What type of anemone is this?

[Silvansaria]

Anyone know what type of anemone this is??

I only see it from time to time and just managed to take a pic before it disappeared:

I want to say it is most likely a feather duster.

Looks like a feather duster to me. Not an anemone.

"Bispira" feather duster maybe??

I'll continue to image search it - thanks for the input...

It's a species of sabellid fanworm.
