Emperor Scorpion
Pandinus imperator
On This Page▾
🌍 Overview
The emperor scorpion is one of the largest scorpion species in the world and the most widely kept scorpion as a pet. Native to the tropical rainforest and savanna of West Africa, they are surprisingly mild-mannered compared to many smaller species. Under UV light their exoskeleton fluoresces a vivid blue-green - a phenomenon related to compounds in the cuticle whose precise function is still debated. Their venom is relatively weak for their size.

📜 History
Carl Ludwig Koch described the species in 1842. Collection for the pet trade eventually drew in regulators, and it was placed on CITES Appendix II, a rare step for an arachnid and rarer still for a scorpion. The permits that came with the listing turned the trade into a matter of public record: Benin's quota for 2001 alone ran to 42,781 ranched specimens, and Togo was allotted 13,500 ranched plus 1,000 taken from the wild. Ranching, in which gravid females are collected and their young reared for export, has been the main legal supply route out of West Africa ever since.

🤓 Did You Know?
Emperor scorpions fluoresce a brilliant blue-green under UV/black light. Scientists aren't entirely sure why, but the compound responsible sits in the hyaline layer of their exoskeleton, and scorpions do this under natural UV from moonlight too, not just an artificial black light.
