Never see this before!

This came on some live rock I got. I thought it was actually part of the rock untill it moved and I took a closer look. It almost does a slow pulsing. I thought it might be some sort of sponge at first but ive never seen a sponge move like this thing does. Sorry for the crappy iphone pic, if you guys need a better pic ill break out the hd cam.

there deff no crab there this thing is attached to the rock it doesnt move. Its just the orangey red part that is in question here.

Thanks rick! What kind of care is involved in having one of these?
