"Scorpion bodies are studded with eyes, sometimes as many as twelve — and scientists may have found one more. A scorpion’s entire exoskeleton may act as one giant light receptor, a full-body proto-eye that detects shadows cast by moonlight and starlight."
Douglas Gaffin of the University of Oklahoma and a team of scientists took scorpions, some which were blinded and some not and noticed something particularly odd; they all walked the around relatively the same.
"“Maybe they’re collecting stray UV light, maybe starlight, and pigments turn it to green, and that’s what their nervous system is picking up on,” Gaffin said.'How do they do this? I don’t know.'"
Crazy... so they might be using their exosekeletons as a sort of lunar GPS system. Very cool. Anyway, read the full story from the source below and go buy yourselves a scorpion and a blacklight.
