Cuttlefish

Under the skin of the cuttlefish is arrayed a dense layer of elastic pigment sacs called chromatophores. They come mainly in yellow, red, black and brown. At a signal, the cells expand and flood the skin with the appropriate shade. That is how the cuttlefish takes on the colour of the rock it stands on and makes a perfect camouflage.

This system operates so effectively that the cuttlefish can also create a complex zebra-like striping.
