Refractive tentacles?

What is this? Help me!

How does it act? Does it wave in the current? Retract if bothered? I'd say it's some kind of filter-feeder, it's probably harmless.

Looks a bit like a barnacle. Can you get a shot of the base (where the filaments come out of)?

Possibly, may have to pull it out to do so

I wouldn't worry about it too much. It is likely totally harmless.

Those are the barnacles filter feeders. They trap food and will retract into the shell.

If they're not retracting back into the shell, they look like the Polychaete identified in this link as Flabelligeridae.

Yes that is exactly what it is! Thank you so much! They are so interesting to watch!
