odd hitchhiker - ID please?

Do a Google search on Peanut worms and Eunicid worms. That's about the best guess I have from that description.

Btw, bristleworms are beneficial scavengers.

It may be a peanut worm... Hard to see in the corner it is hidden. The pictures are so blurry I won't even bother posting them, all you can see is a blur as the worm hid.

But I am thinking that what I thought were bristle worms, may actually be Eunicid worm... What is the difference between the two?
