What camouflage does cuttlefish use?
The cuttlefish (Sepia officinalis) camouflages itself by contracting the muscles around tiny, coloured skin cells called chromatophores. The cells come in several colours and act as pixels across the cuttlefish’s body, changing their size to alter the pattern on the animal’s skin.
What do octopuses use to camouflage?
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.
Does octopus perform camouflage?
Self-protection. Octopuses are highly intelligent animals, masters of camouflage that have evolved an array of tricks over tens of millions of years to avoid or thwart would-be attackers. They can match the colors and even textures of their surroundings, allowing them to hide in plain sight.
What is octopus camouflage called?
chromatophores
What are chromatophores? Chromatophores are organs that are present in the skin of many cephalopods, such as squids, cuttlefish, and octopuses, which contain pigment sacs that become more visible as small radial muscles pull the sac open making the pigment expand under the skin.
How does a cuttlefish use these pigments to change color?
Cephalopods control camouflage by the direct action of their brain onto specialized skin cells called chromatophores, that act as biological color “pixels” on a soft skin display. Cuttlefish possess up to millions of chromatophores, each of which can be expanded and contracted to produce local changes in skin contrast.

Can octopi change color?
Octopuses have thousands of color-changing cells under their skin called chromatophores that can change colors almost instantly.
How do octopuses know what color to change to?
Each of these cells contains an elastic sac of pigmented granules surrounded by a ring of muscle, which relax or contract when commanded by nerves extending directly from the brain, making the colour inside more or less visible. Octopuses are thought to rely mainly on vision to bring about these colour changes.
How does an octopus change its color?
Just beneath their skin, octopuses have thousands of cells called chromatophores. Each of these cells has a tiny sac filled with either a red, orange, brown, yellow or black pigment and by stretching or squeezing these sacs, they can rapidly change the brightness of each of these colours.
What is it called when an octopus changes color?
This process, often used as a type of camouflage, is called physiological colour change or metachrosis. Cephalopods, such as the octopus, have complex chromatophore organs controlled by muscles to achieve this; whereas vertebrates such as chameleons generate a similar effect by cell signalling.
Does octopus change colour?
Squids, octopuses, and cuttlefishes are among the few animals in the world that can change the color of their skin in the blink of an eye.
