What is this???

Does any one know what this is growing on my sps? They look like limpets but it’s actually part of the coral structure. Any ideas??

looks like a dead coral skeleton to me - anything can be growing on it?

The first photos are from the underside of that coral. Coral is very much alive.

My first thought was coral boring spionid worms but they typically don't look like that.

Any antenna poking out at all?

Ahh ok, that makes sense to me now.. If you see any antenna protruding from those burrows (or a spider-like thread hanging out) that might be coral boring spinobid worms.. but I doubt that, those burrows would be much wider..

Have you tried to put it under flow to see if anything falls off of it?

Also look at this area under a magnifying glass/microscope/zoomed camera, could be eggs.

I see those on wild pieces. something living in the coral. I use the tip of my bone cutters to crush it and the coral heals over it
