Good morning! Are the guys harmful? I have lots of worms I'm fascinated by. Never any this red. Also I have a creature you might know. I hope you do cause I don't. LOL. I'll take a pic. Thanks for the help.

This guy has a opening like a flower with 4 petals. There's an opening above the pic doesn't show. When closed you can't tell it's not just a rock. At night it moves enough water to move the sand. Reacts to light. Thanks.

Can’t make out what you have circled due to red lighting
Can you retake under white lights?

I'm afraid this is the best I'll get till dark. The spaghetti worm is in the way. See the divot in the sand from water discharge? I'll try to get a video of him closing and opening. Like those pods on the Alien movies.

Odd they were not known until a dip in fresh water.
