Ninjas of the animal world

[Haggis Killer]

I think it's real. The color shift when it turns visible is a bit jarring, but heck, isn't Nature wonderful? The things that would be hardest to nail in a shot like this would be the motion, both of the octo and the ink release. That stuff's real, for certain. Taking the shot as a whole, I don't see any way to reverse-engineer the octo into the proper shape on just any happened-by-it rock from some piece of footage. To do it this well would take a ton of planning, and that isn't generally in the shot. It's just sorta mosey-along the ocean floor video footage and seeing something cool.

I buy it.
