![]() So they use their sensitivity to UV rays to determine if it's dim enough for them to crawl out and get to business. They lose some of what little water they have to evaporation. Scorpions do not like heat and bright light. However, the latest thinking, based on research at California State University, suggests another idea. And there is a school of thought that it doesn't serve any purpose at all. And some say that glow is a kind of sunscreen, which doesn't make much sense because scorpions are nocturnal. Some think they use it to dazzle their prey because many animals can detect ultraviolet light. One idea is that the glow might help scorpions find other scorpions, given the way they tend to blend in with their desert surroundings. Over the years scientists who consider such matters - arachnologists - have come up with a number of ideas. The real question is why? What's the purpose? Scorpions have certain proteins in their exoskeletons that react to ultraviolet rays and give them that creepy blue glow. Two questions here: How do scorpions glow under ultraviolet light, and why do they do it? The first one is pretty easy. I have never seen an explanation for why this is. Entire scorpion would effectively be one big eye.I often read that scorpions glow under a black light. Well, if this idea is right, it means that a scorpion’s glow could increase the surface area of its eyes by a thousand times. Those signals could even pass to the brain via clusters of nerves that are spread throughout the animal’s body. Some researchers believe that the scorpion’s entire body collects UV light from the environment and converts it into blue-green wavelengths. Scorpions could easily find such hiding spots by sensing light with their entire bodies so any object that casts shade upon their skin could reduce its glow and indicate a potential hiding place. You’ll often find them in the shade of a single twig or blade of grass. They like shelter and they’ll instinctively flee from light in an attempt to find it. In the open scorpions are vulnerable to owls, rodents and other predators. Scorpions amplify those faint signals by turning their entire bodies into light collectors. blue-green, this could explain why scorpion eyes are so exquisitely sensitive to the point where they can detect the faint glow of starlight against the background of the night sky. According to him scorpions glow to convert the dim UV light from the moon and the stars into the color that they see best i.e. Gaffin’s Theory about Scorpionsĭouglas Gaffin from the University of Oklahoma has a more intriguing idea. Glow could warn predators or help scorpions to recognize each other although neither possibility has been tested yet. Some proposed that scorpions could glow to lure their prey although it seems that insects actually avoid fluorescent scorpions. Researchers have suggested that it’s accidental the two chemicals responsible for the glow could be by-products of normal chemical reactions. ![]() Scorpions glow a vibrant blue-green, under the beam, lighting up like beacons against the darkness. Simply go into the desert in the middle of the night and switch on an ultraviolet (UV) light. Well! if you’re the type of person who looks for scorpions rather than runs screaming at the thought of them, you’re in luck, scorpions are easy to find. ![]()
