What is this on my Green Star Polyps

[King Nine]

I was looking at my tank before going to bed and saw these puffy white things on my green star polyps. I don't know if they are there while they are open and I just can't see them or if they only come out at night. I circled a lot of them so you can tell what I'm talking about. I don't remember seeing them before tonight.

Kind of blurry, but definitely a sponge. A pineapple sponge I think...

They are good filter feeders as well. I have many of them in shady areas on the rock work.

Thanks to everyone for the input.

Your welcome. I was lucky that the pic came out that clear even though someone mentioned it was a little fuzzy. My camera does not take good closeups even in macro mode.
