European Legless Lizard / Sheltopusik (Pseudopus apodus) Care Sheet
The European Legless Lizard, commonly known as the Sheltopusik or Pallas’s Glass Lizard (Pseudopus apodus), is a large terrestrial legless lizard distributed across parts of southeastern Europe and western and central Asia.
Despite its snake-like appearance, the Sheltopusik is not a snake. It belongs to the glass lizard family Anguidae and retains several obvious lizard characteristics, including movable eyelids, external ear openings and a body structure quite different from that of snakes.
Adults can exceed one metre in total length, although much of this consists of an exceptionally long tail. They are robust, active animals that require considerably more floor space than their relatively slender appearance might suggest.
Sheltopusiks naturally forage across open woodland, scrub, rocky slopes, grassland and cultivated areas. Their diet is varied and can include insects, snails, slugs and other small animal prey.
Successful captive husbandry centres on a large horizontal enclosure, substantial ground cover, diggable substrate, multiple secure hides, a warm basking area, appropriate UVB, seasonal temperature variation, fresh water and a varied whole-invertebrate and animal-based diet.

Not a Snake
One of the most important things to understand about the Sheltopusik is that it is:
a lizard without functional legs
rather than a snake.
How Can You Tell?
Unlike snakes, Sheltopusiks possess:
- Movable eyelids
- External ear openings
- A different skull structure
- A lateral body fold
- A very long tail
- Different locomotion
- Different feeding mechanics
Vestigial Limbs
Tiny remnants of the hind limbs may be visible close to the cloaca.
These are evolutionary remnants of the limbs possessed by their ancestors.
Natural Distribution
Pseudopus apodus has a broad distribution extending through parts of:
- The Balkans
- Greece
- Turkey
- The Caucasus
- The Middle East
- Central Asia
Exact distribution depends upon taxonomic treatment and locality.
Natural Habitat
Sheltopusiks occupy varied habitats including:
- Dry grassland
- Open woodland
- Scrub
- Rocky slopes
- Mediterranean-type habitat
- Agricultural margins
- Vegetated hillsides
They frequently use:
- Rocks
- Vegetation
- Burrows
- Leaf litter
for shelter.
Appearance
Adults possess:
- Long cylindrical bodies
- Very long tails
- Prominent lateral folds
- Strong heads
- Visible ear openings
- Movable eyelids
Adult Size
Adults commonly reach approximately:
90–120 cm total length
with some individuals exceeding this.
Much of That Length Is Tail
Unlike many snakes, a very large proportion of the Sheltopusik’s total length consists of tail.
This has important implications for handling.
Tail Autotomy
Like many other glass lizards, Sheltopusiks can shed part of the tail defensively.
This process is known as:
autotomy
Never Grab the Tail
Never restrain a Sheltopusik by its tail.
Tail loss is:
- Stressful
- Energetically expensive
- Avoidable in most captive situations
Tail Regrowth
Regrowth can occur but the replacement may differ from the original tail in:
- Shape
- Scale pattern
- Length
- Colour
Behaviour
Sheltopusiks are active terrestrial foragers.
Normal behaviour may include:
- Exploring
- Digging
- Moving beneath cover
- Basking
- Investigating scents
- Hunting
- Resting beneath hides
Activity Pattern
Activity varies with:
- Temperature
- Season
- Time of day
They may be most active during daylight under moderate conditions but shift activity during very hot weather.
Temperament
Captive-bred and well-established individuals can become relatively calm.
However, newly acquired animals may be:
- Nervous
- Defensive
- Fast
- Difficult to restrain
Defensive Behaviour
A frightened Sheltopusik may:
- Thrash
- Twist
- Attempt to flee
- Defecate
- Bite
- Attempt tail autotomy
Bite
The jaws are powerful enough to crush hard-bodied prey.
A defensive bite can therefore be painful.
Handling
Handling should be:
- Calm
- Infrequent
- Fully supportive
Support the body at several points.
Do not allow the long rear portion of the animal to hang unsupported.
Enclosure Orientation
The enclosure should prioritise:
floor space
rather than height.
Adult Enclosure Size
For one adult, approximately:
180 × 60 × 60 cm
should be considered a practical minimum.
