Looks like the diver was pasted into the picture!  ;o)

Actually, I think that its the Napolean Wrasse thats been pasted onto the picture. Verzasca Valley is in Switzerland, and probably fresh water and quite cold too ..... not the place you would expect to see a Napolean. I’m not an expert so please correct me if I’m wrong !!!!!

I’d just like to add that if it is a “cut and paste” it has been done very well, and makes an interesting picture.

How I said - it’s just an experiment :D Of course the Napoleon was added.
