| Outline of Final Research Achievements |
We tested the hypothesis that Shinkaia crosnieri recognizes homogenous individuals by sensing of light emitted from fluorescence substance including each shell. But, it was not demonstrated from a behavioral experiment. On the other hand, we found under laboratory conditions that S. crosnieri creates internal water stream using its appendages and increases metabolic activity of epibiotic bacterial community associated with its body and that S. crosnieri individuals perceive external water stream and aggregate in an area with strong water current. Thus, these results were strongly suggested that one of the factors affecting the colonization of S. crosnieri in natural environments is the external water stream.
