One amazing snippet that is contradictory to human beings: octopuses are color-blind across their entire body (with their physical eyes as well as their "body" eyes) but they are excellent camouflage artists! How is that even possible. Don't you need to perceive color to be able to take it??

Hm, that is a good question. Evolutionarily, there is not necessarily any benefit for the octopus to being conscious of color, but there has to be some way in which its body, if only mechanically, "perceives" color and imitates it.
