GABOON VIPER (Bitis gabonica) CARE SHEET
The Gaboon Viper (Bitis gabonica) is a large, exceptionally heavy-bodied venomous viper native to tropical forest and forest-edge habitats of sub-Saharan Africa.
Its extraordinary geometric pattern provides extremely effective camouflage amongst fallen leaves and forest-floor vegetation. Gaboon Vipers commonly remain motionless for extended periods, relying heavily upon camouflage rather than immediately fleeing from disturbance.
This apparent calmness must never be mistaken for safety or docility.
The Gaboon Viper is capable of delivering a medically serious and potentially fatal envenomation. It is a specialist species requiring secure purpose-designed accommodation, experienced venomous-reptile management, emergency planning and compliance with all legislation applicable in the keeper’s jurisdiction.
This species is not suitable for inexperienced reptile keepers.
Captive-bred animals of documented provenance should be strongly preferred.

IMPORTANT VENOMOUS SPECIES WARNING
The Gaboon Viper is a dangerously venomous snake.
A bite constitutes a medical emergency.
This care sheet provides husbandry information. It is not a venomous-snake handling or restraint manual.
Keeping this species requires considerably more than general reptile-keeping experience.
Before acquisition, a prospective keeper should have:
- Appropriate specialist experience
- Secure purpose-built accommodation
- Secondary containment
- Effective escape prevention
- Written emergency procedures
- Appropriate veterinary arrangements
- Knowledge of appropriate emergency medical facilities
- A plan for accidental escape
- A plan should the primary keeper become incapacitated
- Appropriate legal permissions where required
- A responsible person who knows what animals are present and what to do in an emergency
The animal should never be acquired before the accommodation, security systems and emergency planning are in place.
SPECIES OVERVIEW
Gaboon Vipers are terrestrial ambush predators strongly associated with the forest floor.
Their natural environment commonly includes:
- Tropical forest
- Humid woodland
- Forest margins
- Dense vegetation
- Leaf litter
- Plantation edges
- Paths and clearings within forested habitats
Their colour and pattern closely resemble dead leaves, shadows and forest-floor debris.
This camouflage can make a motionless animal remarkably difficult to see.
In captivity, the enclosure should reproduce the important functional characteristics of this environment:
Moderate tropical temperatures + humidity + ventilation + extensive ground cover + security + shade.
Gaboon Vipers should not be maintained like hot, dry savannah or desert reptiles.
ADULT SIZE & LIFESPAN
Adults commonly reach approximately:
4–6 ft (1.2–1.8 m)
Females generally become substantially heavier-bodied than males.
Gaboon Vipers are among the heaviest-bodied venomous snakes.
Body mass is therefore as important as length when planning:
- Enclosure dimensions
- Transport
- Veterinary care
- Long-term accommodation
- Emergency arrangements
LIFESPAN
Approximately:
15–20 years
is a realistic captive expectation with excellent husbandry.
Anyone acquiring the species should therefore plan for potentially two decades of specialist care.
ENCLOSURE
Gaboon Vipers are primarily terrestrial.
Floor area is considerably more important than excessive height.
For a substantial adult, approximately:
6 × 3 × 2.5 ft
(approximately 1.8 × 0.9 × 0.75 m)
provides a sensible practical starting point.
Particularly large females benefit from additional floor area.
The enclosure should allow the animal to:
- Move freely
- Fully reposition its body
- Thermoregulate
- Use separate resting locations
- Retreat completely from illumination
- Access clean water
- Remain secure during routine husbandry
Larger accommodation is encouraged where it can be safely and effectively managed.
SECURITY
Accommodation for a dangerously venomous snake requires substantially greater security than a conventional pet-snake enclosure.
The enclosure must be:
- Escape-resistant
- Robust
- Lockable
- Resistant to accidental opening
- Appropriately identified
- Designed to minimise unnecessary exposure during routine maintenance
Doors and access panels must not be capable of being accidentally:
- Knocked open
- Pushed open
- Left unsecured
The enclosure should be located within an appropriately secure room or facility.
