i got some clearer pictures tonight, so from the last thread here's what we know. Its not a bristle or peanut worm. It's NOT a starfish of any type. it is an unsegmented noctunal worm with a wierd ass head.
Thanks bang, i was hoping you would get a look at this one. You hit it on the nose (pun intended), a little research taught me that what is pictured is only the proboscis of the worm, the body is comfortably inside the rock.
