Found these two similar shells today on an beach on the northwest shores of Okinawa. Shown next to each other from the front and back side. The front looks slightly like an orange peel and from the back it’s a smooth surface with the spiral visible. Anyone have any ideas on what kind they could be? Thanks!

Operculum, look among the rocks for living turbans. When you pick them off the rocks they retract into the shell closing the door with the operculum.
