In fact, octopus can not only "change face", but also "transform". Octopus not only changes its body color and appearance with emotion, but also changes with time and environment.

For example, they will imitate the color, surface texture and shape of the surrounding algae or rocks, making them look like a mass of algae or a rock, and quickly blend into the passing or staying background, which is the most flexible protective color known in nature.

There is a special octopus in Indonesian waters, which can disguise itself as other marine life to avoid disaster in times of distress. This octopus is the only marine animal found so far, which can pretend to be other creatures. This octopus can imitate other creatures perfectly. For example, when it is attacked by a clown fish, it will roll eight wrists into one and pretend to be a sea snake to scare off the enemy. Or put away your wrist and imitate it as a fish full of poisonous glands to reduce the attacker's appetite and get away with it;

Then he stretched his wrist and dressed up as a lionfish with striped poisonous fins, which made the enemy daunting.
