Giant African Land Snail (Lissachatina fulica) Care Sheet
The Giant African Land Snail is a large tropical terrestrial snail native to East Africa. Formerly widely known as Achatina fulica, its currently accepted scientific name is Lissachatina fulica.
These snails are fascinating invertebrates, but their apparently simple appearance can be deceptive. Successful long-term care requires careful attention to temperature, humidity, substrate depth, calcium availability, diet and hygiene.
Lissachatina fulica is also one of the world’s most invasive land snails. Ownership, breeding, transport and sale are restricted or prohibited in some countries and regions. Local legislation must therefore be checked before acquiring this species, and captive animals must never be released outdoors.

Natural Distribution
Lissachatina fulica originated in East Africa.
Human activity has subsequently introduced the species to numerous tropical and subtropical regions around the world.
Introduced populations can become highly invasive.
The species has established populations in parts of:
- Asia
- Pacific islands
- Indian Ocean islands
- Caribbean
- Americas
- Other tropical and subtropical regions
Its invasive potential is one of the most important considerations surrounding captive ownership.
Invasive Species
Giant African Land Snails can reproduce rapidly and consume a very wide variety of plant material.
Where introduced, they may:
- Damage agricultural crops
- Consume ornamental plants
- Compete with native snails
- Affect natural ecosystems
- Become significant agricultural pests
For this reason, regulations surrounding the species can be extremely strict.
Identification
Adult Lissachatina fulica typically possess:
- Large elongated shell
- Pointed shell apex
- Brown shell colouration
- Variable darker longitudinal markings
- Soft grey, brown or darker body
- Two pairs of tentacles
The upper pair of tentacles carries the eyes.
The shorter lower pair is primarily involved in sensory detection.
Adult Size
Adults commonly reach approximately:
10–15 cm shell length
although individual size varies considerably.
Exceptionally large individuals can exceed this.
Size depends upon:
- Genetics
- Nutrition
- Temperature
- Calcium availability
- Health
- General husbandry
A juvenile should therefore not be housed permanently in a very small container.
Lifespan
Giant African Land Snails commonly live approximately:
5–7 years
with some individuals potentially living longer under favourable captive conditions.
They should therefore be considered a multi-year commitment rather than a short-lived novelty pet.
Housing
A secure terrestrial enclosure is required.
Suitable accommodation can include:
- Glass terrariums
- Plastic vivariums
- Modified secure storage enclosures
- Purpose-built invertebrate enclosures
The enclosure must provide:
- Adequate floor area
- Deep substrate
- High humidity
- Ventilation
- Hiding places
- Calcium
- Secure escape prevention
Enclosure Size
Floor space is particularly important.
For one or two adults, an enclosure around:
60 × 30 × 30 cm or larger
provides a useful general starting point.
Larger groups require proportionally more space.
The snail should have room to:
- Travel
- Feed
- Burrow
- Explore
- Select different microclimates
Secure Lid
Giant African Land Snails are excellent climbers.
They can travel across:
- Glass
- Plastic
- Wood
- Decorations
- Enclosure lids
The enclosure therefore requires a secure lid.
Ventilation openings must not be large enough for smaller animals to escape.
Ventilation
High humidity does not mean the enclosure should be sealed without airflow.
Appropriate ventilation helps reduce:
- Stagnant conditions
- Excessive condensation
- Mould
- Bacterial growth
The aim is to maintain a humid but fresh environment.
Temperature
A useful general temperature range is approximately:
21–27°C
with temperatures around:
23–26°C
often suitable for normal activity.
Avoid excessive heat.
Temperatures should always be monitored with a reliable thermometer.
Heating
Depending upon room temperature, supplemental heating may be required.
A heat mat positioned against the side or rear of the enclosure can be used where appropriate.
Heating should be controlled by a suitable thermostat.
Avoid placing uncontrolled heating beneath the entire enclosure.
The snail must be able to move away from the warmest area.
Temperature Gradient
Provide a thermal gradient rather than maintaining every part of the enclosure at exactly the same temperature.
The snail should be able to select:
- Warmer areas
- Cooler areas
- Moist retreats
Behavioural choice is an important component of good husbandry.
Humidity
Giant African Land Snails require a humid environment.
A general target of approximately:
70–90% relative humidity
is often appropriate.
