Is this a feather duster worm?

The title says it all.

I noticed this fella on the base of my wall hammer. Decided to try squirting it to see its reaction, but after i removed the screen to gain access, it was gone, i suspect retracted.

Yup

Hard to tell a feather duster worm will retract into its calcium shell.

 

[legrunt]

Yup

Thank you!

Yeah, that's what i thought, that's why i included the second picture showing it retracted.

Can you provide a pic with white light? You mentioned calcium shell which could be a Vermetid snail and if so should be removed/discarded

Looks like a feather duster.

Here's a pic with the whites.

No spiral shell. Fluffy head. Long tube...

Also there’s coco worms or some species like a feather duster except they use calcium or whatever to build their shell, those shells are typically white and then feather dusters are brown since they use mucus, sand, and organic material to build their tubes
