Is this a Medusa worm?

[Thunder_reef]

Found 2 of these tonight? It appears to be filter feeding and pulling what it catches to its central mouth. Video at link.
Thanks for looking.

Might be. Medusa worms are sea cucumbers.

Looks like a filter feeding sea cucumber to me (I'm not sure if it's a medusa worm specifically or not, as that term is generally used for Apodid sea cucumbers which have no legs/feet).