Humidity should be considered alongside:
- Ventilation
- Substrate moisture
- Temperature
- Snail behaviour
The substrate should remain moist but not waterlogged.
Maintaining Humidity
Humidity can be maintained through:
- Appropriate substrate
- Light misting
- Live plants where suitable
- Moist hides
- Controlled ventilation
Do not continuously saturate the enclosure.
Standing water and permanently waterlogged substrate can create unhealthy conditions.
Substrate
A deep moisture-retaining substrate is essential.
Suitable options can include:
- Fertiliser-free organic topsoil
- Coco coir
- Appropriate mixtures of soil and coir
- Leaf litter
The substrate must be free from:
- Pesticides
- Herbicides
- Fertilisers
- Sharp materials
- Harmful chemical additives
Substrate Depth
The substrate should be deep enough for the snail to bury itself completely.
For adults, approximately:
10–15 cm or more
can be appropriate.
Additional depth is particularly useful for egg laying.
Substrate Moisture
The substrate should feel:
damp but not saturated.
When squeezed, it should hold some moisture without releasing large quantities of water.
Very dry substrate can encourage inactivity and dehydration.
Waterlogged substrate can create poor hygiene and anaerobic conditions.
Soil pH
Extremely acidic substrate should be avoided.
Acidic conditions can contribute to shell erosion.
Where necessary, suitable calcium-containing materials can be incorporated carefully into the enclosure to help maintain appropriate conditions.
Hides
Provide several secure hiding locations.
Suitable hides can include:
- Cork bark
- Plastic plant pots positioned safely
- Lightweight artificial hides
- Dense safe vegetation
- Leaf litter
Snails frequently retreat during daylight hours.
Avoid Heavy Decorations
Heavy rocks, ceramic ornaments and other hard objects can present a serious hazard.
Giant African Land Snails frequently climb enclosure walls and lids.
If a snail falls onto a hard object, its shell can crack.
Use lightweight furnishings wherever possible.
Water
Provide access to clean fresh water.
A water dish should be:
- Very shallow
- Stable
- Easy to enter and leave
- Cleaned regularly
Deep water containers should be avoided.
Young snails are particularly vulnerable to drowning.
Lighting
Specialised high-intensity lighting is generally unnecessary.
Provide a normal day/night cycle.
Avoid:
- Continuous bright lighting
- Direct intense sunlight through glass
- Excessive enclosure heating
The enclosure should contain shaded retreats.
UVB
UVB lighting is not generally regarded as essential for routine Giant African Land Snail husbandry when diet and calcium provision are appropriate.
If lighting is used for live plants, ensure that it does not:
- Overheat the enclosure
- Excessively dry the substrate
- Prevent the snail from retreating into shade
Diet
Giant African Land Snails consume a wide variety of plant material.
A captive diet should provide variety rather than relying upon one favourite food.
Suitable foods can include:
- Leafy greens
- Courgette
- Squash
- Sweet potato
- Carrot
- Bell pepper
- Green beans
- Mushroom
- Occasional fruit
- Other safe vegetables
Foods should be washed before feeding.
Leafy Greens
Suitable leafy foods can include:
- Dandelion greens
- Spring greens
- Kale in rotation
- Romaine lettuce
- Plantain leaves from safe sources
- Other appropriate pesticide-free greens
Variety is important.
Cucumber
Cucumber is readily eaten by many Giant African Land Snails.
However, it contains large amounts of water and relatively little nutrition compared with many other vegetables.
It should therefore not become the staple diet.
A snail that is constantly given cucumber may ignore more nutritious foods.
Lettuce
Lettuce can form part of the diet, but nutritional value varies substantially between varieties.
Very watery lettuce should not dominate feeding.
Use more nutritionally useful leafy greens alongside other vegetables.
Vegetables
Useful dietary variety can include:
- Courgette
- Squash
- Sweet potato
- Carrot
- Bell pepper
- Green beans
- Broccoli in moderation
- Mushroom
Rotate foods regularly.
Fruit
Fruit can be offered occasionally.
Suitable examples can include:
- Apple
- Pear
- Strawberry
- Melon
- Mango
Fruit should generally represent a smaller portion of the diet than vegetables and leafy greens because of its sugar content.
Protein
Giant African Land Snails can benefit from occasional appropriate protein-containing foods.
