Octopus camouflage

The Octopus eye can see a really wide angle, which probably helps with matching the background. The skin is kind of like an LCD screen, it has these colored pores that can expand and contract so if it wants to look blue in one spot, it contracts the red and green pores and opens the blue pores, and it all works together to make the overall camouflage. I went diving in Bonaire and saw a octopus on the coral reef, the color change was amazing and  see was the texture changes to match the reef.