Unauthorised people, particularly children, must not have access.
SECONDARY CONTAINMENT
The security of a venomous snake should never depend entirely upon a single enclosure barrier.
The surrounding room or facility should provide an additional level of containment.
The objective is:
SECURE ENCLOSURE + SECURE ROOM/FACILITY
rather than reliance upon one barrier.
The surrounding area should be designed to reduce potential escape routes and prevent unauthorised access.
ROUTINE HUSBANDRY DESIGN
A well-designed enclosure should allow routine jobs such as:
- Water replacement
- Inspection
- Spot cleaning
- Equipment maintenance
to be completed while minimising unnecessary exposure to the snake.
Secure retreat areas or separated enclosure sections can significantly improve safety.
The enclosure itself should form an important part of the keeper’s safety system.
JUVENILE ENCLOSURES
Juveniles require appropriately sized secure accommodation.
Security requirements are just as important for juveniles as adults.
A juvenile Gaboon Viper is already dangerously venomous.
Small size does not mean harmless.
Juvenile accommodation should provide:
- Secure retreat
- Thermal gradient
- Appropriate humidity
- Good ventilation
- Clean water
- Visual cover
- Absolute escape prevention
TEMPERATURE & HEATING
Gaboon Vipers originate primarily from tropical forest environments and should not be maintained excessively hot.
GENERAL AMBIENT
Approximately:
23–26°C (73–79°F)
WARM AREA
Approximately:
28–30°C (82–86°F)
COOL RETREAT
Approximately:
22–24°C (72–75°F)
NIGHT
Approximately:
20–23°C (68–73°F)
A modest nighttime reduction is appropriate.
Avoid severe or prolonged cooling.
OVERHEATING
Overheating is an important husbandry risk.
The fact that the species originates in Africa does not mean that extreme heat is appropriate.
Gaboon Vipers spend much of their lives close to the shaded forest floor.
The snake must always be able to move completely away from the heated area.
Avoid creating an enclosure that remains at approximately 28–30°C throughout.
A genuine thermal gradient is essential.
HEATING EQUIPMENT
Suitable systems may include:
- Properly guarded overhead heating
- Radiant heat panels
- Controlled ambient room heating
All heating equipment must be:
- Thermostatically controlled
- Physically protected
- Securely installed
- Suitable for the humidity level of the enclosure
Avoid exposed heating elements.
Hot rocks should not be used.
TEMPERATURE MONITORING
Use reliable digital thermometers with probes positioned at relevant locations.
Monitor:
- Warm area
- General ambient temperature
- Cool retreat
An infrared thermometer can be useful for verifying surface temperatures.
Remember:
THERMOSTAT SETTING ≠ ACTUAL ENCLOSURE TEMPERATURE
Always measure the conditions the animal is actually experiencing.
HUMIDITY
Maintain approximately:
65–80% relative humidity
with normal fluctuations.
Humidity may temporarily increase during shedding.
The objective is a humid forest environment, not a permanently soaked enclosure.
HUMIDITY DOES NOT MEAN WET
One of the most common misunderstandings with tropical reptile husbandry is confusing:
HIGH HUMIDITY
with:
CONSTANTLY WET SUBSTRATE
The lower layers of substrate can retain moisture while much of the surface remains comparatively dry.
Constantly saturated conditions can encourage:
- Bacterial growth
- Fungal growth
- Skin disease
- Respiratory problems
VENTILATION
Good ventilation is essential.
Aim for:
WARM + HUMID + WELL VENTILATED
not:
WARM + WET + STAGNANT
Effective ventilation should provide air exchange without making it impossible to maintain appropriate humidity.
WATER
Clean fresh water should be continuously available.
The water container should be:
- Stable
- Difficult to overturn
- Easily accessible to the snake
- Appropriate to the animal’s size
- Positioned with safe routine servicing in mind
Some individuals may soak.
