I came across this as a tiny guy and in two weeks Holy cripes did it embiggen! I searched all over the inter webs and it looks to be a worm but most pics come back to reefers asking what is it and then no answer. It is tube like, appears to have variegated segments, a feeding end with tentacles and moves like an inch worm. I believe this first pic is it small - that is a 2" marine pure cube for scale.
And this is it (maybe) a few weeks later, with a buddy.
And the video to show how it moves. Right after I shot this (just after lights started ramping up) it disappeared and have not seen it for a bit. (nightmare fuel below) It looked to be about 4-6" in length here and could stretch out quite a bit.
