Does anyone know what this is

[ronwar]

It was on a rock underneath my polyps. It is round with what looks like little spines coming from it.
Any Ideas?
Thanks in advance

Thanks for the replies. I guess it could be a sponge, but the texture of the body is more fleshy than sponges I've seen. There is another small one about three inches from where I saw that one. My polyps started to disappear so I started to wonder. It hasn't moved since I've been monitoring them. I'll see...

I had something like that a while ago also. Last week when I was cleaning the aquarium I noticed what could have been a clam or some type of mollusk? If it is a spiny oyster is this ok?
