Well, I got a new phone yesterday which has an unbelievable camera... and I happened to have a very social octopus last night - so we were able to get several clear photos of the spots.
When you are close to him, you can see the spots appear to be internal, almost sac-like. They are not external colorings.
Here are a few of the "better" pictures and you can see regardless of movement or color changes, the spots remain.
I also paid extra attention to arm size. When he is swimming with legs stretched behind, you can tell all his arms are the same size.
* On another note - still can't get him to eat fiddlers on a regular basis. He still prefers red legs & small snails. (and of course the magic stick that brings shrimp!)