Replace contaminated water promptly.
SUBSTRATE
Suitable substrates may include:
- Soil-based forest substrate
- Coco-based substrate
- Cypress-type mulch
- Orchid bark
- Appropriate mixtures of these materials
Clean leaf litter can provide:
- Visual cover
- Naturalistic texture
- Environmental complexity
Substrate should:
- Help buffer humidity
- Provide good traction
- Remain relatively low-dust
- Avoid becoming permanently waterlogged
FURNISHINGS
Gaboon Vipers are heavy terrestrial snakes.
Elaborate climbing structures are unnecessary.
Useful furnishings can include:
- Robust low hides
- Cork bark
- Leaf litter
- Low vegetation
- Visual barriers
- Stable ground-level cover
Avoid unstable objects capable of:
- Collapsing
- Trapping the snake
- Obstructing observation
- Making routine maintenance unnecessarily difficult
HIDES & SECURITY
Provide more than one secure resting opportunity.
The snake should ideally be able to choose between:
- A warmer secure area
- A cooler secure area
Dense visual cover can provide additional security.
The animal should not be forced to remain continuously exposed simply for ease of viewing.
LIGHTING
Provide a clear day/night cycle.
Approximately:
10–12 hours of daytime illumination
is appropriate.
Visible lighting should provide a clear daytime period while retaining extensive shaded areas.
The enclosure should become properly dark at night.
Avoid visible red, blue or purple night bulbs.
UVB
Gaboon Vipers are primarily nocturnal and crepuscular forest-floor snakes.
They are not intense sun-basking reptiles.
UVB should therefore not be approached in the same way as it would be for strongly heliothermic reptiles.
Low-level UVB may nevertheless be offered as part of comprehensive modern husbandry.
The important principle is:
LOW-LEVEL UV + EXTENSIVE SHADE + COMPLETE UV RETREAT
TARGET UVI
A practical low-level target is approximately:
UVI 0.5–1.5
in an accessible illuminated portion of the enclosure.
Provide extensive areas:
below UVI 0.5
and complete shade approaching:
UVI 0
The snake must always be able to avoid UV exposure.
PRACTICAL UVB EQUIPMENT GUIDANCE
The percentage printed on a UVB lamp does not by itself tell you how much ultraviolet radiation will reach the animal.
Actual UVI depends upon:
- Exact lamp model
- Lamp output
- Reflector
- Distance from the animal
- Mesh or screening
- Mounting position
- Lamp age
For a Gaboon Viper, the objective is a low-level linear UVB system capable of producing approximately:
UVI 0.5–1.5
in part of the usable enclosure.
A high-output desert-style UV arrangement is unnecessary and potentially inappropriate.
The appropriate lamp and installation should be selected according to the dimensions and construction of the individual enclosure.
UNDERSTANDING UVB DISTANCE
As a general principle:
CLOSER TO THE LAMP = GENERALLY HIGHER UVI
FARTHER FROM THE LAMP = GENERALLY LOWER UVI
MESH OR SCREENING = USUALLY REDUCES UVI
This is why specifying only a lamp percentage is insufficient.
The mounting distance matters.
UV GRADIENT
A useful arrangement is:
ILLUMINATED AREA: Approximately UVI 0.5–1.5
↓
LOWER-UV AREA: Below UVI 0.5
↓
DEEP SHADE: Approaching UVI 0
The entire enclosure does not need to be covered by UVB.
Providing environmental choice is more important than maximising exposure.
UV METER
A suitable UV Index meter provides the most reliable method of determining the actual UVI within an enclosure.
Measurements should be taken approximately:
AT THE HEIGHT OF THE SNAKE
in the illuminated area.
This measures the exposure available to the animal rather than the output immediately beneath the lamp.
IF YOU DO NOT HAVE A UV METER
Many keepers will not own one.
