Hello good people of R2R, I noticed this rather large tube worm under my rocks today. It appears to be in a calcareous tube, I would put it at 7mm across. It has two speckled-looking antenna that you can see in the picture, along with a bit of what I asume is its mouth. Its head is rather like the head of a snail. Unfortunately it is facing away from the glass so it is hard to get a good look at the guy. I did some googling but this isn't like anything I'm seeing across various ID articles, any ideas?
