The large rock in this image is clear evidence that some of the rocks are home to extant lifeforms. It is uncertain if the creature burrowed into an existing rock, or if the rock started out as a shell and was then encrusted with 'rock building' creatures, similar to Coral? On the left side of this rock the aperture of the shell can be clearly seen, along with the columellar, and peristome lips.
