How quickly can a cuttlefish change colour?

Cuttlefish can change color in just seconds, often within a few milliseconds, thanks to specialized cells in their skin called chromatophores, which contain different pigments. They can also use iridophores and leucophores to create patterns and effects. This rapid color change serves various purposes, including communication, camouflage, and predator evasion. Their ability to adapt their appearance quickly makes them one of the most remarkable color-changing animals in the ocean.
