White sack like things that look like the have a cotton texture growing under the skeleton or core part of my brain and bubble coral would be a sponge right?
i think spiders lay eggs in sacks, I could be wrong, but they look like that.
i dont have a camera that will take a pic to where you could see it.
If I suspect it doing any harm I will look into further info...
but Im pretty sure it is a sponge.
