Overview
The Giant African Land Snail (Achatina fulica) is one of the most recognisable snails in the world. Native to East Africa, it has been introduced to many regions globally — sometimes controversially, due to its invasive potential. As a pet, however, it remains a favourite thanks to its impressive size, docile temperament, and relative ease of care.
Physical Characteristics

| Shell shape | Conical/ovate with a pointed spire |
| Shell colour | Brown with darker banding; varies considerably |

| Lifespan | 5–10 years in captivity |
Natural Habitat & Origin
Achatina fulica originates from coastal East Africa, particularly Kenya and Tanzania. In the wild, it inhabits tropical forests, agricultural land, and gardens. It thrives in warm, humid conditions and is most active after rainfall or at night.
Behaviour & Temperament
Giant African Land Snails are calm, slow-moving animals with no aggressive behaviours. They are nocturnal by nature, spending daylight hours buried or resting. In a well-maintained enclosure, they will become accustomed to handling and may even appear curious about their environment.
They are hermaphrodites — each individual possesses both male and female reproductive organs — and can mate with any other member of their species. If you keep more than one, be prepared for the possibility of eggs.
Diet
These snails are voracious eaters with a broad diet:
- Leafy greens: Romaine lettuce, kale, spinach, dandelion leaves
- Vegetables: Cucumber, courgette, sweet potato, carrot
- Fruits: Banana, apple, papaya (in moderation)
- Calcium: Cuttlebone or crushed eggshells must be available at all times to support shell growth
Avoid citrus, onion, garlic, salt, and any processed or heavily seasoned foods.
Housing Requirements
- Enclosure size: Minimum 30 x 30 x 30 cm for one adult; larger is always better
- Substrate: 8–10 cm of coconut coir or chemical-free compost to allow burrowing
- Humidity: 75–95%
- Temperature: 20–28°C (68–82°F)
- Ventilation: Mesh top or side panels are essential
Health Considerations
GALS are hardy snails, but watch for the following:
- Shell damage: Cracks or holes in the shell can be caused by falls or calcium deficiency. Minor cracks often heal on their own with adequate calcium.
- Lethargy: Usually caused by low humidity, incorrect temperature, or a need to hibernate. Review enclosure conditions first.
- Overbreeding: If keeping multiple snails, remove eggs promptly unless you intend to raise juveniles.
Legal Status
It is important to note that Achatina fulica is classified as an invasive species in many countries, including the United States, where it is illegal to own, import, or transport without a permit. Always check your local regulations before acquiring any snail species.
Is the Giant African Land Snail Right for You?
If you want a large, handleable, long-lived pet that is genuinely fascinating to watch and care for, the GALS is hard to beat. Their size makes them easier to observe than smaller snails, and their slow pace makes them ideal for patient keepers of all ages.
