Calabar Burrowing Boa (Calabaria reinhardtii) Care Sheet
The Calabar Burrowing Boa (Calabaria reinhardtii) is a small, secretive, fossorial snake native to western and central Africa.
Despite its common name, it is not a true boa in the same sense as Boa imperator or Boa constrictor. It belongs to the family Calabariidae and represents a highly specialised burrowing lineage.
Calabar Burrowing Boas are adapted to life beneath leaf litter, loose forest soil and ground debris. Their smooth cylindrical bodies, small heads and blunt tails allow them to move efficiently through substrate.
They are generally calm, slow-moving and reluctant to bite, but their secretive lifestyle means they are best appreciated as observation animals rather than frequently handled pets.
Successful husbandry centres on warm but not excessive temperatures, relatively high humidity, deep loose substrate, numerous ground-level retreats, good ventilation and appropriately sized whole-prey food.

Natural Distribution
Calabaria reinhardtii occurs across parts of western and central Africa.
Its range includes countries such as:
- Nigeria
- Cameroon
- Ghana
- Côte d’Ivoire
- Liberia
- Sierra Leone
- Guinea
- parts of central Africa
The species is associated mainly with humid forest environments.
Natural Habitat
Calabar Burrowing Boas inhabit environments including:
- tropical forest
- forest floor
- secondary woodland
- plantations
- areas with deep leaf litter
- loose humid soil
They spend much of their time beneath:
- leaf litter
- logs
- roots
- soil
- other ground debris
They may be encountered at the surface mainly during periods of activity, after rainfall or at night.
Appearance
Calabar Burrowing Boas have a distinctive, highly adapted body form.
They are generally:
- cylindrical
- smooth-scaled
- compact
- dark brown to reddish-brown
The body may display irregular pale or reddish markings.
The head is small and not strongly distinct from the neck.
The tail is short, rounded and blunt.
Head and Tail Mimicry
One of the most unusual features of the species is the resemblance between the head and tail.
When threatened, the snake may hide its head within its coils and expose the blunt tail.
This may help confuse predators by making it less obvious which end of the animal contains the vulnerable head.
The tail should not be mistaken for the head when handling.
Adult Size
Adults commonly reach approximately:
30–40"
Some individuals may be somewhat smaller or larger.
Females may become more robust than males.
Behaviour
Calabar Burrowing Boas are naturally secretive.
Typical behaviour includes:
- burrowing
- travelling beneath substrate
- hiding under cover
- emerging after dark
- slowly exploring the enclosure
Spending most daylight hours hidden is entirely normal.
A keeper should not repeatedly dig the snake up simply to confirm its presence.
Temperament
This species is generally regarded as very placid.
When frightened, individuals are more likely to:
- hide the head
- curl tightly
- push into substrate
- remain motionless
than to bite.
However, any snake is capable of defensive behaviour.
Handling
Calabar Burrowing Boas often tolerate brief handling well.
However, handling should not be excessive.
Repeatedly removing a fossorial snake from its substrate for recreational handling can create unnecessary stress.
Handling should be:
- gentle
- supportive
- relatively brief
- avoided immediately after feeding
Enclosure Size
For a typical adult:
36" × 18" × 18"
is a sensible minimum.
Larger accommodation can provide:
- deeper substrate
- more hides
- improved thermal gradients
- greater environmental complexity
Floor area and substrate depth are more important than excessive height.
Enclosure Security
The enclosure must be secure.
Calabar Burrowing Boas are strong burrowers and can exploit small gaps.
Check:
- doors
- lid edges
- cable openings
- ventilation gaps
- sliding-glass channels
Substrate
Deep, loose substrate is one of the most important husbandry requirements.
Suitable materials include:
- coco fibre
- coco husk
- pesticide-free topsoil
- cypress mulch
- forest substrate mixtures
- leaf litter
A depth of approximately:
4–6"
is strongly recommended.
Deeper sections are beneficial where space permits.
Substrate Moisture
The substrate should remain moderately moist but not waterlogged.
A useful approach is to maintain:
- slightly drier surface areas
- more humid deeper layers
This creates a natural moisture gradient.
Avoid permanently saturated substrate.
Leaf Litter
A generous layer of leaf litter is highly beneficial.
It provides:
- cover
- humidity retention
- naturalistic texture
- opportunities for concealment
- environmental enrichment
Only use pesticide-free leaves from safe sources.
Hides
Although the snake spends much of its time beneath substrate, conventional hides should still be provided.
Include:
- warm hide
- cool hide
- humid retreat
Useful options include:
- cork bark
- low hide boxes
- buried cork tubes
- leaf-litter mounds
Temperature Gradient
Provide moderate warmth.
