Emperor Scorpion (Pandinus imperator)

Overview

The Emperor Scorpion (Pandinus imperator) is one of the largest scorpions in the world - adults reach 15-20 cm and weigh up to 30 g. A large, glossy-black African forest scorpion kept as a calm, hands-off display invertebrate. Famous for glowing blue-green under UV light. Docile with mild venom, but it is a sting-capable animal and not a pet to handle.

Natural History

Native to the hot, humid rainforests and savannas of West Africa (Ghana, Togo, Nigeria and nearby). Nocturnal and fossorial - spends the day in burrows and under cover, hunting at night. Maternal: females carry their pale young (scorplings) on their backs until the first moult. CITES Appendix II listed due to heavy collection from the wild, so captive-bred animals are strongly preferred.

Legal Status

Legal to keep in most of the United States and much of Europe, but CITES Appendix II means international trade is regulated - buy captive-bred from a reputable seller. Some cities and states restrict venomous or exotic invertebrates. Check local laws before considering.

Appearance

Adults 15-20 cm including the tail, occasionally larger. Glossy black body with large, robust pincers (pedipalps). Fluoresces bright blue-green under UV light.

Temperament & Handling

Calm and slow-moving, with relatively mild venom - a sting is often compared to a bee sting. But this is a hands-off pet: do not handle. Stings hurt, the large pincers can pinch, and any venom carries an allergy/anaphylaxis risk for some people. Treat it as a display animal you observe, not one you hold.

Use long forceps for maintenance and never put hands near the animal. Anyone with insect-sting allergies should be especially cautious - keep antihistamines on hand and seek medical care for any severe reaction.

Enclosure

Minimum: 40 × 30 × 30 cm for one adult; larger for multiples (though communal keeping is risky).

Provide:

• Deep coco fibre or soil substrate (10-15 cm) - keep moist so the scorpion can burrow.
• A secure hide (cork bark, half-log, or flat rock).
• A shallow water dish.
• No sharp edges; sturdy, low decor (scorpions are not strong climbers but will explore).
• Tight-fitting, secure lid.

Heating, Humidity, Lighting

• Temperature: 25-30°C (warm). Use an under-tank heat mat on one side, controlled by a thermostat.
• Humidity: 70-80%. Mist regularly and keep substrate damp.
• Lighting: No special daytime lighting needed (nocturnal). A handheld UV torch can be used briefly to view fluorescence - do not leave UV on the animal.

Diet

Carnivore: appropriately sized live insects - crickets, dubia roaches, locusts, mealworms (in moderation). Feed 2-4 insects every 5-7 days for an adult; adjust to body condition. Gut-load feeders and dust occasionally with calcium.

Provide fresh water in a shallow dish at all times. Remove uneaten live prey - crickets can stress or nibble a moulting scorpion.

Health & Lifespan

6-8 years (sometimes longer for females).

Common concerns:

• Dehydration / low humidity - sluggishness, trouble moulting.
• Failed moult (dysecdysis) - often from incorrect humidity; do not handle a freshly moulted scorpion (soft and vulnerable).
• Mycosis (fungal infection) - from stagnant, overly wet, poorly ventilated setups.
• Impaction or injury from falls or wrong-sized prey.

See an exotics vet who treats invertebrates if something seems wrong - invert veterinary care is specialised and not every clinic offers it.

Pros & Cons

Pros: striking large display invertebrate, calm and quiet, low daily effort, UV glow novelty, long-lived for an invert, mild venom. Cons: not for handling, sting and allergy risk, needs consistent heat and humidity, CITES-listed (buy captive-bred), feeds on live insects.
