Introduction
The Emperor Scorpion (Pandinus imperator) is one of the largest and best-known scorpion species kept in captivity.
Its impressive size, powerful pedipalps and generally defensive rather than highly aggressive nature have made it popular with invertebrate keepers.
Despite its reputation as a relatively manageable scorpion, it should still be treated as a venomous animal rather than handled as a conventional pet.
Successful husbandry centres around:
- Deep, compactable substrate
- High substrate moisture
- Good ventilation
- Warm but not excessively hot conditions
- Secure dark retreats
- Fresh drinking water
- Appropriate live prey
- Minimal disturbance
- Safe enclosure maintenance
Natural Range
Pandinus imperator is native to West Africa.
Its range includes areas of countries such as:
- Ghana
- Togo
- Benin
- Côte d’Ivoire
- Guinea
- Liberia
- Sierra Leone
- Nigeria
It primarily occurs in humid forest and associated woodland and savannah habitats.
Natural Behaviour
Emperor Scorpions are strongly associated with burrows and concealed retreats.
They may shelter:
- Underground
- Beneath logs
- Beneath roots
- Under rocks
- Within natural cavities
Burrows provide protection from:
- Predators
- Light
- Heat
- Dehydration
Deep substrate is therefore a fundamental husbandry requirement rather than simply decoration.
Size
Adults commonly reach approximately:
15–20 cm (6–8 inches)
when measured from the front of the body to the end of the extended tail.
Females are often heavier-bodied than males.
Lifespan
A captive lifespan of approximately:
6–8 years
is commonly reported, although individual longevity can vary.
Growth is relatively slow compared with many smaller invertebrates.
Enclosure
Emperor Scorpions require a terrestrial enclosure prioritising:
Floor space and substrate depth.
For a single adult, an enclosure around:
45 × 30 × 30 cm
provides a useful practical starting point.
Larger accommodation can be used provided appropriate environmental conditions can be maintained.
Excessive height is unnecessary and can increase injury risk from falls.
Security
The enclosure must be escape-proof.
Check:
- Doors
- Lids
- Ventilation openings
- Cable holes
- Corners
- Any movable fittings
Although Emperor Scorpions cannot climb clean glass, they may climb textured backgrounds, silicone seams, cork and enclosure furnishings.
A secure lid or door system is essential.
Substrate
Deep substrate is one of the most important aspects of Emperor Scorpion husbandry.
Suitable materials can include mixtures of:
- Organic topsoil
- Coco fibre
- Appropriate peat-free soil
- Clay-containing soil
- Sphagnum moss
The substrate should:
- Hold moisture
- Compact sufficiently to support burrows
- Remain free from fertilisers and pesticides
Loose decorative bark chips alone are unsuitable for a species that naturally constructs burrows.
Substrate Depth
Provide at least approximately:
10–15 cm (4–6 inches)
of usable substrate.
Deeper substrate of:
15–20 cm or more
is preferable where enclosure design permits.
More depth allows the scorpion to construct more natural burrow systems and select different microclimates.
Substrate Moisture
The lower substrate layers should remain:
Moist but not waterlogged.
The entire enclosure does not need to be constantly saturated.
A useful setup allows variation between:
- Moist deeper substrate
- Humid retreats
- Slightly drier surface areas
This creates environmental choice.
Burrows
Emperor Scorpions should be allowed to dig.
Do not repeatedly destroy or collapse burrows simply to make the animal visible.
A scorpion spending considerable time underground is displaying normal behaviour.
Burrows can be encouraged by partially burying:
- Cork bark
- Curved bark
- Secure hides
to create starting points.
Heavy Decorations
Rocks, slate and other heavy objects must be positioned securely.
Place heavy structures directly on the enclosure base or otherwise secure them before adding deep substrate around them.
A scorpion digging underneath an unsupported heavy object could cause it to collapse.
Hides
Provide at least one secure dark retreat.
Suitable options include:
- Cork bark
- Curved bark
- Artificial caves
- Secure pieces of slate
- Partially buried hides
More than one retreat provides additional environmental choice.
Leaf Litter
A layer of natural leaf litter can provide:
- Cover
- Environmental complexity
- Moisture retention
- Naturalistic foraging areas
Ensure collected natural materials are safe and free from pesticides and contamination.
Temperature
A useful general temperature range is approximately:
24–28°C
during normal activity periods.
A modest thermal gradient allows the scorpion to select its preferred temperature.