In that situation:
- Choose a reputable linear UVB system
- Follow the manufacturer’s current distance guidance
- Account for mesh or screening
- Use the appropriate reflector
- Provide extensive shade
- Replace lamps according to current manufacturer guidance
Do not compensate for uncertainty by simply installing the strongest UVB lamp available.
HEAT, UVB & DAYLIGHT ARE DIFFERENT
This is an important principle in reptile husbandry.
HEATING SYSTEM = WARMTH
UVB SYSTEM = ULTRAVIOLET
DAYLIGHT LED = BRIGHT VISIBLE LIGHT
These perform different functions.
A UVB lamp does not automatically provide appropriate heating.
Likewise, a heating lamp does not automatically provide suitable UVB.
The enclosure should provide the appropriate combination of:
- Temperature
- Ultraviolet exposure
- Visible daylight
- Shade
FEEDING
Gaboon Vipers are ambush predators.
Natural prey consists predominantly of vertebrates, particularly small mammals, although birds and other suitable prey may also be taken.
Captive animals can generally be maintained on appropriately sized whole rodents.
Suitable prey may include:
- Mice for smaller juveniles
- Rats as the animal grows
- Appropriately sized larger rodents for substantial adults
Diet and feeding frequency should maintain healthy body condition rather than maximise growth.
FROZEN-THAWED PREY
Where accepted:
APPROPRIATELY PREPARED FROZEN-THAWED PREY
is preferable to routine live vertebrate feeding.
Live rodents can cause serious injuries to snakes.
PREY SIZE
Avoid unnecessarily large meals.
Prey should be appropriate for the individual animal’s:
- Size
- Age
- Body condition
- Feeding history
There is no husbandry advantage to routinely feeding the largest prey an animal is physically capable of swallowing.
FEEDING FREQUENCY
Gaboon Vipers have relatively slow metabolisms.
Overfeeding is a common captive husbandry problem.
JUVENILES
Depending upon prey size and growth:
approximately every 7–14 days
may be appropriate.
SUBADULTS
Approximately:
every 14–21 days
may be appropriate.
ADULTS
Many healthy adults can be maintained on an appropriately sized meal approximately:
every 3–4 weeks
depending upon:
- Individual size
- Prey size
- Activity
- Body condition
These are guidelines rather than rigid feeding schedules.
OBESITY
Gaboon Vipers naturally possess extremely broad bodies.
This can make obesity difficult for inexperienced keepers to recognise.
Do not assume:
“GABOON VIPERS ARE SUPPOSED TO BE FAT.”
They are naturally:
HEAVY-BODIED AND MUSCULAR
Chronic overfeeding can contribute to:
- Excessive fat deposition
- Reduced mobility
- Organ disease
- Reproductive problems
- Reduced longevity
Monitor:
- Body shape
- Weight trends
- Muscle condition
- Feeding history
HANDLING & TEMPERAMENT
Gaboon Vipers should not be casually handled.
Their tendency to remain motionless has contributed to a reputation for being calm.
However:
STILL ≠ SAFE
and:
CALM ≠ HARMLESS
Individuals may defend themselves when disturbed.
The animal’s apparent temperament should never be relied upon as a safety system.
Routine husbandry should be designed around minimising unnecessary physical interaction.
This care sheet deliberately does not provide step-by-step instructions for manipulating or restraining venomous snakes.
Those skills require appropriate specialist practical training and cannot safely be learned from a written care sheet.
COHABITATION
Individual housing is recommended for routine maintenance.
Individual housing allows accurate monitoring of:
- Feeding
- Weight
- Faeces
- Shedding
- Behaviour
- Health
and simplifies safe husbandry.
Temporary reproductive introductions are specialist procedures and should not be confused with routine permanent cohabitation.
CLEANING & ROUTINE CARE
Regularly inspect for:
- Faeces
- Urates
- Shed skin
- Contaminated substrate
- Water contamination
- Mould
- Equipment problems
Routine cleaning should be designed around the enclosure’s containment system rather than requiring unnecessary close interaction with the snake.
