The first way that octopuses use camouflage is to change the way their skin looks and feels. Octopuses control muscles under their skin that can make it look smooth or bumpy! For example, if an octopus is near a bumpy plant, to better blend in it will change its skin to match the plant’s bumpiness.
The second way that octopuses use camouflage is by changing the way they move. For example, to camouflage itself as a rock, an octopus will not only fold its eight legs close to the body and change the way its skin looks, but it will also change the way it swims to mimic the way waves might push a rock through the ocean.
Finally, a unique way that octopuses use camouflage is by changing the color of their skin. Octopuses can control the color of their skin because they have special cells in their skin that are filled with different colors. These cells are usually yellow, red or brown, and are attached to small muscles that can change the size of the color cell. To change the color of their skin, octopuses will make the color cells bigger or smaller by stretching or relaxing their muscles. For example, let’s focus on cells with red pigment. If an octopus relaxes the muscles connected to its red color cells, these cells will become really small and we would not be able to see red on the octopus’ skin. However, if the octopus stretches the muscles connected to its red color cells, these cells will also stretch and get bigger so that we would be able to see lots of red on the octopus’ skin. So, by changing the sizes of all the different color cells, the octopus can very rapidly create complex patterns that allow it to better blend in with its surroundings. Thus, by changing its shape, behavior and color, the octopus has an array of different camouflage techniques that allow it to successfully hide from even the most the most observant animal or human.
