White moss?

Can any one tell me what the white mossy stuff behind the crab is? Thanks

Here is another pic of them, I'm guessing they are sponges. Anyone else agree or know if it's something else

Unfortunately it's really hard to see in your pics what it is.

Yeah sorry I'm using the camera on my phone and its really small and the zoom is kinda bad. Thanks for looking though. Pretty sure they are just sponges I'll keep an eye on them