Larger accommodation such as:
180–240 × 75–90 cm floor space
is strongly preferred where possible.
Why So Much Space?
These are active animals that naturally travel across substantial areas while foraging.
A long enclosure allows:
- Exercise
- Exploration
- Thermal gradients
- Multiple hides
- Feeding enrichment
Secure Construction
The enclosure must be securely closed.
Sheltopusiks are strong and capable of pushing into gaps.
Substrate
Provide a naturalistic, diggable substrate.
Suitable mixtures may include:
- Organic topsoil
- Washed play sand
- Coco fibre
- Leaf litter
- Fine bark in selected areas
Substrate Depth
Approximately:
10–20 cm
is useful.
Deeper sections can provide additional behavioural opportunities.
Why Diggable Substrate?
Digging and pushing beneath surface material allows:
- Natural behaviour
- Security
- Thermoregulation
- Humidity regulation
Substrate Moisture
Most substrate can remain relatively dry to slightly moist.
Provide at least one:
humid retreat
containing moisture-retentive substrate.
Hides
Provide several secure hides.
At minimum provide:
- Warm hide
- Cool hide
- Humid hide
Hide Size
A hide should allow the animal to make substantial body contact with its surroundings.
A huge open box may provide less security than a properly sized enclosed retreat.
Ground Cover
Additional cover can include:
- Cork bark
- Leaf litter
- Artificial vegetation
- Low plants
- Secure rocks
- Hollow logs
Heavy Furnishings
Any heavy rocks must be securely supported.
A digging animal should never be able to undermine a heavy object and become trapped beneath it.
Climbing
Although primarily terrestrial, Sheltopusiks may negotiate:
- Low rocks
- Logs
- Raised platforms
Low-level structural enrichment is beneficial.
Temperature Gradient
Provide a clear thermal gradient.
Basking Surface Temperature
Provide a localised basking surface around:
32–35°C
Warm Ambient Temperature
Maintain warmer daytime areas around:
24–28°C
Cool Area
Provide cooler areas around:
20–23°C
Night Temperature
Night temperatures may generally fall to approximately:
16–21°C
depending upon season.
Seasonal Temperatures
This species naturally experiences significant seasonal changes.
Captive conditions do not need to remain identical throughout the year.
Basking Temperature Is Not Ambient Temperature
A 34°C basking surface does not mean the entire enclosure should be maintained at 34°C.
The animal must be able to retreat into cooler areas.
Heating
Overhead heating is preferred.
Suitable sources include:
- Halogen flood lamps
- Appropriate incandescent basking lamps
Broad Heat
A broad basking zone is preferable to an extremely small intense hot spot.
Temperature Monitoring
Use:
Digital thermometers for ambient temperatures.
Use an:
Infrared thermometer for basking surfaces.
UVB
Appropriate UVB should be provided as standard husbandry.
Sheltopusiks naturally experience daylight and ultraviolet exposure while:
- Foraging
- Basking
- Moving through open vegetation
Target UVI
At the principal basking position, aim for approximately:
UVI 2.0–3.0
UV Gradient
Provide approximately:
Main basking area: UVI 2–3
Partially shaded area: UVI 1–2
Covered areas: below UVI 1
Inside hides: approaching UVI 0
What Does UVI Mean?
UVI means Ultraviolet Index.
For the keeper, it simply describes how much useful ultraviolet radiation reaches the animal at a particular position.
You are trying to create:
sunlight → partial shade → complete shade
rather than exposing the entire enclosure to the same UV level.
What UVB Lamp Do I Actually Need?
For most adult Sheltopusik enclosures, a good starting point is a:
quality linear T5 UVB tube
positioned above the basking side.
A moderate-output UVB tube, often within approximately the:
5–7% UVB class
can be appropriate in many typical installations.
Does That Mean Any 6% Lamp Will Work?
No.
The actual UV reaching the animal depends upon:
- Distance
- Mesh
- Reflector
- Lamp model
- Lamp age
- Basking platform height
What This Means in Practice
For somebody buying equipment for their first Sheltopusik:
Look for a:
good-quality linear T5 UVB system
rather than relying on a tiny compact UV bulb.