Deep cleaning should be planned in advance.
QUARANTINE
All newly acquired animals should undergo strict quarantine.
Approximately:
90 DAYS MINIMUM
is a sensible starting point.
Longer quarantine may be appropriate for:
- Imported animals
- Wild-caught animals
- Animals of uncertain origin
- Animals showing health concerns
Use dedicated husbandry equipment where practical.
Monitor:
- Weight
- Feeding
- Faeces
- Shedding
- Respiration
- Skin
- Mouth
- Behaviour
Veterinary examination and parasite screening are strongly recommended.
COMMON HEALTH CONCERNS
OBESITY
A major preventable captive health problem.
Control feeding according to body condition rather than appetite.
RESPIRATORY DISEASE
Possible signs include:
- Wheezing
- Clicking
- Nasal discharge
- Excess oral mucus
- Persistent abnormal open-mouth breathing
Potential husbandry contributors include:
- Excessive cooling
- Poor ventilation
- Constantly wet conditions
Seek veterinary attention promptly.
STOMATITIS
Possible signs include:
- Oral swelling
- Discharge
- Abnormal mouth position
- Damaged oral tissue
Veterinary assessment is required.
SKIN PROBLEMS
Constantly wet or contaminated substrate can contribute to:
- Dermatitis
- Scale damage
- Bacterial infection
PARASITES
Particularly important in wild-caught or poorly documented animals.
Both external and internal parasites require appropriate investigation and treatment.
DYSECDYSIS
Poor shedding may be associated with:
- Inappropriate humidity
- Dehydration
- Illness
- Parasites
Do not assume every shedding problem simply requires increased spraying.
SIGNS OF GOOD HEALTH
A healthy Gaboon Viper should generally display:
- Clear eyes outside the shedding cycle
- Clean nostrils
- Quiet respiration
- Smooth intact scales
- Good muscular condition
- Appropriate body weight
- Normal tongue-flicking
- Appropriate feeding behaviour
- Normal faeces
- Complete sheds
WHEN TO SEEK VETERINARY ADVICE
Seek appropriately experienced reptile veterinary advice for:
- Respiratory symptoms
- Oral or nasal discharge
- Significant unexplained weight loss
- Severe lethargy
- Repeated regurgitation
- Persistent abnormal food refusal
- Skin lesions
- Burns
- Abnormal swelling
- Persistent abnormal faeces
- Significant injury
- Reproductive problems
- Major unexplained behavioural changes
VETERINARY PLANNING
Finding an appropriate veterinarian after a problem develops is too late.
Before acquiring a Gaboon Viper, identify a veterinarian who is willing and appropriately equipped to provide veterinary care for a dangerously venomous snake.
The veterinary practice should know what species is involved before an appointment is arranged.
Never unexpectedly arrive at a veterinary practice carrying a venomous snake.
EMERGENCY PLANNING
A written emergency plan should exist before the animal enters the premises.
It should identify:
- Exact species kept
- Appropriate emergency medical arrangements
- Relevant emergency contacts
- What should happen if the primary keeper is incapacitated
- Who is appropriately qualified to assist with the animal if necessary
Other responsible people associated with the premises should know that dangerously venomous reptiles are present and know how to summon appropriate assistance without entering the secure reptile area.
Any suspected Gaboon Viper bite requires immediate emergency medical assessment.
Do not rely upon improvised home treatment.
ESCAPE PLANNING
A written escape plan should also exist.
The surrounding facility should be designed to minimise the possibility of an escaped snake leaving the secure reptile area.
People without appropriate specialist competence should not attempt to capture an escaped Gaboon Viper.
Prevention through secure enclosure and facility design is considerably safer than attempting to manage an escape.
BREEDING
Gaboon Vipers are:
VIVIPAROUS — LIVE-BEARING
Females give birth to fully formed young rather than laying eggs.
