Help freaky worm ID


New member
The lights are off and I was watching a huge work looked like an earthworm or something . It's body looked segmented . It was white and grey colored segments. I shined the flashlight on it as it came out from under a rock and thing thing was huge stretching farther than my biggest finger and was almost as wide as my Pinky. I tried to grab it to put in a observation tank and it got soft and was extremely strong and tight and I even tried to pull as hard I could but it retracted all the way to below the rock into what looked like a tube anemone sack or something.

Anyone know? Sorry no pics next time I'll s at a flash shot can't believe I've never seen this before. Creeps me out . Looked like a freaky finger stretching across my sandbed .
