Armadillo Girdled Lizard / Armadillo Lizard — Care Sheet & Morphs

Husbandry requirements

Armadillo Girdled Lizard / Armadillo Lizard — origin: South Africa, western Cape: the semi-arid Succulent Karoo / Namaqualand region, with winter rainfall, on rocky outcrops and crevices. PROTECTED SPECIES: listed on CITES (Appendix II) and protected under South African law. Captive breeding is very rare (1 young/year): almost all specimens in the trade are WILD-CAUGHT, often illegally. Acquire only captive-bred animals with traceability and legal documentation..

Terrarium temperature gradient

Night min15 °C

Cool side22–26 °C

Warm side28–32 °C

Basking spot35–40 °C

Heliophilic species of hot rocky habitats: provide a true basking spot under a lamp and a strong thermal gradient. A night-time drop is beneficial (down to 12-15 °C possible). A seasonal winter cooling (shorter days, lowered temperatures for a few weeks) stimulates the physiology and reproduction.

Enclosure (adult)

120 × 50 × 50 cm

Desert / semi-arid terrarium with a horizontal orientation, fitted with a stack of stone slabs creating numerous crevices (saxicolous species).

Minimum dimensions for a small group; increase the floor area and the number of crevices according to the number of individuals. Stack stable stones/slate (wedged against the floor, never placed on loose substrate, to prevent any collapse) providing narrow gaps where the group takes shelter. Keeping is subject to regulation (CITES II).

Humidity

30–50 %

Generally dry, well-ventilated environment. Nonetheless provide a humid hide (moss/slightly moistened substrate in a crevice) and a light morning misting for hydration and shedding.

Substrate

Sandy-loam mix (sand and soil)Stacked stone slabs / slate forming crevicesFlat rocks

Draining mineral substrate reproducing the rocky soil of the Karoo. Most of the setup rests on the stacks of stones: it is the crevices, not the depth of substrate, that structure the terrarium.

UVB

Recommended

Essential. Full-sun heliophilic species: high-index UVB (tube/bulb of the 10-12% type, Ferguson zone 3-4), placed above the basking spot with a shaded retreat area. Replace the source every 6-12 months.

Water source

Always available

A small dish of fresh water renewed regularly; the animal also hydrates via its prey and the droplets from a light morning misting.

Origin

Cordylidae

South Africa, western Cape: the semi-arid Succulent Karoo / Namaqualand region, with winter rainfall, on rocky outcrops and crevices. PROTECTED SPECIES: listed on CITES (Appendix II) and protected under South African law. Captive breeding is very rare (1 young/year): almost all specimens in the trade are WILD-CAUGHT, often illegally. Acquire only captive-bred animals with traceability and legal documentation.

Feeding & health

Diet

Insectivore — Crickets, roaches (Blaptica dubia), small locusts, various larvae; termites are the staple food in the wild.

Varied prey of appropriate size, dusted with calcium (with D3 depending on UVB) and occasionally with vitamins. Feed regularly but without excess; reduce intake during the winter cooling.

Breeding

Viviparous

Extremely low reproductive rate: most often a single young per litter, once a year or even every two years. A seasonal cooling is generally needed to trigger the cycle. This low fecundity explains the scarcity of captive-bred specimens and the poaching pressure on wild populations.

Health watch points

Chronic stress and anorexia (especially when kept solitary or in wild-caught individuals)
Internal parasites (nematodes, protozoa) common in wild specimens, requiring a faecal examination
Metabolic bone disease (UVB and/or calcium deficiency)
Dehydration and renal disorders / gout linked to an unsuitable environment
Thermal burns (under the lamp) and shedding retention

Frequently asked questions

Answers to the most common questions about keeping the armadillo girdled lizard / armadillo lizard.

How big does the armadillo girdled lizard get, and what does it look like?▾

It's a small, stocky lizard measuring 15 to 21 cm long including the tail, entirely covered in large spiny scales that give it the look of a tiny armoured armadillo. This rigid armour and its spines are its first line of defence against predators.

What terrarium should be set up for this rock-dwelling species?▾

Provide a desert/semi-arid terrarium, horizontal in layout, at least 120 x 50 x 50 cm for a small group, enlarged according to the number of individuals. The setup relies mainly on a stack of stone or slate slabs, firmly wedged against the floor (never placed on loose substrate, which risks collapse), creating the narrow crevices where the group takes shelter.

What temperature and basking spot should be set up?▾

Unlike many terrarium species, this heliophilic lizard needs a genuine basking spot under a lamp, between 35 and 40°C, with a gradient running from 22-26°C on the cool side to 28-32°C on the warm side. At night a drop to as low as 15°C is well tolerated, and a seasonal winter cooldown of a few weeks is even beneficial for its physiology and reproduction.

Is UVB mandatory?▾

Yes, absolutely: this is a full-sun heliophilic species that needs high-output UVB (Ferguson zone 3-4), positioned above the basking spot, with a shaded area always available to retreat into. Replace the tube or bulb every 6 to 12 months, as its output declines over time.

What humidity level and substrate should be provided?▾

The overall atmosphere should stay dry (30 to 50%) and well ventilated, on a sandy-loam mineral substrate that reproduces the rocky soil of the Karoo. Reserve a slightly moistened hide within a crevice, however, and lightly mist in the morning for hydration and shedding; the animal also drinks from a small dish of fresh water that is renewed regularly.

What does this armoured lizard eat?▾

It's an insectivore fed on crickets, roaches, small locusts and various larvae - termites make up most of its diet in the wild. Dust prey with calcium (with D3 depending on UVB exposure), feed regularly without overdoing it, and cut back during the winter cooldown.

Can a single individual be kept alone?▾

No, that would be a mistake: this is a highly sociable species that naturally lives in family groups that can number 30 to 60 individuals sharing the same crevices. Kept alone, it becomes severely stressed and wastes away; it must be housed as a pair or in a small compatible group.

Why does this lizard bite its own tail?▾

This is its signature defence mechanism: when threatened, it grips its tail in its mouth to form a spine-covered ring that a predator cannot swallow, protecting its soft, vulnerable belly. This behaviour is exactly what earns it the nickname "armadillo lizard."

Can an armadillo girdled lizard be bought freely?▾

No, absolutely not. The species is protected under South African law and listed on CITES Appendix II, and captive breeding is so rare (usually a single young per year) that almost all specimens in trade still come from wild capture, often illegal. Only acquire a captive-bred animal with full traceability and legal documentation.

How long does it live, and is it a beginner species?▾

Its longevity is remarkable for a lizard this size: 20 to 25 years, sometimes more, with good care. It is nonetheless an advanced-level species, due to its strict legal requirements, its gregarious lifestyle that must be respected, and the precise care its rocky terrarium demands.

How does this lizard reproduce, and why is it so rare in captivity?▾

It's viviparous, but its reproductive rate is extremely low: usually a single young per litter, once a year or even every two years, generally triggered by a seasonal cooldown. This very limited fecundity explains both the scarcity of captive-bred specimens and the poaching pressure on wild populations.

What health problems should be watched for?▾

Chronic stress and anorexia mainly threaten individuals kept alone or recently caught in the wild, which often carry internal parasites requiring a faecal exam. A lack of UVB or calcium exposes them to metabolic bone disease, while an unsuitable environment can cause dehydration, kidney disorders or burns under the lamp.