Place it over the same general area as the basking heat.
The animal should then be able to move from:
warm + bright + UVB → partial shade → covered ground → hide
Why Put UVB Near the Basking Area?
In nature, heat, visible light and ultraviolet radiation generally arrive together from the sun.
Combining them creates a clearer and more natural basking zone.
Mesh
Mesh can reduce UV output.
If the lamp sits above mesh, account for this when choosing:
- Lamp output
- Distance
- Basking height
Measuring UV
The most accurate method is an appropriate:
UV Index meter
Measure approximately at the height of the animal’s back while it is using the basking area.
If You Don’t Own a UV Meter
Many pet keepers will not initially own one.
Use:
- A reputable linear T5 system
- Manufacturer distance guidance
- Correct basking placement
- Plenty of shade
Do not simply purchase the strongest UVB lamp available.
Visible Lighting
Provide bright visible daytime lighting.
Additional daylight LED lighting can improve:
- Activity
- Circadian rhythm
- Enclosure visibility
- Natural behaviour
Photoperiod
During active periods, approximately:
11–13 hours of daylight
is appropriate.
Seasonal adjustment may be beneficial.
Night Lighting
The enclosure should become dark at night.
Do not use visible:
- Red
- Blue
- Purple
night lamps.
Humidity
General ambient humidity around:
40–60%
is suitable for many setups.
However, humidity should not be judged from one number alone.
Humid Retreat
Provide a humid hide containing suitable moist substrate.
This allows the animal to choose a higher-humidity microclimate.
Humidity and Ventilation
Do not create permanently wet, stagnant conditions.
Good ventilation remains important.
Water
Fresh clean water must be available at all times.
Provide a stable bowl large enough for easy drinking.
Hydration
Monitor hydration particularly during:
- Warm weather
- Shedding
- Seasonal transitions
Diet
Sheltopusiks are primarily:
carnivorous/insectivorous
and naturally consume a wide variety of prey.
Snails
Snails are particularly valuable prey.
The powerful jaws are well adapted to dealing with hard-bodied foods.
Safe Snail Sources
Use:
- Captive-cultured feeder snails
- Snails from a known safe pesticide-free source
Wild garden snails can carry:
- Parasites
- Pesticides
- Molluscicides
- Environmental contaminants
Other Suitable Invertebrates
Suitable foods can include:
- Locusts
- Roaches
- Crickets
- Earthworms from safe sources
- Snails
- Slugs from controlled safe cultures
- Silkworms
- Black soldier fly larvae
Whole Vertebrate Prey
Larger individuals may take occasional appropriately sized:
- Rodents
- Chicks
- Other small whole vertebrate prey
These should provide variety rather than dominate the diet.
Eggs
Egg can be offered occasionally as part of a varied diet.
Why Variety Matters
A varied diet provides:
- Different nutrient profiles
- Different textures
- Natural feeding behaviour
- Enrichment
Rodent-Heavy Diets
Do not turn a Sheltopusik into a rodent specialist simply because it will accept rodents.
Frequent calorie-dense vertebrate prey can contribute to excessive body condition.
Gut Loading
Feeder insects should be properly gut-loaded before feeding.
Calcium
Invertebrate prey should be appropriately supplemented with calcium.
Vitamin D3
When appropriate UVB is provided, dietary D3 should generally be used sparingly according to the overall supplementation programme.
Multivitamin
A suitable reptile multivitamin may be offered periodically.
Juvenile Feeding
Juveniles can generally be offered appropriately sized food:
daily or near-daily
depending upon meal size and growth.
Adult Feeding
Healthy adults can generally be offered food:
approximately 2–4 times per week
depending upon:
- Meal size
- Prey type
- Body condition
- Activity
- Season
Body Condition
Maintain a strong but not obese animal.
Do not equate:
heavier
with:
healthier
Feeding Enrichment
Encourage natural foraging by:
- Hiding prey beneath leaf litter
- Varying feeding locations
- Offering different prey types
- Allowing safe live invertebrate hunting
Social Housing
Individual housing is the safest general recommendation.
