In the three aquatic animal communities, i.e. littoral fish communities in Lake Tanganyika, pelagic fish communities in Lake Biwa, and littoral invertebrate communities of cuttlefish and shrimp in Philippine Sea, the ratio of laterality in each species oscillates with a period of several years. With the methods such as stomach contents analysis, we have clarified that the laterality in each community is dynamically maintained by the frequency dependent selection through the interactions between predators and their prey.