Breeding should only be undertaken by appropriately experienced keepers with:
- Suitable adult accommodation
- Separate accommodation for offspring
- Appropriate safety systems
- Emergency planning
- Legal compliance
- A realistic long-term plan for every offspring produced
SEXUAL DIMORPHISM
Females generally become:
- Larger
- Heavier
- More massively built
than males.
Sex determination involving physical manipulation should only be undertaken by appropriately experienced people.
REPRODUCTIVE CYCLE
Reproduction may be influenced by seasonal changes in:
- Temperature
- Humidity
- Photoperiod
- Feeding
Breeding manipulation should only be attempted with mature, healthy animals.
Extreme temperature cycling should not be improvised from generic snake-breeding advice.
GESTATION
Gestation is prolonged.
A gravid female may:
- Become substantially heavier
- Reduce feeding
- Change resting behaviour
- Alter thermal preferences
Excellent body condition before breeding is important.
A gravid female should not be excessively fed simply to increase body mass.
LITTER SIZE
Gaboon Vipers can produce large litters.
Approximately:
15–50+ young
may occur, with exceptional litters potentially exceeding this.
This has major implications for anyone considering breeding.
Producing a large litter of venomous snakes requires appropriate secure accommodation and long-term planning for every offspring before breeding takes place.
NEONATES
Newborn Gaboon Vipers are:
VENOMOUS FROM BIRTH
They must never be regarded as harmless because of their small size.
Each offspring requires appropriate secure specialist accommodation and management from birth.
The potential number of offspring is one of the major considerations before attempting to breed this species.
LEGAL CONSIDERATIONS — REPUBLIC OF IRELAND
The Republic of Ireland is not governed by the UK’s Dangerous Wild Animals Act.
A UK Dangerous Wild Animals licence should therefore not be presented as a requirement for keeping a Gaboon Viper in the Republic of Ireland.
However, the absence of the UK DWA framework does not remove a keeper’s legal responsibilities.
Anyone acquiring, keeping, breeding, transporting, importing, exporting or transferring a venomous reptile in the Republic of Ireland should check all legislation and requirements applicable at the time.
Relevant considerations can include:
- Animal health and welfare legislation
- Import and export requirements
- CITES requirements where applicable
- Transport requirements
- Public safety responsibilities
- Property, tenancy or insurance restrictions
Requirements can change.
Always verify the current Republic of Ireland position before acquiring or transferring the species.
LEGAL CONSIDERATIONS — NORTHERN IRELAND
Northern Ireland has separate dangerous wild animal legislation.
Dangerous wild animal keeping is governed by the relevant Northern Ireland framework, including the:
Dangerous Wild Animals (Northern Ireland) Order 2004
Dangerously venomous snakes fall within the NI licensing framework.
Anyone considering keeping a Gaboon Viper in Northern Ireland must check the current requirements with the appropriate authority and obtain any licence or approval required before acquisition.
Do not assume arrangements applicable in Great Britain automatically apply in Northern Ireland.
LEGAL CONSIDERATIONS — GREAT BRITAIN
Great Britain has its own dangerous wild animal licensing framework.
Dangerous wild animal keeping is principally regulated under the:
Dangerous Wild Animals Act 1976
together with the applicable current schedule and subsequent legislation.
Vipers fall within the dangerous wild animal framework.
Anyone intending to keep a Gaboon Viper in England, Scotland or Wales should verify the current licensing requirements with the relevant local authority before acquiring the animal.
IMPORTANT JURISDICTION DISTINCTION
For readers in Ireland and the UK:
REPUBLIC OF IRELAND ≠ NORTHERN IRELAND ≠ GREAT BRITAIN
Their legal frameworks are not interchangeable.
The UK’s Dangerous Wild Animals Act must not be presented as Republic of Ireland legislation.
Likewise, compliance in one jurisdiction does not automatically establish compliance in another.