Warm Area
Approximately:
27–29°C
Cool Area
Approximately:
23–25°C
The snake should always have access to cooler substrate.
Night Temperature
Night temperatures can fall moderately to approximately:
21–23°C
Avoid prolonged exposure to temperatures that are excessively cool.
Avoid Overheating
Calabar Burrowing Boas should not be maintained at extreme tropical temperatures.
Prolonged excessive heat can cause:
- dehydration
- stress
- surface-seeking behaviour
- feeding problems
Because the snake spends much of its time underground, substrate temperature should also be monitored.
Heating
Overhead heating is generally preferable.
Suitable options include:
- low-output halogen lamps
- deep heat projectors
- radiant heat panels
depending upon enclosure design.
The aim is to create a warm zone while allowing deeper and cooler retreat areas.
Thermostat
All primary heating equipment should be controlled by an appropriate thermostat.
Use independent digital thermometers to verify actual temperatures.
Humidity
Calabar Burrowing Boas naturally occupy humid environments.
A general humidity range around:
60–80%
is appropriate.
The substrate itself is particularly important because this species spends much of its time within it.
Humid Retreat
Provide a particularly humid microclimate using:
- damp sphagnum moss
- deeper moist substrate
- leaf litter
The snake should be able to choose between different moisture levels.
Ventilation
Good ventilation remains essential.
High humidity should not result in:
- stagnant air
- mould
- foul substrate
- bacterial growth
The objective is humid but fresh, well-ventilated conditions.
Misting
Light misting can be used to maintain humidity.
The enclosure should be allowed some partial drying between misting cycles.
Do not keep every surface continuously wet.
Water
Fresh drinking water must always be available.
Use a stable bowl large enough for comfortable drinking.
Some individuals may occasionally soak.
Replace contaminated water immediately.
Lighting
Provide a normal day/night cycle.
Approximately:
10–12 hours of daylight
is suitable.
Because this is a secretive fossorial species, intense lighting is unnecessary.
The enclosure should include extensive shaded areas.
UVB
Low-level UVB may be provided as part of naturalistic husbandry.
However, exposure will naturally be limited by burrowing behaviour.
If UVB is used:
- provide low intensity
- provide complete shade
- ensure the snake can remain underground
- avoid excessive heat
Diet in the Wild
Wild Calabar Burrowing Boas prey mainly upon small vertebrates encountered underground or at ground level.
Natural prey may include:
- small rodents
- nestling mammals
- shrews
- other small vertebrates
Their narrow head and burrowing behaviour suit them particularly well to entering rodent nests.
Captive Diet
Captive animals can generally be maintained on appropriately sized rodents.
Suitable foods include:
- mice
- young rats for larger individuals where appropriately sized
Frozen-thawed prey is generally preferred where accepted.
Prey Size
Offer moderate prey sizes.
The meal should create a modest swelling rather than heavily distending the snake.
Avoid oversized prey.
Juvenile Feeding
Juveniles can generally be offered prey approximately:
every 5–7 days
depending upon:
- prey size
- growth
- body condition
Adult Feeding
Adults can generally be fed approximately:
every 7–14 days
depending upon prey size and body condition.
Avoid excessive feeding.
Reluctant Feeders
Newly acquired or recently imported animals may refuse food due to:
- stress
- inappropriate temperature
- insufficient substrate
- lack of cover
- parasites
- incorrect prey presentation
Before attempting invasive feeding techniques, review husbandry thoroughly.
Feeding at Night
Because the species is predominantly nocturnal, food can be offered during the evening or after lights-out.
This may improve feeding responses in nervous individuals.
Feeding Tongs
Use feeding tongs.
Avoid hand-feeding.
After Feeding
Avoid unnecessary handling for approximately:
48 hours
after feeding.
Social Housing
Individual housing is recommended.
Separate housing makes it easier to monitor:
- feeding
- body condition
- faeces
- shedding
- health
Animals can be introduced deliberately for breeding.
Sexing
Reliable sexing may involve:
- tail characteristics
- probing by an experienced person
- veterinary imaging
- genetic testing where available
Incorrect probing can cause injury.
Breeding
Calabar Burrowing Boas have been bred successfully in captivity, although they are less commonly produced than many mainstream boas and pythons.
Only mature, healthy animals should be bred.
Reproduction
This species is oviparous.
Females lay eggs rather than giving birth to live young.
Egg Laying
Provide a secure, humid laying area containing:
- damp sphagnum moss
- moist soil-based substrate
- vermiculite
The laying medium should remain moist but not waterlogged.
Clutch Size
Clutches are generally relatively small.
Approximately:
2–6 eggs
may be produced, although variation occurs.
Incubation
Eggs require stable warm conditions and high humidity.
A temperature around:
27–29°C
is a reasonable general range.
Avoid overheating.
