Cephalopods are just one class among many organisms which have chromatophores, cells that have pigment and reflect light. Some species are able to change their coloring on demand in order to avoid predators. 

Roger Hanlon, a senior researcher at Marine Biological Laboratory in Massachusetts, was studying cephalopod camouflage when he came across an octopus who proved to be quite the master of disguise. Not only are cephalopods able to change color, but texture as well. 

In honor of Cephalopod Week, be sure to check out the video to learn more about these amazing animals. Can you spot the octopus before it changes color?