Avoid maintaining the entire enclosure at excessively high temperatures.
Heating
In a suitably warm room, additional heating may not always be necessary.
Where supplemental heat is required, heat should be provided in a way that preserves the natural cooler/deeper substrate gradient.
Do not place a heat mat beneath the enclosure.
A burrowing scorpion naturally moves deeper to escape excessive surface heat. Heating the substrate from underneath reverses this gradient and can expose the animal to increasingly hot conditions as it digs downward.
If a heat mat is used, it should be attached externally to the side of the enclosure and controlled appropriately.
Ambient room heating is another option.
Thermostat
Any powered heat source capable of overheating the enclosure should be controlled with an appropriate thermostat.
Always verify actual temperatures using a reliable digital thermometer.
Do not rely solely upon:
- Heater wattage
- Thermostat settings
- How warm the enclosure feels
Night Temperature
A modest nighttime temperature reduction is acceptable.
The enclosure does not need to remain at one identical temperature 24 hours a day.
Avoid prolonged exposure to excessively cold conditions.
Humidity
Emperor Scorpions originate from humid environments, but husbandry should not revolve around chasing one exact hygrometer number.
The more important factors are:
- Moisture-retentive substrate
- Humid burrows
- Fresh water
- Appropriate ventilation
- Protection from dehydration
Relative humidity readings around:
70–85%
are commonly encountered in successful setups, but readings naturally vary throughout the enclosure and over time.
Moisture Management
Do not automatically mist the enclosure every day according to a fixed schedule.
Instead:
Monitor the substrate.
Add water when necessary to maintain appropriate moisture in the deeper layers.
Water can be added directly to portions of the substrate rather than repeatedly spraying only the surface.
The enclosure should be humid without becoming swamp-like.
Ventilation
High humidity does not mean poor airflow.
The enclosure requires appropriate ventilation to reduce:
- Stagnant conditions
- Excessive mould
- Persistent condensation
- Deterioration of substrate
The goal is:
Moist substrate with adequate ventilation.
Water
Fresh drinking water should always be available.
Provide a:
- Shallow
- Stable
- Easily accessible
water dish.
Clean and refill it regularly.
The enclosure should not rely solely on misting as a source of drinking water.
Lighting
Emperor Scorpions are primarily nocturnal.
They do not require bright specialist lighting.
A normal day/night cycle from ambient room lighting is generally sufficient.
Avoid placing the enclosure in:
Direct sunlight.
Sunlight through glass can rapidly overheat a terrarium.
UVB
UVB lighting is:
Not required
for routine Emperor Scorpion husbandry.
If lighting is used for plants or display purposes, ensure the scorpion has extensive dark retreats and that lighting does not significantly overheat or dry the enclosure.
UV / Black Lights
Scorpions fluoresce under ultraviolet light.
This can make UV torches useful for:
- Brief observation
- Locating escaped animals
- Checking an enclosure
However:
Continuous or prolonged intense UV illumination should not be used simply because the animal fluoresces.
Use UV observation sparingly.
Feeding
Emperor Scorpions are predatory invertebrates.
Suitable captive prey includes:
- Crickets
- Cockroaches
- Locusts
- Mealworms
- Superworms
- Other appropriately sized feeder invertebrates
Dietary variety is preferable to relying exclusively on one feeder species.
Prey Quality
Feeder insects should be:
- Healthy
- Appropriately sized
- Properly maintained
Well-fed feeder insects provide better nutrition than poorly maintained prey.
Avoid feeding wild-caught insects from areas where exposure to:
- Pesticides
- Herbicides
- Parasites
- Environmental contaminants
cannot be excluded.
Feeding Adults
Healthy adults generally do not require large amounts of food.
Offering appropriate prey approximately:
Every 7–14 days
provides a useful general starting point.
Feeding frequency should be adjusted according to:
- Body condition
- Prey size
- Temperature
- Activity
- Reproductive status
Adult scorpions may naturally refuse food for extended periods.
Feeding Juveniles
Growing juveniles generally feed more frequently than adults.
Appropriately sized prey can usually be offered:
Once or twice weekly
depending upon size and developmental stage.
Do not leave potentially dangerous live prey continuously in the enclosure.
Uneaten Prey
Remove uneaten prey if it is not consumed within a reasonable period.
This becomes particularly important when the scorpion is approaching a moult.
Crickets and other live prey can injure a vulnerable moulting scorpion.
