hello
i just saw that there was a slender black arm, kind of banded arm, coming out of one of my rocks. it was moving about and seemed to be looking for something then something came out of the end of its arm similar to a feather duster. I know its not just one arm because when i picked up the rock i saw two more arms retracting back into the rock.
any ideas what it might be??
thanks
ill try to get a pic
