Little white stringy things

[Streetlamp]

I spotted these hidden in a rock crevice last night. Any idea what they are.

Could they be micro brittle star arms? Look with a flashlight after the lights go off.

No I don't think so. They are all in the same place and don't move,

Could be feather duster.

I have those and will be interested to find out what they are. Mine look like pieces of white thread pasted to the rock.

Following. I have the exact same things first on my blastomussa skeleton, then on my rocks.

My guess is spaghetti sponge or sponge variant. Harmless if so.

I think it's a tube feather dusters worms. can you touch them, are the tubes hard and brittle, or soft? If they don't move are some worms probably in them, don't look like anything else to me. Or just zoom somehow on them, and usually check after lights off, but slowly introduce the torch over them.

Nothing to worry about.
