Whose discovery first revealed that scorpions glow under ultraviolet light?
Quick Answer
The fluorescent glow of scorpions was first noted by naturalists in the 19th century and later confirmed with ultraviolet light experiments.
The Full Story
Scorpions are famous for glowing blue-green under ultraviolet light, a trait that fascinated scientists once UV lamps became available. Early observers noticed the effect in the 1800s, but the chemistry and cause were studied more carefully in modern times. The glow comes from compounds in the scorpion’s cuticle, the outer layer of its exoskeleton. Researchers still debate the full biological purpose, though it may help scorpions detect light exposure or stay protected from too much sunlight. The discovery made scorpions one of the most visually striking arachnids in science education.
