Can Octopuses camouflage themselves?
Unlike other species, octopuses don’t have a hard shell or sharp spines to protect themselves, so camouflage is their best bet for avoiding hungry predators. By using their chromatophores and changing the texture of their skin (yes, they can do that too!) octopuses can seamlessly blend into rocks, corals and sponges.
Is camouflage a biomimicry?
Camouflage is one of the first and most enduring exercises in biomimicry. Military camouflage was first applied in the first world war. In one early razzle-dazzle experiment, many ships in the British and American navies were painted in zebra-like, angular patterns.
Can Octopus see color?
The eyes of cephalopods like octopus, squid, and cuttlefish possess only one kind of photoreceptor, implying that they are colorblind, being able to see only in greyscale. Chromatic aberration is the differential bending of light of different wavelengths (colors). …

Using detailed measurements of spontaneous pain-associated behaviors and neural activity, Crook has identified three lines of evidence that all indicate octopuses are capable of feeling negative emotional states when confronted with pain.
