Mysterious creature

Please can anyone help me identify this creature? not a tube worm I don't think. But has long tentacle like structures that it extends and can retract them extremely quickly.

I have these too, it's a chaetopterid/parchment worm. They are completely harmless.

Here's a video of mine does it look familiar?

So I was researching and I think it's a spionid worm

Yeah it could be but either way it’s still pretty harmless as long as their population doesn’t get out of hand

Spionids look very similar to Chaetopterids - in this case, yours is likely a Chaetopterid:

In this case, it's probably a Chaetopterid worm - they're very similar to Spionid worms, but they tend to prefer burrowing in the sand instead of in the rocks, and they reportedly tend to have longer palps.

That said, I say probably because to make a proper ID involves removing the worm from its tube and getting pics of the body out of the tube, which just isn't feasible.

Generally, these aren't a problem unless their numbers start getting out of hand.
