Tubes on top of the sand

Anything in particular that might be making these tubes at the top of the sand out of sand?

Could be spaghetti worms? You’ll see their little tentacles fan out on top of the sand when they’re looking for food. They’re good clean up crew, in my opinion .

Interesting. I did some searching of spaghetti worm tubes and they look similar. Do they mostly reveal their “spaghetti” at night?
