Octopuses are some of the most fascinating creatures in the ocean. These intelligent animals are known for their unique ability to change colors and blend in with their surroundings. But how do they do it? And why do they change colors? In this article, we’ll explore the science behind octopus color changes and what it means for these amazing creatures.

The Science of Octopus Color Changes

Octopuses have a complex system of pigment cells called chromatophores that allow them to change color rapidly. These cells contain pigments that can absorb and reflect different wavelengths of light, creating a range of colors. The octopus can control these cells using muscles, allowing it to change color and pattern in a matter of seconds.

But octopuses don’t just change color for fun. They use this ability to camouflage themselves from predators and prey, communicate with other octopuses, and even express their mood. For example, an octopus might turn bright red when it’s angry or stressed.

How Do Octopuses See?

In order to blend in with their surroundings, octopuses need to be able to see and analyze their environment. Octopuses have excellent vision, with eyes that are similar to human eyes in structure. However, their eyes are even more advanced in some ways. For example, octopuses can see in color, even though they are colorblind themselves. They can also detect polarized light, which helps them navigate in murky water.

The Benefits of Octopus Color Changes

Octopuses use their color-changing abilities to avoid predators and sneak up on prey. By blending in with their surroundings, they can avoid being seen by predators such as sharks, who might otherwise attack them. At the same time, they can use their camouflage to approach prey more easily, allowing them to catch their next meal.

But octopuses also use their color-changing abilities for communication. They might use bright colors to signal to a potential mate, or to intimidate a rival. They might also use color changes to indicate their mood, such as turning a darker color when they’re feeling stressed or threatened.

Can Octopuses Change Colors When They’re Out of Water?

Octopuses are known for their ability to change color underwater, but can they do the same thing when they’re out of water? The answer is yes, to some extent. However, octopuses can’t change color as effectively when they’re out of water. This is because their skin needs to be moist in order to change color using chromatophores.


Octopuses are truly amazing creatures, with a range of unique abilities that allow them to survive and thrive in the ocean. Their ability to change color is just one of the many ways they have adapted to their environment. Whether they’re using their color-changing abilities to avoid predators, communicate with other octopuses, or express their mood, octopuses are a fascinating and important part of the ocean ecosystem.
