When changing colour, the process is simple. The impulse from the light entering the cuttlefish’s eye, goes to the brain, then directly to its chromatophores. These are pigment-containing and light-reflecting organelles inside cells.

This allows the cuttlefish to instantly change colour, without even realising it.

The cuttlefish ranks top when it comes to blending in.

Disguising itself as sand is a common trick used to evade dolphins and sea lions.

Cuttlefish are highly adaptive creatures. The intelligence required to mimic sea vegetation is extraordinary.

When their cover is blown, the emergency use of its jet-propulsion comes into play.

If the cuttlefish feels endangered, it will expel ink from its ink sacs. The cuttlefish creates a smoke screen to impair its predator's visibility.

The second response to a predator is to release ink with mucus, called pseudomorphs or "false bodies".

Predators have been observed mistakenly trying to attack the pseudomorphs as the cuttlefish makes its getaway.
