Weird looking worm(???)

[Daddy-o]

Just saw this thing in my tank during water change.nevet saw it before. About 5 inches was visible and looked to be more in the coral.

What is it and is it safe? This end appeared to be the head, but nothing looked like a head. "Legs" going down each side look feathery.

If you decide to remove it I would suggest against picking it up with your hands.
