Papuan Python (Apodora papuana) Care Sheet
The Papuan Python is a very large, powerful python native to New Guinea. Formerly known widely as the Papuan Olive Python, it is the sole recognised species within the genus Apodora and is one of the largest snakes occurring on the island.
Papuan Pythons are impressive animals with smooth, highly iridescent scales. Their colouration can appear olive, brown, grey or almost black depending upon the individual, lighting and physiological state. Despite their considerable size, established individuals can be relatively calm, although temperament varies considerably.
Their adult size, physical strength, strong feeding response and substantial enclosure requirements make them suitable only for experienced keepers capable of providing appropriately large and secure accommodation throughout the animal’s life.

Taxonomy
The Papuan Python is currently recognised as:
Apodora papuana
It was historically classified within the genus Liasis and may therefore still appear in older literature as:
Liasis papuana
The species is sufficiently distinct that it is now placed within its own genus, Apodora.
Older references and reptile trade listings may therefore use different scientific names for the same species.
Natural History
Papuan Pythons are native to New Guinea.
They occupy a variety of habitats including:
- Tropical forest
- Savanna
- Woodland
- Forest margins
- Wetland areas
- River systems
They are predominantly terrestrial but are capable of climbing and swimming.
Natural retreats may include:
- Burrows
- Hollow logs
- Dense vegetation
- Rock crevices
- Fallen timber
Their large size allows adults to take a wide variety of vertebrate prey.
Appearance
Papuan Pythons generally display relatively uniform dorsal colouration.
Individuals may appear:
- Olive-brown
- Dark brown
- Grey
- Bronze
- Nearly black
Their smooth scales can produce remarkable iridescence under suitable lighting.
Colours reflected from the scales may include:
- Blue
- Purple
- Green
- Bronze
- Rainbow tones
The underside is generally considerably lighter.
Colour Change
Papuan Pythons can display noticeable changes in colour and tone.
An individual may appear considerably lighter or darker at different times.
Changes can be associated with factors including:
- Light
- Temperature
- Shedding cycle
- Physiological state
This ability can make the same animal appear surprisingly different between photographs.
Adult Size
Papuan Pythons are very large snakes.
Adults commonly reach approximately:
250–350 cm (8–11.5 ft)
although exceptional individuals may become larger.
Females can become particularly substantial.
Adult size should be considered carefully before acquiring a juvenile.
A mature Papuan Python is:
- Long
- Muscular
- Powerful
- Capable of exerting considerable force
Accommodation and handling arrangements suitable for a juvenile will be completely inadequate for an adult.
Enclosure
Papuan Pythons require very large accommodation.
For an average adult, approximately:
300 × 120 × 120 cm (10 × 4 × 4 ft)
should be considered a practical minimum starting point rather than an ideal maximum.
Larger individuals should receive correspondingly larger accommodation.
Purpose-built large enclosures or dedicated reptile rooms can provide considerably better opportunities for natural movement.
The enclosure should provide:
- Extensive floor space
- Multiple retreats
- Strong climbing structures
- Large water container
- Appropriate substrate
- Thermal gradient
- Environmental enrichment
Juvenile Enclosures
Juveniles can initially be maintained in smaller secure accommodation.
Provide:
- Warm-side hide
- Cool-side hide
- Fresh water
- Suitable substrate
- Climbing opportunities
- Environmental cover
Young animals may feel insecure in barren environments.
Numerous appropriately sized retreats can help reduce stress.
The enclosure should be upgraded progressively as the snake grows.
Enclosure Security
Papuan Pythons are exceptionally strong.
Adult accommodation requires:
- Heavy-duty construction
- Strong doors
- Reliable locks
- Secure ventilation
- Protected cable openings
Large individuals can exert considerable force against doors and furnishings.
All branches, shelves and heavy decorations must be securely anchored.
Heating and lighting equipment must be inaccessible to the snake.
Hides
Provide multiple secure retreats.
At minimum, include:
- One warm-side hide
- One cool-side hide
Additional retreats at intermediate temperatures are strongly encouraged.
Suitable options include:
- Large cork structures
- Hollow logs
- Artificial rock retreats
- Purpose-built hides
Large snakes still require the opportunity to conceal themselves completely.
Climbing Opportunities
Although primarily terrestrial, Papuan Pythons are capable climbers.
Strong elevated structures provide valuable enrichment.
Suitable options include:
- Heavy branches
- Logs
- Shelves
- Platforms
All structures must safely support the full weight of the snake.
Avoid unstable or excessively high structures that could cause injury if the snake falls.
Substrate
Suitable substrates include:
- Reptile-safe soil
- Coconut husk
- Cypress-type reptile substrate
- Naturalistic soil mixtures
- Other appropriate moisture-retaining substrates
The substrate should support moderate humidity without remaining permanently saturated.
