It is important to understand the interaction between deformable surface of creatures and its surrounding flow field. Hence we have carried out this study using four kinds of plate models having elasto-flexible surface to clarify the interaction. The deformation of the surface and the flow field around the model were observed using a laser light sheet visualization method. The visualization result showed that in the case of Model 1 the surface went up and down, but didn't generate any traveling wave, in the case of Model 2 nothing occurred on the surface, but in the case of Model 3 there were traveling waves generated on the surface. Then we made Model 4 equipped with a motor to generate traveling wave on the surface artificially. The visualization result on the Model 4 was that we could confirm traveling wave on the surface, and we investigated the characteristics of traveling waves.