Fasting
An Emperor Scorpion refusing food is not automatically ill.
Scorpions can fast for extended periods, particularly:
- Before moulting
- Following a large meal
- During environmental changes
- During reproductive cycles
Monitor body condition and behaviour rather than attempting to force feeding.
Moulting
Like all scorpions, Emperor Scorpions must shed their exoskeleton in order to grow.
Before moulting, a juvenile may:
- Stop feeding
- Become less active
- Remain underground
- Appear unusually swollen
- Seal itself inside a retreat
This period can last for some time.
Do not disturb a scorpion suspected of preparing to moult.
During Moulting
Moulting is a vulnerable process.
During a moult:
- Do not handle the animal
- Do not dig it out
- Remove potentially dangerous live prey
- Maintain appropriate moisture
- Avoid major enclosure disturbance
A scorpion that has deliberately sealed its burrow should generally be left alone.
After Moulting
Immediately after moulting, the new exoskeleton is soft.
The scorpion may appear:
- Pale
- Soft-bodied
- Vulnerable
Do not offer potentially dangerous live prey until the exoskeleton and mouthparts have hardened sufficiently.
This can take several days or longer depending upon the animal’s size.
Handling
Routine handling is:
Not recommended.
Even relatively calm Emperor Scorpions can:
- Pinch
- Sting
- Fall
- Become stressed
Handling provides no necessary welfare benefit to the animal.
Venom
Emperor Scorpions possess venom and are capable of stinging.
Their venom is generally considered of relatively low medical significance compared with dangerous scorpion species.
However:
Individual reactions vary.
A sting can cause:
- Pain
- Swelling
- Redness
- Local irritation
Allergic or more significant reactions are possible.
Do not describe a sting as guaranteed to be equivalent to a bee sting.
Treat the animal as venomous and avoid unnecessary exposure.
Pinching
The large pedipalps are powerful.
An Emperor Scorpion may defend itself using its claws rather than its sting.
A pinch can be painful and may break the skin.
Safe Maintenance
For routine enclosure work, use:
- Long forceps
- Catch cups
- Appropriate containers
- Other suitable tools
If the scorpion must be moved, encourage it gently into a secure container rather than picking it up by hand.
Never lift a scorpion by its tail.
Temperament
Emperor Scorpions are often described as docile.
However:
Temperament varies between individuals.
A defensive animal may:
- Raise its claws
- Adopt a threat posture
- Attempt to pinch
- Sting
Respect defensive behaviour rather than repeatedly provoking the animal.
Housing Multiple Scorpions
Emperor Scorpions have sometimes been maintained communally.
However:
Communal housing carries additional risk.
Possible problems include:
- Competition
- Injury
- Cannibalism
- Feeding disputes
- Stress
- Difficulty monitoring individuals
For general pet husbandry:
Individual housing is the safest recommendation.
Communal Housing
Experienced keepers attempting communal housing should provide:
- Substantially more space
- Deep substrate
- Numerous hides
- Multiple feeding opportunities
- Careful observation
Animals must be separated if aggression or deterioration in condition occurs.
Communal housing should never be presented as necessary for the species.
Sexing
Sexing mature Emperor Scorpions can involve examination of:
- Pectines
- Genital operculum
- Body proportions
Pectines are comb-like sensory structures on the underside of the animal.
Sexing can be difficult for inexperienced keepers.
Avoid unnecessary restraint simply to determine sex.
Breeding
Only mature, healthy and correctly identified animals should be deliberately bred.
Before breeding, ensure there is sufficient accommodation available for:
- Adults
- The female
- The eventual offspring
Pairing scorpions introduces a risk of aggression and should be carefully supervised.
Courtship
Scorpion courtship involves a characteristic behaviour known as the:
Promenade à deux.
The male grasps the female’s pedipalps and manoeuvres her while searching for a suitable surface on which to deposit a spermatophore.
The female is then positioned over it to complete sperm transfer.
Pairing should not be left entirely unmonitored.
Gestation
Emperor Scorpions are:
Viviparous.
Females give birth to live young rather than laying eggs.
Gestation is long and may last many months.
Around:
7–9 months
is commonly reported, although development time can vary substantially with environmental conditions and reproductive history.
Birth
A gravid female should be provided with:
- A secure enclosure
- Deep substrate
- Appropriate moisture
- Stable temperatures
- Minimal disturbance
Disturbance should be kept particularly low around the time of birth.