Avoid:
- Cedar
- Pine
- Artificially scented substrate
- Excessively dusty materials
Large enclosures can incorporate varying substrate depths and textures to increase environmental complexity.
Temperature & Heating
Provide a clear thermal gradient.
Suitable temperatures are approximately:
Basking/warm area: 31–33°C
Warm ambient area: approximately 27–29°C
Cooler area: approximately 24–26°C
Night: approximately 22–25°C
The snake must always be able to move away from the warm area.
The entire enclosure should never be maintained at basking temperature.
Basking Area
A very large snake requires a broad basking zone.
A single small heat source may warm only a small section of the animal.
Several appropriately positioned heat sources may be necessary to produce a basking area capable of warming a substantial portion of the snake evenly.
Surface temperatures should be checked using an infrared thermometer.
Heating
Suitable heating systems may include appropriately installed:
- Halogen basking lamps
- Deep heat projectors
- Ceramic heat emitters
depending upon enclosure design.
All heating equipment must be appropriately thermostatically controlled.
Internally mounted heat sources accessible to the snake must be securely guarded.
Large pythons can damage poorly installed guards and fittings.
Humidity
Papuan Pythons originate from environments where humidity can be relatively high.
A useful general range is approximately:
60–80% relative humidity
with natural fluctuations.
Humidity may temporarily rise following:
- Misting
- Rain simulation
- Overnight cooling
However, good ventilation remains essential.
The enclosure should not remain continuously saturated or stagnant.
Humidity & Ventilation
High humidity does not require constantly wet substrate.
The enclosure should experience cycles of:
- Increased humidity
- Surface drying
- Fresh air exchange
Persistently wet and poorly ventilated conditions can contribute to:
- Scale problems
- Bacterial growth
- Fungal growth
- Respiratory disease
Humid retreats can provide additional localised moisture.
Water
Fresh drinking water should be available at all times.
Provide a large, stable water container.
Where practical, the container should allow the snake to soak.
Papuan Pythons are capable swimmers and may voluntarily enter water.
Water should be:
- Checked daily
- Changed regularly
- Replaced immediately when contaminated
Large snakes can contaminate water rapidly, so the container should be designed for easy cleaning.
Swimming
Papuan Pythons are capable swimmers.
Where enclosure size allows, a larger aquatic area can provide environmental enrichment.
However:
- Water must remain clean
- Entry and exit must be easy
- Extensive dry areas must remain available
- The water area must not replace necessary terrestrial space
Lighting
Provide a consistent day/night cycle.
Approximately:
10–12 hours of light per day
is suitable.
Bright visible daytime lighting can help establish a strong photoperiod.
The enclosure should become genuinely dark at night.
Avoid red, blue or purple nighttime bulbs.
UVB
Low-level UVB can be incorporated into modern Papuan Python husbandry.
A useful exposed basking target may be approximately:
UVI 1–2
with shaded retreats providing negligible exposure.
The snake must always be able to regulate its own exposure.
Actual UV intensity depends upon:
- Lamp output
- Reflector
- Distance
- Mesh
- Basking position
Environmental Enrichment
Papuan Pythons are active animals that benefit from environmental complexity.
Suitable enrichment includes:
- Large logs
- Strong branches
- Multiple hides
- Different substrate depths
- Large water areas
- Elevated platforms
- Vegetation
- Leaf litter
- Scent trails
- Occasional changes in enclosure layout
The environment should encourage:
- Exploration
- Climbing
- Swimming
- Concealment
- Foraging
- Thermoregulation
A large enclosure should not simply be an empty box containing a water bowl and hide.
Diet
Papuan Pythons are carnivorous constrictors.
Wild prey may include:
- Rodents
- Other mammals
- Birds
- Reptiles
- Other appropriately sized vertebrates
Large adults are capable of consuming substantial prey.
However, captive animals should not routinely be offered the largest prey they are physically capable of swallowing.
Captive Diet
Appropriate whole prey may include:
- Rats
- Rabbits where appropriately sized
- Poultry
- Other suitable whole vertebrate prey
Dietary variety can be beneficial.
Whole prey provides:
- Muscle
- Bone
- Organs
- Fat
- Micronutrients
Prey size and frequency should be adjusted according to the snake’s body condition.
Frozen-Thawed Prey
Appropriately prepared frozen-thawed prey is strongly preferred.
This eliminates the risk of live prey injuring the snake.
Frozen prey should be:
- Completely thawed
- Appropriately warmed
- Presented using long feeding tongs
Never microwave whole frozen prey because uneven heating can create dangerous internal hot spots.