Suitable options vary between husbandry systems and can include small amounts of appropriate unseasoned plant- or invertebrate-based foods.
Protein should supplement a varied plant-based diet rather than dominate it.
Avoid highly processed human foods.
Calcium
Continuous access to an appropriate calcium source is essential.
The simplest commonly used source is:
cuttlebone.
A piece can remain available within the enclosure so the snail can rasp calcium when required.
Calcium is essential for:
- Shell growth
- Shell repair
- Reproduction
- General mineral balance
Cuttlebone
Use plain natural cuttlebone.
Avoid flavoured or chemically treated products.
It can be:
- Placed whole in the enclosure
- Broken into manageable pieces
Replace heavily soiled material as necessary.
Eggshell
Prepared eggshell is sometimes used as an additional calcium source.
However, cuttlebone generally provides a simpler and more convenient continuous calcium source.
Calcium provision should not depend solely upon occasional dietary supplementation.
Shell Growth
Young snails require abundant calcium during growth.
New shell growth appears around the shell opening.
Healthy new growth should develop:
- Smoothly
- Firmly
- Without severe deformation
Poor shell development can be associated with:
- Calcium deficiency
- Inappropriate diet
- Acidic substrate
- Poor environmental conditions
- Trauma
Foods to Avoid
Do not feed foods containing substantial amounts of:
- Salt
- Seasoning
- Added sugar
- Preservatives
- Highly processed ingredients
Particularly avoid:
- Salty foods
- Crisps
- Processed meats
- Seasoned leftovers
- Confectionery
Salt can be extremely dangerous to terrestrial snails.
Salt
Never deliberately expose a pet snail to salt.
Salt causes severe osmotic disruption and tissue damage.
Do not use salt:
- In the enclosure
- For cleaning the snail
- As pest control anywhere the captive snail can contact it
Feeding
Food can be offered regularly and removed when it begins to deteriorate.
The amount required depends upon:
- Snail size
- Number of animals
- Temperature
- Activity
- Food type
Fresh food should not be allowed to rot extensively in the enclosure.
Food Dish
A shallow lightweight food dish can make cleaning easier.
Avoid hard ceramic dishes positioned beneath climbing areas.
A falling snail can damage its shell on hard furnishings.
Lightweight plastic dishes are generally safer.
Nocturnal Behaviour
Giant African Land Snails are primarily active during:
- Evening
- Night
- Humid conditions
During daylight hours they may:
- Hide
- Burrow
- Remain attached beneath furnishings
This is normal behaviour.
Burrowing
Burrowing is natural.
Snails may bury themselves to:
- Rest
- Regulate moisture
- Avoid light
- Lay eggs
- Respond to environmental changes
Do not repeatedly dig up a healthy resting snail simply to check on it.
Inactivity
Temporary inactivity can occur because of:
- Daytime resting
- Temperature
- Low humidity
- Excessive heat
- Environmental disturbance
Persistent inactivity should prompt a review of husbandry conditions.
Estivation
When conditions become excessively hot or dry, a snail may become inactive and form a temporary membrane across the shell opening.
This behaviour is associated with estivation.
Repeated estivation in captivity may indicate unsuitable conditions.
Check:
- Temperature
- Humidity
- Substrate moisture
- Ventilation
Handling
Handling should be gentle and limited.
Before handling:
- Wash hands thoroughly
- Rinse away soap residue
- Moisten hands with clean water
Never pull a snail forcefully from a surface.
Doing so can injure the foot or mantle.
Picking Up a Snail
To move a snail:
- Encourage it gently onto your hand where possible.
- If necessary, carefully slide a clean damp finger beneath the front of the foot.
- Allow the snail to release its grip gradually.
- Support the shell and body.
Never pull sharply on the shell.
Shell Fragility
Although the shell provides protection, it can crack.
Major hazards include:
- Falls
- Hard decorations
- Crushing
- Rough handling
- Calcium deficiency
A severe shell fracture requires specialist veterinary advice where available.
Hygiene
Wash hands thoroughly after handling:
- The snail
- Substrate
- Food remains
- Faeces
- Enclosure furnishings
Also wash produce before feeding.
Good hygiene is particularly important because terrestrial snails can potentially carry parasites and microorganisms.
