When I was taking a break beside a small tide pool (about 30 cm in length) in an intertidal area, a plychaete warm came out of a crack in the rock and extended itself toward an orange-striped sea anemone. It touched the excretory-substance-like material that was stuck on the lateral wall of the sea anemone. It then touched a white string coming out of the mouth of the sea anemone (probably the mesenterial filament). Soon after, the warm went back to the crack. I was watching the warm for several tens of minutes. The warm seemed to be checking orange-striped sea anemones in the tide pool one after another. (translated by Asoh)
