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.
How do cuttlefish know what color to change?
The skin of cuttlefish changes color rapidly using elastic pigment sacs called chromatophores, in order to evade predators.
Can all cuttlefish change color?
Cuttlefish and most other cephalopods — the class of animals that also includes squid and octopus — can change color to adapt to their surroundings in 300 milliseconds, or three-tenths of a second.