Multiple Animals
Cohabitation can create:
- Competition
- Stress
- Feeding inequality
- Reproductive pressure
Breeding introductions should be managed carefully.
Sexing
External sexing can be difficult, particularly in younger animals.
Sexual differences become more apparent in mature individuals but experienced assessment may be required.
Seasonal Cycling
Sheltopusiks originate from regions with pronounced seasons.
They may naturally show:
- Reduced appetite
- Reduced activity
- Increased hiding
- Winter dormancy
Brumation
Some captive animals undergo a period of winter cooling or brumation.
This may be particularly relevant for:
- Natural seasonal husbandry
- Breeding programmes
Do Not Assume Inactivity Is Always Brumation
Reduced activity can also indicate:
- Illness
- Incorrect temperatures
- Dehydration
- Parasites
- Nutritional problems
Planned Brumation
Only healthy animals in suitable body condition should undergo deliberate seasonal cooling.
Experienced veterinary guidance is sensible where there is uncertainty.
Breeding
Sheltopusiks are:
egg-laying
Seasonal Preparation
Successful breeding may be encouraged by natural seasonal cycling.
Courtship
Animals introduced for breeding should be monitored carefully.
Separate accommodation should always remain available.
Egg-Laying
Females require access to suitable nesting substrate.
Provide:
- Deep substrate
- Moisture
- Privacy
- Stable temperatures
Clutch Size
Females may produce approximately:
6–12 eggs
although clutch size varies.
Maternal Attendance
Females may remain with or guard eggs for a period.
Unnecessary disturbance should be avoided.
Female Nutrition
Breeding females require excellent:
- Calcium
- UVB
- Hydration
- Nutrition
Egg Retention
Seek veterinary advice for:
- Persistent straining
- Severe lethargy
- Abnormal swelling
- Weakness
- Repeated unsuccessful nesting behaviour
Incubation
Eggs may generally be incubated around:
25–28°C
under stable conditions.
Incubation Duration
Incubation may commonly last approximately:
45–60+ days
depending upon temperature and conditions.
Egg Handling
Avoid rotating eggs unnecessarily after laying.
Maintain appropriate humidity without saturating the incubation medium.
Hatchlings
Hatchlings require:
- Secure terrestrial accommodation
- Appropriate substrate
- Small hides
- Gentle basking heat
- UVB
- Fresh water
- Appropriately sized live prey
Hatchling Feeding
Suitable foods include:
- Small crickets
- Small roaches
- Small snails
- Earthworms of appropriate size
- Other suitable invertebrates
Hatchling UVB
Provide appropriate UVB from the beginning.
Growing animals have significant calcium requirements.
Quarantine
New animals should undergo quarantine.
Approximately:
90 days
is a sensible starting point.
Quarantine Monitoring
Monitor:
- Weight
- Appetite
- Faeces
- Hydration
- Skin
- Eyes
- Respiration
- Activity
Parasite Screening
Veterinary faecal screening is particularly valuable for:
- Wild-origin animals
- Imports
- Animals of uncertain history
Captive-Bred Preference
Captive-bred animals should be strongly preferred.
Advantages include:
- Known history
- Reduced parasite concerns
- Better adaptation to captivity
- Reduced collection pressure
Shedding
Sheltopusiks generally shed skin in sections rather than producing the complete shed commonly associated with snakes.
Appropriate:
- Hydration
- Humid retreats
- Rough surfaces
support normal shedding.
Retained Shed
Check particularly around:
- Tail
- Cloacal area
- Small vestigial limb structures
Metabolic Bone Disease
Inadequate:
- UVB
- Calcium
- Nutrition
can contribute to metabolic bone disease.