Eggs should not be rotated after laying.
Hatchlings
Hatchlings should receive:
- secure housing
- deep loose substrate
- multiple small hides
- fresh water
- appropriate humidity
- moderate temperatures
- minimal disturbance
Young animals should be allowed to burrow naturally.
Hatchling Feeding
Hatchlings may accept appropriately sized newborn rodents.
Some individuals may require patience.
Before changing prey types repeatedly, first ensure:
- temperature is correct
- substrate is deep enough
- the animal feels secure
- hydration is adequate
Quarantine
All newly acquired reptiles should undergo quarantine.
A minimum period of approximately:
90 days
is a sensible starting point.
Monitor:
- feeding
- weight
- faeces
- shedding
- respiration
- skin
- external parasites
Wild-Caught Animals
Historically, some Calabar Burrowing Boas in the trade have been wild-caught.
Wild-caught animals may arrive with:
- dehydration
- internal parasites
- external parasites
- chronic stress
- feeding problems
- skin damage
Captive-bred animals should be strongly preferred where available.
Parasite Screening
Animals of uncertain origin should be considered for veterinary faecal examination.
Treatment should be based on diagnosis rather than indiscriminate medication.
Shedding
Before shedding, the snake may:
- become dull
- develop cloudy eyes
- spend even more time hidden
- temporarily refuse food
Appropriate substrate humidity generally supports complete shedding.
Retained Shed
Repeated incomplete shedding should prompt review of:
- hydration
- humidity
- substrate moisture
- general health
Do not forcibly remove dry retained skin.
Signs of Good Health
A healthy Calabar Burrowing Boa should generally display:
- clear eyes outside shedding
- clean nostrils
- smooth intact scales
- appropriate body condition
- regular tongue flicking
- normal burrowing behaviour
- appropriate feeding
- complete sheds
Spending much of the day underground is normal.
Warning Signs
Seek veterinary advice for:
- unexplained weight loss
- persistent food refusal with declining condition
- repeated regurgitation
- wheezing
- open-mouth breathing
- nasal discharge
- skin lesions
- abnormal swelling
- persistent retained shed
- parasites
- neurological abnormalities
- severe lethargy
Common Husbandry Mistakes
Insufficient Substrate
Calabar Burrowing Boas are fossorial and need enough substrate to disappear beneath the surface.
Dry Enclosures
They require humid forest-floor conditions.
Permanently Wet Substrate
High humidity should not mean waterlogged housing.
Poor Ventilation
Humid enclosures still require good airflow.
Excessive Heat
Provide warmth without overheating the entire enclosure.
Constant Handling
This species is best allowed to express its natural burrowing behaviour.
Sparse Housing
Leaf litter, hides and deep substrate are important.
Poor Quarantine
Wild-caught animals can carry significant parasite burdens.
Captive-Bred Versus Wild-Caught
Captive-bred animals should be strongly preferred.
Advantages include:
- known origin
- established feeding
- reduced parasite risk
- reduced stress
- better adaptation to captivity
- reduced pressure on wild populations
Responsible Ownership
Before acquiring a Calabar Burrowing Boa, understand that a healthy animal may spend much of its life out of sight beneath substrate.
This is normal and should be encouraged.
Prospective keepers should be comfortable maintaining a species whose natural behaviour is largely hidden.
Suitability
Advantages
- manageable adult size
- usually calm
- generally reluctant to bite
- fascinating fossorial behaviour
- unusual evolutionary lineage
- modest space requirements
- suitable for naturalistic forest-floor enclosures
Considerations
- spends much of its time hidden
- deep substrate is essential
- requires relatively high humidity
- humidity must be balanced with ventilation
- captive-bred animals may be less readily available
- wild-caught animals may have parasite problems
- not ideal for keepers wanting a highly visible display animal
Summary
The Calabar Burrowing Boa (Calabaria reinhardtii) is a fascinating specialist snake whose husbandry should centre on its fossorial forest-floor lifestyle.
Provide:
- approximately 36" × 18" × 18" minimum for a typical adult
- 4–6" or more of loose substrate
- abundant leaf litter
- multiple secure hides
- a warm area around 27–29°C
- a cool area around 23–25°C
- moderate nighttime cooling
- approximately 60–80% humidity
- good ventilation
- fresh drinking water
- biologically appropriate whole prey
- minimal unnecessary handling
- strict quarantine
- preference for captive-bred animals
The most important point is simple: a Calabar Burrowing Boa should be allowed to burrow.
A shallow, exposed enclosure may make the snake easier to see, but it prevents one of the most fundamental behaviours for which this species is adapted.
When provided with deep substrate, appropriate humidity, secure retreats and stable temperatures, Calabaria reinhardtii can be a fascinating and rewarding specialist snake.