Rat Lungworm
Some wild populations of Giant African Land Snails can act as intermediate hosts for parasites including the rat lungworm Angiostrongylus cantonensis.
This reinforces the importance of:
- Avoiding wild-caught animals
- Washing hands after contact
- Preventing contact between captive snails and wild rodents
- Washing produce
- Never eating raw or undercooked snails
Responsible captive hygiene substantially reduces avoidable risk.
Cleaning
Spot-clean the enclosure regularly.
Remove:
- Faeces
- Mouldy food
- Rotten vegetation
- Contaminated substrate
- Excessive waste
Avoid unnecessarily replacing all substrate too frequently.
A stable biologically active substrate can be beneficial when appropriately maintained.
Cleaning Products
Avoid harsh household chemicals inside the enclosure.
Where cleaning is necessary, use methods appropriate for invertebrate accommodation and rinse thoroughly.
Snails can be sensitive to chemical residues.
Bioactive Housing
Giant African Land Snails can be maintained in naturalistic or bioactive-style systems.
Possible cleanup organisms can include suitable:
- Springtails
- Isopods
However, species compatibility must be considered carefully.
Cleanup crews do not eliminate the need for enclosure maintenance.
Social Housing
Giant African Land Snails can often be housed with compatible members of the same species when sufficient space and resources are available.
However, they do not require companionship for psychological wellbeing.
Keeping multiple mature snails together dramatically increases the likelihood of reproduction.
Hermaphroditism
Giant African Land Snails are hermaphrodites.
Each mature individual possesses both male and female reproductive organs.
Two compatible mature snails can therefore mate.
After mating, either or both individuals may potentially lay eggs.
Can One Snail Lay Eggs?
Yes.
A snail that has previously mated can potentially retain sperm and later produce fertile eggs.
Therefore, even an apparently solitary snail may lay eggs after being separated from others.
Egg checks remain important for animals with an unknown or previously communal history.
Reproduction
Lissachatina fulica can reproduce prolifically.
A clutch may contain large numbers of eggs, and multiple reproductive events can occur.
This is one of the major reasons the species has such invasive potential.
Captive keepers must have a responsible plan for preventing uncontrolled reproduction.
Egg Checks
Substrate should be checked regularly for eggs when sexually mature animals are maintained.
Eggs are generally:
- Pale
- Rounded
- Buried within substrate
Do not assume that eggs will always be visible on the surface.
Unwanted Eggs
Unwanted eggs should never be placed outdoors, composted alive or released into the environment.
Disposal must comply with local regulations.
Because rules differ between jurisdictions, keepers should establish an appropriate legal method before maintaining reproductively mature animals.
Never Release Eggs
Snail eggs can be just as significant an invasive-species risk as adult snails.
Never dispose of potentially viable eggs:
- In gardens
- Outdoors
- In compost heaps
- In natural areas
Preventing accidental establishment is a fundamental responsibility of ownership.
Breeding
Breeding should only occur when:
- Legal
- Deliberate
- Planned
- Suitable homes exist
- Long-term accommodation is available
Producing large numbers of offspring without homes is irresponsible.
Always check legislation before breeding this species.
Juvenile Care
Young snails require:
- Stable warmth
- Appropriate humidity
- Nutritious varied food
- Continuous calcium
- Safe shallow water access
- Soft furnishings
Avoid hard objects that could damage delicate juvenile shells.
Growth
Juveniles can grow rapidly under favourable conditions.
Healthy development depends upon:
- Genetics
- Nutrition
- Calcium
- Temperature
- Humidity
- Substrate
- General health
Rapid size increase should not be encouraged through an unbalanced diet.
Shell Damage
Minor shell-edge damage may sometimes repair as the snail grows.
More serious damage can involve:
- Deep cracks
- Large missing sections
- Exposed soft tissue
- Mantle injury
Severe shell injuries require specialist assessment where appropriate veterinary expertise is available.
Do not attempt invasive home repairs without appropriate knowledge.
Common Health Problems
Potential problems include:
- Shell damage
- Poor shell growth
- Dehydration
- Excessive inactivity
- Nutritional deficiencies
- Mite infestations
- Reproductive complications
- Environmental stress
Many problems can be prevented through correct husbandry.
