Cuttlefish change skin colour and texture in less than a second

Thousands of pigment cells controlled directly by nerves alter cuttlefish skin.

Cuttlefish possess tiny elastic pigment sacs called chromatophores connected to radial muscles under neural control. By expanding or contracting these sacs alongside reflective iridophores, cuttlefish project dynamic moving colour patterns and 3D skin textures for camouflage.
