Scientists are starting to figure out how cuttlefish are able to instantly change the color of their skin even though they are colorblind. Turns out the fish have sensors – seemingly very much like retinas – that don’t connect to the animals’ brains. These sensors are linked directly to dye sacks. The cool thing is that there are many engineers who are picking up this research for practical applications such as color-changing paint and camouflage.
