HOW DO CUTTLEFISH CHANGE COLOR INSTANTLY?
Cuttlefish, also known as the chameleons of the sea, can camouflage themselves by changing their color and patterns in an instant.
According to a report in Science Times, the cuttlefish changes color using a particular cell under its skin called the chromatophore. The cuttlefish has sacs in its chromatophores that are full of colored pigment. The pouches are surrounded by tiny muscles that contract when the cuttlefish desires to camouflage itself.
The contraction causes the sacs and pigment therein to expand, changing the color of the cuttlefish instantly. It can change its color entirely and become invisible to human eyes.
The cuttlefish skin contains up to 20 million chromatophore pigment cells, which are all operated at will from the brain of the cuttlefish. Engineers hope to manufacture fashion clothes that change color as well as army uniforms inspired by the camouflaging abilities of the cuttlefish.
