Just curious. How does a shroom-ricordia-polyp attach to a rock. Does the organism secrete some sort of addhesive from the base or a muscular contraction? I've noticed that when a shroom comes detached from its rock naturally, there is nothing left on the spot where it came from. If it is a muscular fucnction, then I would think that one could use a small electrical charge to detach a mushroom from it's rock. I don't even know if anyone has tried this. Just curious.
