Pink waving legs!

Pink waving legs!
Description:

Wondered if this could be a burrowing brittle star or some kind of annelid. V. helpful suggestion from a marine biologist contact who says maybe it is a Cirratulid worm - possibly Cirratulus cirratus (Muller) or maybe Cirriformia tentaculata (Montagu). Could anyone confirm please?

yes...

....cirratulid worm - I would favour your Cirriformia tentaculata due to the masses of tentacles which on this cirratulid are bunched together. Without seeing the worm I would just go for cirratulidae - if you revise I will go with you.

Cirratulidae....

...as the filaments have blood vessels. If they were grooved they would belong to a terebellid. Usually there's no way to id species from just branchiae or feeding tentacles.