Scorplings
Newborn scorpions are commonly called:
Scorplings.
They are born pale and soft and climb onto their mother’s back shortly after birth.
They remain dependent upon her protection during their earliest stage.
Maternal Care
Do not remove newborn scorplings immediately from their mother.
They remain on her back until completing their first moult.
During this period:
- Minimise disturbance
- Maintain stable conditions
- Do not attempt unnecessary handling
- Ensure the female has access to fresh water
Females may become more defensive while caring for young.
First Moult & Dispersal
After their first moult, the young eventually leave the mother’s back and begin becoming independent.
At this stage, they can be moved into suitable juvenile accommodation.
Individual rearing makes it easier to monitor:
- Feeding
- Growth
- Moulting
- Health
Juvenile Housing
Young Emperor Scorpions require the same fundamental conditions as adults:
- Moist substrate
- Secure hides
- Warm temperatures
- Fresh water
- Appropriate ventilation
The enclosure must be secure enough to prevent tiny juveniles escaping.
Water dishes for very small scorplings must not present a drowning risk.
Health Monitoring
Regularly observe:
- Body condition
- Activity
- Feeding response
- Moulting
- Limb condition
- Enclosure moisture
Scorpions do not require routine physical handling for health checks.
Much useful information can be obtained through observation.
Dehydration
Possible concerns associated with inadequate moisture include:
- Abnormal inactivity
- Poor body condition
- Difficulty moulting
- A shrivelled appearance
Ensure:
- Fresh water is available
- Substrate moisture is appropriate
- Temperatures are not excessive
Moulting Problems
Difficulty moulting can be associated with inappropriate environmental conditions or underlying health problems.
Do not attempt to manually pull an exoskeleton from a moulting scorpion unless under expert direction.
Intervention can cause severe injury.
Injury
Scorpions can suffer injuries from:
- Falls
- Heavy decorations
- Aggressive tankmates
- Live prey
- Incorrect handling
Serious injuries or unexplained deterioration should be assessed with assistance from an appropriately experienced exotic/invertebrate veterinarian where available.
Cleaning
Spot-clean as necessary.
Remove:
- Prey remains
- Mouldy food
- Excess waste
- Dead feeder insects
Complete substrate replacement should not be performed unnecessarily frequently.
Established burrows are an important part of the animal’s environment.
Bioactive Housing
Emperor Scorpions can be maintained in appropriately designed bioactive enclosures.
Suitable systems may contain:
- Deep naturalistic substrate
- Leaf litter
- Springtails
- Appropriate isopods
- Live plants
Bioactive does not mean maintenance-free.
Continue monitoring:
- Moisture
- Ventilation
- Waste
- Water
- Animal health
CITES & Legal Considerations
Pandinus imperator is listed on:
CITES Appendix II.
International trade is therefore regulated.
Documentation requirements may apply to:
- Import
- Export
- Re-export
- Commercial trade
Requirements vary by jurisdiction.
Always verify current regulations applicable to your location and retain relevant documentation.
Responsible Acquisition
Where possible, choose:
Captive-bred Emperor Scorpions from reputable, traceable sources.
Correct identification is important because several large black scorpion species can appear superficially similar.
Avoid animals of uncertain or potentially illegal origin.
Summary
Emperor Scorpions are impressive, long-lived tropical invertebrates whose husbandry depends heavily upon providing an appropriate underground environment.
Successful care centres around:
- Secure terrestrial housing
- Deep compactable substrate
- Opportunities for natural burrowing
- Moist deeper substrate
- Good ventilation
- Moderate tropical warmth
- Fresh drinking water
- Secure dark retreats
- Appropriate live prey
- Safe heating
- Minimal disturbance
- Careful management during moulting
Important principles include:
Do not place heating underneath the enclosure.
A burrowing scorpion should be able to move deeper into cooler, more stable substrate.
Humidity should be created primarily through appropriate substrate moisture rather than constant indiscriminate misting.
Deep substrate is essential for natural burrowing behaviour.
UVB is not required.
Routine handling is unnecessary and should be avoided.
Emperor Scorpions are venomous even though their venom is generally considered relatively low in medical significance.
Individual housing is the safest general recommendation.
Moulting animals must be protected from disturbance and live prey.
Newborn scorplings should remain with their mother until after their first moult.
With deep substrate, appropriate warmth and moisture, secure retreats and suitable feeding, Pandinus imperator can be a fascinating species to maintain in captivity.
