10 Surprising Emperor Scorpion Facts

10 Surprising Emperor Scorpion Facts

Big pincers, a raised tail, and a name like "emperor" make this one of the more intimidating-looking pets in the hobby. Almost none of that reputation holds up once you look at the actual animal. For care basics, see our full Emperor Scorpion care guide.

1. Their sting feels about like a bee sting. Despite the intimidating pincers, emperor scorpion venom is mild, most people compare a sting to a bee or wasp sting: sharp, localized pain and some swelling, rarely anything more serious.

2. They rely on brute force more than venom. Their oversized pincers do most of the work capturing and crushing prey, the sting is more of a backup than a primary weapon.

3. They glow under UV light. Like most scorpions, their exoskeleton fluoresces a vivid blue-green under ultraviolet or black light, a trait scientists still don't fully understand the purpose of, and it happens under natural UV moonlight too.

4. They're one of the largest scorpion species in the world. Adults can reach 6 to 8 inches long, making them one of the biggest and heaviest scorpions kept as pets.

5. Mothers carry their young on their backs. After giving live birth, baby emperor scorpions (called scorplings) climb onto the mother's back and ride there until their first molt, completely dependent on her for protection.

6. They're ambush predators that dig for a living. Emperor scorpions are fossorial, spending much of their time in burrows they dig themselves, emerging mostly at night to hunt.

7. They can live over a decade. With good care, emperor scorpions commonly live 6 to 8 years, and some have been documented living past 10, unusually long for an invertebrate this size.

8. Despite the pincers, they're actually one of the calmer scorpion species. Their combination of low venom potency and generally docile temperament is exactly why they're one of the most commonly kept pet scorpions.

9. They're native to the tropical rainforests of West Africa, where high humidity and warm, stable temperatures are part of daily life, which is why captive setups need to replicate both closely.

10. Their exoskeleton doesn't grow, so they have to shed it entirely to get bigger. Like all scorpions, they molt periodically throughout life, and a scorpion is at its most vulnerable in the hours right after shedding its old shell.

Scorpions aren't the only ones keeping that secret, either. Researchers only discovered in 2020 that platypus fur glows the same blue-green under UV light, and nobody is certain why in that case either.
