White spirals on my Hammer

[Jordan J]

I got this hammer frag a few weeks ago. Anyone have any idea what these are? There are more of them the last few days.

They look like little feather duster worm tubes to me... Nothing to worry about even if the worms were there, and these appear long abandoned.

I did just find a feather duster hitchhiker recently. That makes sense. Thank you.

Happy to help, and welcome to the forum! ;Woot

Most likely a feather duster. But if you don't see and feathery tops soon, it could be vermatid snails -- then you can just superglue the tops of the tubes to keep them from multiplying.
