It’s like something out of The Amazing Spiderman: as if scorpions weren’t cool (or scary) enough, if you shine a black light on them at night, they glow bright green.
Why? Douglas Gaffin and his fellow scientists in Oklahoma did some experiments with blindfolding scorpions (yikes), then shining lights on them, and watching their responses. They showed that the scorpions reacted to UV light as though the whole rest of their body (the cuticle or outer shell) were detecting the light! You can check out a colorful poster of their findings, or if that’s too dense, read a news article summarizing it.
