Achatina fulica is a small to medium-sized land snail originally from East Africa. It is one of the three most commonly farmed snail species in Nigeria, alongside Achatina achatina and Archachatina marginata. If you are asking “what is Achatina fulica and how do I grow and care for it in Nigeria,” this guide gives you a clear, honest answer based on over 12 years of hands-on farming experience at Zendric.
Achatina fulica is widely known as the Giant African Land Snail, though it is noticeably smaller than its Nigerian relatives. It is popular among beginner farmers because it grows faster and produces far more eggs than other species. Understanding its nature, habitat needs, feeding habits, and care requirements is important before you decide to raise it on your farm.
1. What is Achatina Fulica Snail?
Achatina fulica is a species of large, air-breathing land snail belonging to the family Achatinidae. It is native to East Africa, particularly Kenya, Tanzania, and the coastal regions of Mozambique. Today, it has spread to many tropical countries, including Nigeria, through trade and accidental introduction.
The name “fulica” comes from the Latin word for coot, a type of bird, because of the snail’s dark coloring. In Nigeria, many people call it the “small giant snail” or confuse it with Achatina achatina because both carry the “Achatina” name.
According to the Food and Agriculture Organization of the United Nations (FAO), Achatina fulica is now considered one of the most widespread land snails in the world. It adapts easily to different climates and soils, which is why it thrives across Nigeria’s diverse geographic zones.
Achatina fulica is not the same species as the native West African snails. It was introduced, not indigenous, but it has adapted well to the Nigerian climate. It is widely farmed because it breeds rapidly and reaches a sellable size faster than other species.
2. Achatina Fulica vs Other Nigerian Snail Species
Before you commit to farming Achatina fulica, you need to know how it compares to the other two species commonly farmed in Nigeria. Getting this wrong can cost you time and money.
At Zendric, we have written a detailed comparison guide: Achatina achatina vs Archachatina marginata: The Complete Guide. Below is a quick comparison that includes Achatina fulica.
| Feature | Achatina Fulica | Achatina Achatina | Archachatina Marginata |
|---|---|---|---|
| Common Name | Giant African Land Snail | Tiger Snail / Giant Ghana Snail | Giant West African Snail |
| Mature Weight | 50g to 150g | 300g to 500g+ | 150g to 250g |
| Shell Length | 7cm to 12cm | 18cm to 25cm | 12cm to 18cm |
| Time to Market | 6 to 10 months | 12 to 18 months | 8 to 12 months |
| Eggs Per Clutch | 100 to 400 | 6 to 12 | 8 to 15 |
| Clutches Per Year | 4 to 8 | 4 to 6 | 4 to 6 |
| Market Price (per kg) | N1,500 to N2,500 | N3,500 to N4,500 | N2,800 to N3,800 |
| Best For | Volume sales, quick cash flow | Premium markets, export | Beginners, mid-range markets |
As you can see, Achatina fulica sells for a lower price per kilogram than its Nigerian counterparts. However, its rapid breeding rate and shorter grow-out period make it attractive for farmers who need faster returns.

