I just saw a video of an octopus changing its colour to match the rocks near him. How is this information processed (I’m assuming that octopus saw the colour of the rock and then had its body change its colour)? Can they recognize and identify colours?
In: Biology
Octopi and such have photoreceptors in their chromatophores similar to those found in the cone cells in the eye, basically those cells have some limited ability to “see” the surrounding environment and are able to change color to march it, this information being transmitted via the nervous system when, for example, the octopis front facing side changes color to match what is in proximity to the rear