Prey Size
Offer prey that creates a modest visible swelling rather than extreme distension.
Oversized meals can increase the risk of:
- Regurgitation
- Digestive difficulty
- Injury
- Excessive calorie intake
Large constrictors should not routinely be power-fed.
Feeding Frequency
Juveniles can generally be fed approximately:
Every 5–7 days
depending upon prey size and growth.
Subadults may generally be fed approximately:
Every 7–14 days.
Healthy adults may generally be fed approximately:
Every 14–21 days
depending upon:
- Prey size
- Body condition
- Activity
- Reproductive status
Large adults do not require constant heavy feeding.
Feeding Response
Papuan Pythons can possess extremely strong feeding responses.
Large individuals can strike rapidly and with considerable force.
Useful management practices include:
- Long feeding tongs
- Washing hands after handling prey
- Avoiding prey scent during routine maintenance
- Establishing predictable enclosure routines
- Target or tap training
Always establish the snake’s position and behaviour before entering or reaching into the enclosure.
Obesity
Obesity is a significant concern in captive large constrictors.
Potential causes include:
- Oversized prey
- Excessively frequent feeding
- Limited enclosure space
- Insufficient activity
Monitor:
- Body shape
- Muscle tone
- Activity
- Weight trends
A healthy Papuan Python should remain muscular rather than excessively rounded.
Target Training
Target training can be particularly useful with large pythons.
The snake can learn to associate a specific target with feeding.
This can help distinguish between:
- Feeding sessions
- Cleaning
- Handling
- Routine enclosure access
Consistent training can make management considerably safer and less stressful.
Handling
Captive-bred Papuan Pythons may become relatively tolerant of routine handling.
However, even a calm adult is an extremely powerful constrictor.
When handling:
- Move calmly
- Support the body
- Avoid grabbing the head
- Avoid unnecessary restraint
- Allow controlled movement
Handling protocols should reflect the animal’s adult size and strength.
Large-Constrictor Safety
Keepers should develop safe management practices before the animal reaches adult size.
For large adults, having another capable adult present during handling or major enclosure maintenance is a sensible precaution.
Never:
- Place a large python around the neck
- Allow uncontrolled access to the face
- Handle immediately after presenting prey
- Underestimate an apparently calm animal’s strength
Responsible management protects both keeper and snake.
Defensive Behaviour
A defensive Papuan Python may:
- Hiss
- Form an S-shaped posture
- Strike
- Attempt to retreat
Persistent defensive behaviour may be associated with:
- Inadequate hiding opportunities
- Excessive disturbance
- Incorrect environmental conditions
- Feeding-associated behaviour
- Stress
Husbandry should be reviewed where defensive behaviour is excessive.
Handling After Feeding
Avoid unnecessary handling for at least:
48–72 hours after feeding
and longer following substantial meals.
Large meals require considerable digestion time.
Allow the snake to digest undisturbed at appropriate temperatures.
Shedding
Signs of an approaching shed include:
- Dull colouration
- Reduced iridescence
- Cloudy or blue eyes
- Reduced activity
- Possible feeding refusal
Appropriate humidity and hydration generally support normal shedding.
After shedding, check:
- Eye caps
- Tail tip
- Overall skin
Repeated incomplete shedding indicates that humidity, hydration or general health should be reviewed.
Housing Multiple Snakes
Individual housing is generally recommended.
Papuan Pythons do not require companionship.
Separate housing allows accurate monitoring of:
- Feeding
- Faeces
- Shedding
- Body condition
- Health
It also prevents competition and feeding accidents.
Animals should only be introduced for breeding under controlled conditions.
Health
Potential health concerns include:
- Obesity
- Respiratory infections
- Mouth infections
- Scale problems
- Burns
- Dehydration
- Retained shed
- External parasites
- Internal parasites
- Regurgitation
- Reproductive complications
Warning signs include:
- Significant unexplained weight loss
- Persistent refusal to feed
- Repeated regurgitation
- Wheezing
- Open-mouth breathing
- Nasal discharge
- Excessive saliva
- Mouth swelling
- Neurological abnormalities
- Significant behavioural changes
Persistent or serious symptoms require assessment by a suitably experienced reptile/exotic veterinarian.
Respiratory Disease
Respiratory problems can be associated with inappropriate combinations of:
- Temperature
- Humidity
- Ventilation
- Hygiene
Possible signs include:
- Wheezing
- Clicking
- Nasal discharge
- Excessive saliva
- Open-mouth breathing
Suspected respiratory disease requires veterinary assessment.
Environmental conditions should also be reviewed.
Scale Problems
Persistently wet or dirty substrate can contribute to skin and scale problems.
