This shot was the last of a series of 4 taken on a night dive. I first passed by a piece of coral with a unusual shape on it. I turned around thinking 'that must be something alive' because it had a symetrical shape.
I got one shot of the shape on the coral and then it started to move across the algae and coral changing color and shape. First it was orange with white splotches, then white with orange spots, then it changed shape, standing up like a tepee, then slipped off changing to this solid orangish going to green color.
The octopus image is done justice up to 7 x 10.
