Coraline algae worm

I don't know how else to describe this thing. Wondering if anyone knows what it is. Same color as the coraline algae.

Not enough detail of the "critter" to tell but it could be a chiton or sea slug. It's not a worm though from what I can see.

Cheers

MAYBE a nudibranch ? Doesn't look flat enough

Thanks, Sorry the pic isn't the greatest but its pretty small. Looking at the pics from Steve I'll go with the chiton. Haven't seen it again but if I do I'll try to get some better closeups.
