Why do scorpions glow under black light? 🦂
Scorpions glow under black lights because of fluorescent chemicals found in their exoskeletons! These substances absorb invisible UV light and re-emit it as a glowing blue-green light visible to the human eye, creating one of nature’s coolest nighttime effects. ✨
Theories suggest this adaptation might be used as a UV light detection system, enabling the scorpion to find the best hiding spots and the darkest places, it could also help them find each other, confuse prey, some mix of the above, or could simply be a byproduct of the cuticle (outer covering of a scorpion's exoskeleton) formation process.
Want to see scorpions with your own eyes? Join us this Saturday, June 20, at our Desert Dwellers Cool Summer Night! The first 200 guests starting at 6:00 p.m. will receive a FREE blacklight flashlight.
