What is this?

I was looking at my tank and saw a bunch of these little white blobs on the live rock, could anyone tell me what it is?

It could be many things. I have some that looks the same and it was dead sponge. I've read that it could also be some type of mold. You can just scrape it off and take it out of the tank if you want. But it won't harm anything if you leave it in.

Possibly pineapple sponges