Check the underside regularly for:
- Redness
- Discolouration
- Raised scales
- Blistering
- Damaged scales
The snake should always have access to clean, relatively dry terrestrial areas.
Quarantine
All newly acquired Papuan Pythons should undergo quarantine away from established reptiles.
During quarantine:
- Record body weight
- Monitor feeding
- Examine faeces
- Check skin
- Monitor breathing
- Check carefully for mites
- Observe behaviour
- Maintain separate equipment
Veterinary faecal testing may be appropriate, particularly for animals of uncertain origin.
Captive-bred animals should be strongly preferred.
Captive-Bred vs Wild-Caught
Captive-bred Papuan Pythons should be strongly preferred.
Animals of uncertain or wild origin may present increased risks of:
- Parasites
- Dehydration
- Stress
- Defensive behaviour
- Feeding difficulties
- Unknown health history
A well-established captive-bred animal with documented feeding history is preferable.
Sexing
Papuan Pythons can be sexed using established professional snake-sexing techniques.
These procedures should only be performed by an experienced person.
Incorrect probing can cause serious injury.
External appearance should not be relied upon as the sole method of sex determination.
Breeding
Papuan Pythons are egg-laying snakes.
Breeding should only be attempted with healthy mature animals in excellent body condition.
Successful breeding requires knowledge of:
- Accurate sexing
- Sexual maturity
- Seasonal cycling
- Pair introduction
- Courtship
- Female condition
- Egg development
- Egg laying
- Incubation
- Hatchling husbandry
Large adults should not simply be housed together permanently for breeding purposes.
Seasonal Cycling
Captive breeding programmes may incorporate controlled seasonal changes.
These may involve gradual alterations to:
- Nighttime temperatures
- Photoperiod
- Humidity
- Feeding
Only healthy animals in appropriate body condition should undergo deliberate cycling.
Environmental changes should be gradual rather than abrupt.
Pair Introduction
Breeding introductions should be carefully monitored.
Observe for:
- Courtship
- Copulation
- Stress
- Defensive behaviour
Animals should be separated if either individual appears persistently stressed.
Accurate breeding records should be maintained.
Egg Laying
Females require access to a secure laying area containing appropriate moisture-retaining substrate.
The nest should provide:
- Privacy
- Appropriate moisture
- Suitable temperature
- Sufficient space
Females should be monitored carefully during the reproductive period.
Difficulty laying eggs can become a veterinary emergency.
Maternal Incubation
Female Papuan Pythons may coil around their eggs.
Maternal incubation may be possible where environmental conditions are carefully controlled.
Artificial incubation may also be used.
The chosen method should be researched thoroughly before breeding takes place.
Artificial Incubation
Eggs require carefully controlled:
- Temperature
- Moisture
- Gas exchange
Eggs should not be unnecessarily rotated after development has begun.
Breeders should research current species-specific incubation protocols before attempting reproduction.
Hatchlings
Hatchlings require:
- Secure individual accommodation
- Appropriate thermal gradients
- Multiple small hides
- Fresh water
- Suitable substrate
- Appropriately sized prey
Young animals should be monitored individually for:
- First shed
- Feeding
- Body weight
- Defecation
- Normal development
Growth should be steady rather than accelerated through excessive feeding.
Responsible Sourcing
Captive-bred Papuan Pythons should be strongly preferred.
Before acquiring an animal, establish where possible:
- Captive-bred status
- Age
- Sex
- Feeding history
- Health history
- Provenance or lineage
Prospective owners should have a realistic plan for accommodating the animal at full adult size before purchasing a juvenile.
Responsible Ownership
Papuan Pythons can live for 20–30 years or longer with appropriate care.
Before acquiring one, consider:
- Potential adult length exceeding 3 metres
- Very large enclosure requirements
- Considerable physical strength
- Strong feeding response
- Whole-prey feeding
- Heating requirements
- Specialist veterinary care
- Safe handling procedures
- Long lifespan
A small juvenile can eventually become an exceptionally powerful adult.
The full scale of the animal’s future accommodation and management requirements should therefore be considered before acquisition.
Never release a captive snake into the wild.
Summary
The Papuan Python is a spectacular and powerful New Guinea python characterised by its considerable adult size, smooth scales, variable dark colouration and exceptional iridescence.
Successful husbandry depends upon providing a very large and secure enclosure, broad heated areas, multiple retreats, strong climbing structures, clean water, appropriate humidity combined with good ventilation, extensive environmental enrichment and carefully controlled whole-prey feeding.
Its potential adult size and strength make Apodora papuana an advanced species requiring substantial long-term planning and responsible handling procedures.
With appropriate space, environmental management, controlled feeding and responsible long-term care, the Papuan Python can thrive in captivity for decades.
