There are two in the photo. The end of the thinner one was the width of only a few strands of hair. It was moving and probing the board at the time the photo was taken. The smaller one looked a little like a moving udon noodle. Photo is on a 2x6” board laid out by workmen in the area. A third one of these is partially visible in the second photo, bottom left, end stretched far out.

Looks like some segmented worm, but I can’t quite figure out what. It was living in a steam vent with boiling water.
