  1. Octopuses Can See With Their Skin

    They’ve seen the light. Scientists have revealed that some species of the eight-legged cephalopods can sense changes in brightness with their skin using the same light-sensitive proteins found in eyes. This allows octopuses — among the smartest and most mobile of marine creatures — to camouflage themselves by using pigmented organs all over their bodies called chromatophores without engaging their brains. Their light sensors aren’t as keen as eyesight, but react like a more dramatic version of what human skin does when it tans.
