Small worm on tuxedo urchin

[Rthines]

Saw my tuxedo urchin on the glass today and noticed this small bristleworm linking guy underneath. I haven't found much online so I figured id make a post. Sorry in advance for the shaky video

I'm unable to view your video since I don't have snapchat. Are you able to take a picture? Are you able to take the urchin out and pull the 'worm' off?

I can try to get some more pictures if hes still on the glass, I dont want to try to rip him off the rocks if hes on them.
