This was found on a night dive. It is translucent and slimy. As we grabbed for it I thought it would pull apart and so we stopped. I’d have liked to seen all of it. For a brief moment we saw the other end, the head. But there was no way to see it all at once. The book says fire worm. It doesn’t look fiery but that matches the picture in my book. Fire coral burns when you touch it with your skin. It’s yellow colored. Maybe this fire worm is the same. Did I say we touched it? Yes, but with gloves and the dive stick. Remember, do not touch anything! It will cause some adverse reaction that you will likely regret. Nothing! Nada!
