的群落结构，以及巨石大小和结构对群落结构的影响。对近缘5种帽螺的垂直分布型进行了详细的调查，并通过定居后垂直迁徙的方式确定了这些种类垂直分布型的差异。通过野外圈养实验，明确了潮间带海参的双向性别变化。2.岩岸群落：保留死亡藤壶的壳板，壳内空间被小生物利用。小型藤壶Chthamalus challengeri是小型移动软体动物的最爱。另一方面，大型藤壶利用了软体动物、甲壳类、多毛类等多种动物，藤壶壳影响了一些小型生物的垂直分布。潮下群落：通过野外观察和实验室实验，显示了对海胆聚集的庇护作用。研究了水深对几种珊瑚生长、繁殖和补充的影响。
