Can you please help ID this coral or polyp? I saw a number of them of the coast of St Lucia.

Looks like this to me: Sabellidae, or feather duster worm.

 

[Ukmc]

Here is another shot of it.

Yes some type of tube worm.
Feather duster worm could be possible

Looks like a feather duster worm to me. Ubiquitous throughout the Caribbean and the world.

...and you're looking at its ass.

 

[Ukmc]

Perfect, it is exactly what it is. And it is related to Christmas tree worm. Makes sense now.
Thank you, smart folks of the SB!
