Scorpions glow in ultraviolet light

Scorpions also glow under ultraviolet (UV) light. This otherworldly luminescence results from a substance in their exoskeleton called beta-carboline. When exposed to UV rays, they emit a bright blue-green light. Baby scorpions and recently molted ones exhibit this striking fluorescent trait. 

The exact purpose of scorpion bioluminescence remains debated among experts. Some researchers suggest that the glow may protect them from the harmful UV radiation in sunlight. Field observations have also led scientists to believe that fluorescence could play a part in hunting, luring, or disorienting prey. Finally, the glow might also be a signal or identifier among scorpions.

Scorpions perform a special mating dance

During mating season, male scorpions first track down a suitable female by following the enticing chemical cues she leaves behind. Upon finding a prospective partner, the male works to pique her interest by performing various actions, such as waving his pincers or tail.

Known as the promenade à deux  (or dance for two), the ritual begins when the male takes hold of the female's pincers and guides her through an intricate choreography. Together, they perform mesmerizing movements, swaying back and forth or side to side in perfect unison. 

This enthralling spectacle may last anywhere from mere minutes to several hours. Throughout the dance, the male diligently searches for the ideal surface to deposit his spermatophore, a sperm-filled capsule vital to their reproductive process. 

Once he finds the perfect spot, he leads the female to the spermatophore, which she carefully retrieves using her genital opening. This crucial moment in their dance signals the fertilization of her eggs.

Scorpions are edible

If you travel to some regions of the world, you might be surprised to know they eat scorpions as a delicacy. Once these creatures die, you can eat them safely because their venom becomes harmless and inert upon death. Adventurous eaters should enjoy these animals' unique flavor and texture without the risk of being stung.

In some communities, scorpions are a valuable source of protein. Adults and children in remote areas hunt them. Today, scorpions have started to pop up in crowded city food scenes. Urbanites can easily find these exotic arachnids at street food stalls and local markets; they are usually deep-fried, grilled, skewered, and candied.

While dangerous, scorpions can also heal

Scorpion venom has two sides: it can harm and heal. For example, researchers have found that some of its components can selectively target cancer cells, offering promising leads for developing innovative cancer therapies7. 

Moreover, the venom has demonstrated antimicrobial properties, opening avenues for new antibiotic discoveries. Some ingredients of scorpion venom can suppress the immune system. People with autoimmune diseases like multiple sclerosis and rheumatoid arthritis might benefit from this venom effect.