This is particularly important when animals are:
- Purchased
- Sold
- Transported
- Imported
- Exported
- Moved between jurisdictions
RESPONSIBLE OWNERSHIP CHECKLIST
Before acquiring a Gaboon Viper, ensure you can provide:
- Specialist venomous-reptile experience
- Secure dedicated accommodation
- Lockable escape-resistant enclosure
- Secondary containment
- Appropriate adult floor space
- Correct thermal gradient
- Humidity with effective ventilation
- Clean water
- Suitable forest-floor substrate
- Appropriate lighting
- Low-level optional UVB
- Appropriate whole-prey diet
- Controlled body condition
- Strict quarantine
- Specialist veterinary arrangements
- Written medical emergency plan
- Written escape plan
- Responsible backup arrangements
- Secure transport arrangements
- Correct legal permissions
- Long-term financial resources
- Potentially 15–20 years of specialist care
COMMON HUSBANDRY MISTAKES
Assuming a motionless Gaboon Viper is tame
Stillness is normal behaviour, not evidence of safety.
Keeping the enclosure too hot
This is primarily a tropical forest-floor species.
Providing no cool retreat
The animal must be able to move away from the heated area.
Keeping the substrate permanently soaked
Humidity does not require waterlogged conditions.
Poor ventilation
Warm stagnant humidity can contribute to disease.
Providing insufficient cover
The species relies heavily upon camouflage and security.
Using intense desert UVB
Only low-level optional UV exposure is appropriate.
Choosing UVB solely by percentage
Actual UVI reaching the snake is what matters.
Overfeeding
The naturally heavy body shape can conceal obesity.
Casual handling
This is a dangerously venomous specialist species.
Depending upon temperament for safety
Containment systems, not behaviour, should protect people.
No secondary containment
The enclosure should exist within an appropriately secure surrounding facility.
No emergency plan
Emergency arrangements should exist before acquisition.
No veterinary plan
Appropriate veterinary support should be identified beforehand.
Breeding without planning for offspring
Females can produce very large litters of venomous neonates.
Assuming UK DWA legislation applies in the Republic of Ireland
It does not.
HUSBANDRY SUMMARY

PRACTICAL UVB SUMMARY
For a Gaboon Viper, the aim is:
LOW-LEVEL UVB + EXTENSIVE SHADE + COMPLETE UV RETREAT
A suitable linear UVB installation should provide approximately:
UVI 0.5–1.5
in an accessible illuminated area.
The exact lamp required depends upon:
- Lamp model
- Reflector
- Distance
- Mesh
- Enclosure construction
Remember:
CLOSER = GENERALLY MORE UV
FARTHER AWAY = GENERALLY LESS UV
MESH = USUALLY LESS UV
and:
HEAT = TEMPERATURE
UVB = ULTRAVIOLET
LED = VISIBLE DAYLIGHT
These are different components of reptile lighting and heating.
Do not attempt to expose the entire enclosure to UVB.
Environmental choice is essential.
IMPORTANT INFORMATION
This care sheet provides general husbandry guidance and does not replace species-specific research, specialist practical training, legal advice or veterinary advice. Individual requirements may vary.
The Gaboon Viper (Bitis gabonica) is a dangerously venomous snake capable of causing severe and potentially fatal envenomation. It is suitable only for appropriately experienced specialist keepers with secure facilities, emergency procedures and all legally required permissions.
This care sheet deliberately does not provide step-by-step instructions for handling, restraint or physical manipulation of venomous snakes.
The Dangerous Wild Animals legislation applicable in Great Britain does not apply in the Republic of Ireland. Northern Ireland has its own dangerous wild animal legislation. Always verify the current requirements for the jurisdiction in which the animal will actually be kept.
Captive-bred animals of documented provenance should be strongly preferred.
If you have concerns about an animal’s health or care, consult a suitably experienced reptile veterinarian who is prepared and equipped to work with dangerously venomous reptiles.
