This is done rapidly and colorfully to match itself to the surrounding coral. IMG_6066But once you see it the color change is pretty obvious. I do admire the camouflage. Finally there is ink which can be squirted strategically to startle the pursuer. This actually worked upon me the first time I encountered this trick. This was the first octopus of the day and I got to see color changes. IMG_6074No he did not surprise me. And in return I took his picture and did not eat him.
