![]() Compared with the two previously identified fluorescent compounds, the new molecule likely contributes more weakly to scorpion fluorescence, the scientists say. This finding suggests that the new molecule, which the researchers found in several additional scorpion species, could help guard against parasitic infections in these creatures. They purified the compound showing the most intense fluorescence and identified its structure, which was a phthalate ester previously shown to have antifungal and anti-parasitic properties in other organisms. To find out, the researchers extracted compounds from molted exoskeletons of the scorpion Liocheles australasiae, using chemical conditions different from those used in prior experiments. Masahiro Miyashita and colleagues wondered if there might be other fluorescent molecules with different chemical properties that were missed in previous studies. Until now, only two fluorescent compounds, β-carboline and 7-hydroxy-4-methylcoumarin, had been identified in scorpions' hard outer shell, or exoskeleton. Watch the video below to hear more details and see the neon creatures in action.More than 60 years ago, scientists first recognized scorpions' propensity to glow under UV light. It’s possible that, once a scorpion realizes it’s a bright night, it may decide to seek shelter for fear of being seen too easily by some predator. The light didn’t affect the nonfluorescent specimens’ behavior, whereas the glowing ones spent more time in the covered half of the container. He conducted an experiment to test this, too, which entailed putting fluorescent and nonfluorescent scorpions in half-covered containers and then exposing them to UV light. Kloock believes the most likely explanation is that scorpions use their fluorescence to detect light. Under a full moon, when the scorpions’ fluorescence was at maximum capacity, the glowing ones attracted fewer flies, suggesting that the glow may actually hurt their ability to ensnare a snack. To test this, Kloock devised an experiment in which he blocked fluorescence in some scorpions and compared the number of flies they attracted at night to that of glowing scorpions. Find invisible sources of odor (pet urine, vomit, feces, etc) WITHOUT sniffing your carpet, soiled areas in hotel rooms, invisible inks, fake money, or even Scorpions and other insects in dark corners. It’s also been suggested that it functions as a natural sunscreen, which would’ve been especially critical back before the Earth’s ozone layer existed.Īnother idea is that fluorescence helps scorpions entice prey. It’s powered by 4 AA Batteries, compact and totally portable, and you will find many other applications for this handy UV light too. One, as Nerdist reports, is simply that it’s a “relic trait”-some holdover from earlier on in scorpion evolution that no longer serves any purpose. Over the course of his research, Kloock has come up with several hypotheses to explain the phenomenon. And in the following YouTube video, Veritasium host Derek Muller explores some of them with Carl Kloock, a biology professor at California State University Bakersfield who’s devoted more than 10 years to solving the mystery. ![]() Like certain other glowing animals, it’s not exactly clear why scorpions have this talent, but scientists have theories. ![]() Most scorpion species are fluorescent, meaning they glow-in this case, a dazzling bluish green-when exposed to ultraviolet ( UV) light. Next time you go hunting for scorpions under cover of darkness, here’s a handy hack: Bring a black light.
