   Each octopus skin contains millions of chromatophores operated by muscles under direct neural control, enabling camouflage changes faster than any hormonal system could achieve.

   The mimic octopus can impersonate the shape and movement of other animals, such as lionfish and flatfish, adding behavioral mimicry to its camouflage repertoire.

   Octopus camouflage is controlled entirely by the nervous system, as octopuses are colorblind yet produce remarkably accurate color matches to their surroundings.

   Beneath their chromatophores, octopuses possess iridophores and papillae that allow them to mimic not just color but also the three-dimensional texture of rocky or coral surfaces.
