A single Arabic cowry is moving through a narrow water way. You can see a yellowish siphon and a pair of tentacles. The cowry approaches a purple sea urchin, which is moving its spines. The cowry touches urchin spines and then quickly changes direction of movement. The cowry kept moving while avoiding the sea urchin that was blocking its way. (translated by Asoh)