Warning Signs
Investigate husbandry and seek specialist veterinary advice where available if the snail shows:
- Persistent unexplained inactivity
- Severe body retraction
- Significant shell deterioration
- Major shell fractures
- Abnormal swelling
- Persistent inability to attach normally
- Unusual discharge
- Strong abnormal odour
- Progressive loss of body condition
Deep Retraction
A snail that remains deeply withdrawn within its shell for prolonged periods may be experiencing:
- Dehydration
- Illness
- Environmental stress
- Severe weakness
Review temperature, humidity and other husbandry immediately.
Persistent or severe cases require specialist advice.
Mites
Small organisms may occasionally be seen around captive snails.
Not every tiny organism is harmful.
Some may simply be harmless substrate fauna.
However, persistent organisms congregating around the:
- Breathing pore
- Mantle
- Body
may require investigation.
Correct identification should precede treatment.
Quarantine
New snails should be quarantined before introduction to established animals.
During quarantine monitor:
- Feeding
- Activity
- Shell condition
- Faeces
- Possible mites
- General condition
Avoid sharing substrate or furnishings between quarantine and established enclosures.
Wild-Caught Snails
Wild-caught Giant African Land Snails should not be collected for captive keeping.
Wild individuals may carry:
- Parasites
- Pathogens
- Pesticide residues
- Unknown health problems
Collection may also be illegal.
Where ownership is permitted, responsibly produced captive animals are preferable.
Escape Prevention
Escape prevention is particularly important because of the species’ invasive potential.
Check regularly for:
- Loose lids
- Damaged vents
- Cable openings
- Gaps around doors
- Small openings accessible to juveniles
Never underestimate a snail’s ability to climb.
Never Release Captive Snails
Never release a Giant African Land Snail into the wild.
This includes releasing animals into:
- Gardens
- Parks
- Woodland
- Farmland
- Compost heaps
- Greenhouses
- Local natural habitats
An unwanted snail must be rehomed or otherwise managed legally and responsibly.
Legal Considerations
Lissachatina fulica is a highly invasive species.
Depending upon location, regulations may restrict or prohibit:
- Possession
- Sale
- Purchase
- Breeding
- Transport
- Import
- Export
Some jurisdictions may prohibit private ownership completely.
Always check current local and national legislation before obtaining this species.
Do not rely solely upon the fact that an animal is advertised for sale.
Responsible Sourcing
Where ownership is legal, obtain animals from a responsible captive source.
Ask about:
- Species identification
- Captive origin
- Approximate age
- Previous diet
- Breeding history
- Legal provenance
Avoid animals of questionable origin.
Responsible Ownership
Before acquiring a Giant African Land Snail, consider:
- Local legality
- Adult size
- Multi-year lifespan
- Heating requirements
- Humidity control
- Substrate requirements
- Continuous calcium provision
- Egg management
- Escape prevention
- Long-term responsibility
The keeper must also be prepared to prevent accidental reproduction and environmental release.
Common Husbandry Mistakes
Common mistakes include:
- Keeping the enclosure too dry
- Maintaining permanently waterlogged substrate
- Insufficient substrate depth
- Feeding mostly cucumber
- Failing to provide continuous calcium
- Using hard decorations
- Allowing excessive heat
- Poor ventilation
- Failing to check for eggs
- Keeping the species without checking legislation
Avoiding these errors substantially improves welfare.
Summary
The Giant African Land Snail (Lissachatina fulica) is an impressive tropical terrestrial gastropod capable of reaching a substantial adult size.
Successful captive husbandry requires a spacious secure enclosure, deep moisture-retaining substrate, warm temperatures, high but well-ventilated humidity, safe hiding places, a varied plant-based diet and continuous access to calcium.
Cuttlebone provides a convenient permanent calcium source, while dietary variety is essential. Cucumber and other watery foods should not dominate the diet.
Reproduction requires particularly careful management. Giant African Land Snails are hermaphrodites, can produce large clutches and have considerable invasive potential. Eggs must be managed responsibly and neither snails nor viable eggs should ever be released outdoors.
Most importantly, legal requirements must be checked before acquisition. Possession and movement of Lissachatina fulica are restricted or prohibited in some jurisdictions because of its status as a major invasive species.
When legally and responsibly maintained, these snails provide an excellent opportunity to observe the behaviour and biology of one of the world’s largest and most successful terrestrial gastropods.
