Topic: Dwarf cuttlefish

Dwarf cuttlefish, like octopus, are masters of camouflage. To camouflage the cuttlefish brain must solve a hard computational problem; the brain needs to process the visual environment, compute an appropriate pattern, and then orchestrate the expansion and contraction of hundreds of thousands of pigment filled sacs to generate it. How they accomplish this feat is unknown. Furthermore, cuttlefish do not camouflage by simply matching a substrate pixel by pixel; rather they produce an imperfect approximation of the substrate. Despite this they are able to evade detection by predator, prey, and ev
