CUC flat worm?

[mww00ds]

So I've recently noticed this guy in the bottom on my tank fir the past couple weeks. Originally I thought it was a limpit but until I released it was the wrong shap and not ridge at all. I think it's a flat worm of some kind, but it never leaves the sand bed. It's always about 1-2 inches down and alway in about the same 3 inch radius. Is it possible to have a cuc flat worm or is this some other type of worm or nudi??? Thoughts or idea as to what this is?

Looks like a chiton.
What exactly is your definition of "cuc"?

It's a chiton. If you had a pic from the opposite side, you should be able to see the segmented plate shell (though the overlap of the foot looks like a match too).
