Did I find a bobbit worm?

I know there are beneficial hitchhikers, but I’m so creeped out by them. Can you guys help me ID these? I saw the antennae or whatever they are coming out of the hole in the rock. First I saw 2, and then there were 3. Could it be a bobbit worm? The other one is flat and whitish colored.

It is very difficult to tell with the blue lights. Try to get a pic in white light. but it looks to me like it may be a brittle star, which is a good thing.

Looks more like a brittle star to me.

I can’t see anything of detail in the blue. First is possibly brittle star but without white light pics impossible to tell.
