What on earth is it

[PeterEde]

I found this a few nights ago and posted a photo last night.
Tonight I watched it move very slowly like snail slow. It definitely moves around the rock.
But here's another photo showing its length. It's close to 1inch long.
Is it some kind of nudi

Thanks for that. From what I can see of it it's a Chiton.
