CUTTLEFISH ARE ABLE TO RAPIDLY CHANGE THE COLOR OF THEIR SKIN TO MATCH THEIR SURROUNDINGS

Cuttlefish are able to rapidly change the color of their skin to match their surroundings and create chromatically complex patterns. Cuttlefish are also able to change the texture of their skin.

The skin contains bands of circular muscle which as they contract, push fluid up. These can be seen as little spikes, bumps, or flat blades. This can help with camouflage when the cuttlefish becomes texturally as well as chromatically similar to objects in its environment such as kelp or rocks.
