About the Armadillo Lizard
The armadillo lizard (Ouroborus cataphractus, formerly Cordylus cataphractus) is a Cordylid lizard native to the Western Cape province of South Africa. Its defining characteristic is a body covered in large, spiky scales that resemble armor plating.
When threatened, it exhibits a unique defensive posture by curling its tail into its mouth to form a ring, wrapping its entire body with its scale-armored exterior. This behavior inspired its common name due to its resemblance to an armadillo.

CITES Regulations & Acquisition
The armadillo lizard is listed on CITES Appendix II, requiring an export permit from South Africa for international trade.
How to obtain in Japan:
- Legally imported individuals from abroad (with CITES certificate)
- Captive-bred (CB) individuals from domestic breeders
Important: Unauthorized trade of wild-caught individuals is illegal. Always verify the CITES certificate or confirm CB status before purchase. Domestic prices range from ¥50,000–¥200,000 per individual, and supply is limited.
Setting Up the Enclosure
Enclosure Size
Armadillo lizards are highly social and group housing (3–10 individuals) is recommended over solitary keeping. Group housing results in less stress and more natural behaviors.
| Number of Individuals | Recommended Enclosure Size |
|---|---|
| 1–2 | 60 × 45 cm or larger |
| 3–5 | 90 × 45 cm or larger |
| 6–10 | 120 × 60 cm or larger |
Substrate
Recreate their natural arid, rocky habitat:
- Desert substrate (fine gravel to sand) as primary bedding
- Flat rocks positioned for hiding spots and basking areas; provide multiple rocky crevices
- Crevices and hiding spots are essential (armadillo lizards naturally burrow into rock gaps)
Temperature Management
Armadillo lizards are diurnal and require basking for thermoregulation (ectothermic).
| Area | Temperature |
|---|---|
| Basking Spot (Hot Side) | 35–45°C |
| Cool Side | 22–28°C |
| Nighttime (Overall) | 15–20°C |
Seasonality: In the wild, South Africa experiences cooler winter months (June–August), during which activity decreases. To encourage breeding, implement winter cooling (10–15°C for 1–2 months).
UVB Lighting
Ultraviolet B (UVB) lighting is essential.
- Target UVI: 3–4 near the basking spot
- Use T5 HO fluorescent lamps (10.0–12% UVB) or high-output UVB LED panels
- Photoperiod: 12–14 hours/day (reduced to 10–12 hours in winter)
Humidity
Armadillo lizards inhabit arid environments:
- Target humidity: 30–50% (dry)
- Install a humid shelter in one corner (with moistened sponge) to assist with shedding
Feeding & Feeding Schedule
Primary Foods
In the wild, armadillo lizards feed primarily on termites. In captivity, offer the following insects:
| Food | Characteristics |
|---|---|
| Crickets (Two-spotted, European) | Readily available staple; dusting is essential |
| Dubia Roaches | Nutritious; less odorous than crickets |
| Mealworms | Use as supplementary food only; high fat content—avoid overfeeding |
| Dried Termites | Close to natural diet; available online |
| Isopods (Woodlice) | Natural diet; excellent digestibility |
Calcium Dusting (Essential)
Dust all insects with calcium powder before feeding:
- Calcium (without Vitamin D3): Dust at every feeding
- Calcium + D3: Dust 2× per month
- Multivitamin: 1–2× per month
With proper UVB lighting, calcium D3 synthesis occurs naturally, but supplemental dusting increases safety.
Feeding Frequency
- Adults: 2–3 times per week (amount they can consume)
- Juveniles & Subadults: Daily to every other day (growth phase)
Breeding
Armadillo lizards are ovoviviparous (live-bearing), a rare trait in lizards.
- Breeding Season: Spring (September–November: Southern Hemisphere) following winter cooling (5–8°C for 1–2 months)
- Gestation: 6–9 months
- Clutch Size: 1–2 offspring (very small)
- Neonates are fully independent and feed immediately after birth
CB individuals are rare domestically, but successful breeding yields valuable animals.
Care Notes & Common Issues
Feeding Refusal
- Newly acquired individuals often refuse food for 1–2 weeks (stress-induced)
- Increase hiding spots and maintain a quiet environment
- Live crickets often trigger feeding responses
Cryptosporidium Infection
Imported individuals may carry internal parasites, particularly cryptosporidium.
- Symptoms: Weight loss, chronic diarrhea
- Prevention: Fecal examination at a reptile veterinary clinic is essential for new acquisitions
- Treatment: Currently limited treatment options exist; prevention through proper sanitation is paramount
Shedding Issues
- Excessive dryness can cause incomplete shedding
- Provide a humid shelter to mitigate this problem
Summary
The armadillo lizard stands out among reptile enthusiasts due to its unique appearance, longevity, and rare group-housing behavior. While CITES regulations make acquisition challenging and costly, proper care supports decades of successful keeping. It is moderately advanced for beginners but highly rewarding for experienced reptile keepers. Always verify CITES documentation and acquire from reputable breeders or retailers.