Possible signs include:
- Weakness
- Tremors
- Jaw abnormalities
- Skeletal deformity
- Difficulty moving
Respiratory Disease
Warning signs include:
- Wheezing
- Clicking
- Nasal discharge
- Persistent open-mouth breathing
- Severe lethargy
Mouth Health
Because these animals process hard prey, monitor for:
- Jaw swelling
- Mouth injury
- Abnormal saliva
- Difficulty eating
Signs of Good Health
A healthy Sheltopusik should generally display:
- Clear open eyes
- Alert behaviour
- Strong coordinated movement
- Regular basking
- Good feeding response
- Healthy skin
- Normal faeces
- Appropriate muscular body condition
Warning Signs
Seek veterinary advice for:
- Persistent food refusal outside expected seasonal changes
- Significant weight loss
- Weakness
- Tremors
- Jaw abnormalities
- Respiratory symptoms
- Severe lethargy
- Persistent diarrhoea
- Reproductive difficulty
Common Husbandry Mistakes
Treating It Like a Snake
A Sheltopusik is a lizard with different environmental and behavioural requirements.
Enclosure Too Short
Adults require substantial horizontal floor space.
Thin Substrate
Provide enough depth for digging and partial burrowing.
No Ground Cover
Use hides, cork, leaf litter and other visual cover.
Grabbing the Tail
Tail autotomy can occur.
No UVB
Appropriate UVB should be provided as part of modern husbandry.
Using Only a Small Compact UVB Bulb
A linear UVB system provides more useful coverage.
Buying UVB by Percentage Alone
Actual UVI depends upon distance and installation.
No Shade
The animal must be able to escape UV exposure.
Whole Enclosure Too Warm
Provide a localised basking area and cooler retreats.
No Humid Retreat
Even relatively dry setups should provide access to a humid microclimate.
Feeding Only Crickets
Dietary variety is important.
Feeding Mainly Rodents
Whole vertebrate prey should not dominate the diet.
Feeding Unsafe Wild Snails
Wild molluscs may carry parasites or contaminants.
Overfeeding
Maintain appropriate body condition.
Assuming Winter Inactivity Is Always Normal
Illness can resemble seasonal dormancy.
Conservation and Trade
The Sheltopusik is not currently listed under CITES.
However, local and national legislation can regulate:
- Collection
- Export
- Import
- Transport
- Keeping
- Sale
Wild collection may be restricted or prohibited within parts of its natural range.
Always obtain animals from lawful sources.

Summary
The Sheltopusik (Pseudopus apodus) is a large, long-lived legless lizard whose superficial resemblance to a snake hides very different anatomy and behaviour.
Successful husbandry centres on:
- Approximately 180 × 60 × 60 cm or larger adult accommodation
- Greater floor space strongly preferred
- Approximately 10–20 cm or deeper diggable substrate
- Multiple secure hides
- A humid retreat
- Extensive ground cover
- A basking surface around 32–35°C
- Warm ambient temperatures around 24–28°C
- Cooler areas around 20–23°C
- Night temperatures around 16–21°C depending upon season
- Appropriate seasonal variation
- A quality linear T5 UVB system
- Approximately UVI 2–3 at the main basking area
- Progressively lower UV exposure and complete shade
- Bright visible daytime lighting
- Constant fresh water
- A varied invertebrate-rich diet
- Safe feeder snails
- Occasional whole vertebrate prey rather than a rodent-dominated diet
- Proper gut loading
- Appropriate calcium and vitamin supplementation
- Individual housing as the safest default
- Careful handling with full body support
- Never restraining the animal by its tail
- Captive-bred animals strongly preferred
UVB in Simple Terms
If you’re choosing equipment and UVI 2–3 doesn’t mean anything to you yet, the practical advice is straightforward.
Look for a:
good-quality linear T5 UVB tube
rather than a tiny compact UVB bulb.
For many normal Sheltopusik enclosures, a moderate-output tube around the 5–7% UVB class can be an appropriate starting point when installed at the correct distance.
Place the UVB over the same general end as the basking lamp.
You are trying to create:
warm + bright + UVB
at the basking area, followed by:
partial shade → covered ground → completely shaded hide
The animal chooses how much UV exposure it wants.
The percentage printed on the tube does not tell you exactly how much UV reaches the animal. Distance, mesh and reflector design all change the result.
So rather than simply asking:
“Do I need a 6% or 12% bulb?”
the better question is:
“What UVI will this lamp provide at the animal’s actual basking position?”
Our target there is approximately:
UVI 2–3
If you don’t have a UV meter, use a reputable T5 system and follow the manufacturer’s current distance recommendations for that specific lamp.
