Intertidal warts

I found these little sand bumps in odd patterns all over the intertidal zone on the beach. They're not buried rocks, and I couldn't find anything burrowed underneath them. Any Marine Biology types that would know what these are?

Aren't they the trapdoors of a razor shell or something other creature like that? They bury themselves in the sand when the tide is out and the come up into the open when the sea rolls back in?

Maybe, how small are they? I tried digging up a few, but couldn't find anything.

Well I for one think painloathing was actually on the moon and is just trying to be clever and trick us into thinking he was at a beach. Bloody moon men.

In Goa there were thousands of little crabs that would chase the edges of receding waves then disappear back into holes when the next wave came - maybe it's summat like that?

I suppose it is a razor shell. You could not find any because they are very sensitive for light and vibrations. They dig downwards very quickly.

these are blisters or domes of sand formed by many conflicts of wave movements within the water. They are directly linked to the butterfly effect. they occur in areas of low presure like gargae blown into alleyways in city streets.