3. Physical Characteristics of Achatina Fulica
Knowing how to identify Achatina fulica accurately helps you avoid buying the wrong species from market traders.
Shell Appearance
The shell of Achatina fulica is elongated and cone-shaped with a pointed apex. The coloring is usually brown with narrow, darker brown stripes running across the shell. The surface is smooth compared to the more textured shells of Achatina achatina.
Adult shells typically grow between 7 and 12 centimeters in length. The shell is thinner and lighter than that of Achatina achatina or Archachatina marginata.
Body Features
The foot and body are greyish-brown to dark brown. The tentacles are relatively shorter than those of Achatina achatina. The body is firm and muscular but noticeably smaller when fully grown.
Growth Stages
| Growth Stage | Age | Average Weight | Shell Length |
|---|---|---|---|
| Hatchling | 0 to 3 weeks | 0.1g to 0.5g | 0.5cm to 1cm |
| Juvenile | 1 to 4 months | 5g to 40g | 2cm to 6cm |
| Sub-adult | 4 to 7 months | 40g to 100g | 6cm to 10cm |
| Market-Ready | 6 to 10 months | 100g to 150g | 10cm to 12cm |
| Fully Mature | 10 months and above | 150g to 200g | 12cm+ |
4. Setting Up a Farm for Achatina Fulica in Nigeria
The setup process for Achatina fulica is similar to other snail species but with a few differences because of its smaller size and faster breeding rate.
Choosing a Location
Achatina fulica thrives in warm, humid environments. It does well in shaded outdoor pens or indoor setups. Like other snail species, it prefers:
- Temperatures between 20 and 30 degrees Celsius
- Relative humidity of 70 to 90 percent
- Shaded locations away from direct afternoon sun
Avoid waterlogged areas. Despite Achatina fulica’s high adaptability, standing water will kill your snails and encourage disease.
Types of Housing
You can use the same housing types recommended for other species. At Zendric, we regularly guide farmers through their setup choices. The most practical options in Nigeria are:
Wooden hutch boxes are the most affordable and suitable for beginners. They are easy to build with local materials and can be expanded as your farm grows.
Concrete pens are more durable and easier to sanitize. They are ideal when you scale beyond 500 snails.
Wire mesh free-range enclosures work well if you have a shaded outdoor space and need to manage large numbers. However, monitoring and security require more effort.
Space Requirements
Because Achatina fulica is smaller, you can keep more snails per square meter than with Achatina achatina. A reasonable stocking density is:
- 10 to 15 adult snails per square meter (for comfort and growth)
- For 200 adults, plan for at least 15 to 20 square meters of pen space
Overcrowding still causes stress, disease, and reduced growth, even with this smaller species. Do not push the numbers too high.
Soil Requirements
Achatina fulica, like all snail species, needs loamy, well-draining soil with a pH between 6.0 and 7.5. The soil must:
- Be moist but not waterlogged
- Contain calcium (add crushed snail shells, bone meal, or ground limestone)
- Be free of pesticides, salt, and chemical fertilizers
- Be at least 10 to 15 centimeters deep to allow egg-laying
Change your pen soil every 2 to 3 months to keep disease levels low. You can read our guide on How to Sterilize Soil for Snail Farming Using Hot Water Method for a safe and affordable way to prepare your bedding soil.
5. How to Feed Achatina Fulica Snails
Feeding is one of the most important parts of Achatina fulica care. It directly affects how fast your snails grow and how much you earn.
What Achatina Fulica Eats
Achatina fulica is a herbivore. It eats plant material, including:
- Leaves: Pawpaw, waterleaf, fluted pumpkin (ugwu), plantain leaves, and cocoyam leaves
- Vegetables: Lettuce, cabbage, cucumber, and sweet potato leaves
- Fruits: Overripe pawpaw, watermelon, banana, and soft tomatoes
- Calcium sources: Crushed snail shells, oyster shell powder, bone meal, or food-grade chalk
Calcium is essential for Achatina fulica. Without enough calcium, shells become weak and growth slows down. Read our guide on How to Make Calcium Powder from Egg Shells for Snails for an affordable homemade calcium supplement.
Feeding Schedule
Feed Achatina fulica in the evening, around dusk. Snails are nocturnal and eat the most at night. A consistent feeding schedule improves feed conversion and growth rates.
An adult Achatina fulica eats approximately 20 to 40 grams of food per day. Because the species is smaller, feed consumption is lower than with Achatina achatina, which helps keep feed costs down.
Always remove uneaten food the next morning. Rotting food attracts pests, grows bacteria, and can make your snails sick.
Foods to Avoid
Never feed Achatina fulica the following:
- Salt or any salty food (even a tiny amount can kill snails)
- Citrus fruits such as orange, lemon, and lime
- Onions and garlic
- Spicy peppers
- Processed human food of any kind
6. Breeding and Reproduction of Achatina Fulica
The most impressive thing about Achatina fulica is its breeding capacity. This is the main reason many farmers choose it.
Key Reproductive Facts
Like all Achatina snails, Achatina fulica is hermaphroditic. Each snail has both male and female organs. However, two snails are still needed to mate. Self-fertilization does not occur under normal conditions.
| Reproductive Feature | Detail |
|---|---|
| Age of First Mating | 5 to 8 months |
| Eggs Per Clutch | 100 to 400 eggs |
| Number of Clutches Per Year | 4 to 8 |
| Incubation Period | 11 to 15 days |
| Hatchling Survival Rate | 65 to 80 percent (with proper care) |
This is a large number of eggs compared to Achatina achatina, which lays only 6 to 12 eggs per clutch. One Achatina fulica breeder can produce hundreds of hatchlings per year if conditions are good.
Managing the High Breeding Rate
The high egg count is both an advantage and a challenge. If you do not manage the population, you will quickly become overstocked.
Plan your pen space before breeding season begins. Set aside a separate hatchling pen and move newly hatched snails away from adults immediately. Adult snails can crush hatchlings accidentally.

7. Seasonal Care for Achatina Fulica in Nigeria
Nigeria’s two main seasons, the rainy season and the dry Harmattan season, affect Achatina fulica differently. Knowing what to do in each season will protect your investment.
Rainy Season (April to October)
This is the most natural growing season for Achatina fulica. Growth is fastest, feeding activity is highest, and breeding is most productive. Your main concerns are:
Flooding: Ensure good drainage in and around your pen. Achatina fulica snails can drown in waterlogged conditions.
Overcrowding from rapid breeding: Monitor your hatchling pen closely. Separate growing snails by size to prevent injury.
Fungal infections: High humidity combined with poor ventilation encourages shell fungus. Allow adequate airflow in your pen at all times.
Harmattan Season (November to March)
Harmattan is the hardest season for Achatina fulica care in Nigeria. The dry air causes snails to seal themselves into their shells (aestivation) and can kill dehydrated snails within days.
Key care steps during Harmattan:
- Water your pen soil every morning and evening
- Cover the top of your pen with shade netting or banana leaves to trap moisture
- Mist the pen walls twice daily with a spray bottle
- Check for snails that appear inactive or sealed for too long and rehydrate the soil around them
- Avoid opening the pen unnecessarily during the hottest parts of the day

8. Common Health Problems and How to Prevent Them
Achatina fulica is relatively hardy, but it is still vulnerable to several health problems common in Nigerian snail farms.
Shell Problems
Thin or cracked shells are almost always a sign of calcium deficiency. Add calcium supplements to your feeding plan daily. Crushed snail shells, oyster shell powder, and bone meal are all affordable options available in Nigeria.
Shell fungus appears as white or green patches. It results from poor ventilation combined with excess moisture. Improve airflow, isolate affected snails, and review your watering schedule.
Body Infections
Bacterial infections show as soft, discolored, or bad-smelling flesh. Isolate any infected snail immediately and remove dead snails from the pen the moment you spot them. Leaving dead snails in the pen spreads disease rapidly.
Predators and Pests
Common threats to Achatina fulica in Nigerian farm settings include:
- Soldier ants (they attack in large numbers and can wipe out a pen overnight)
- Lizards and geckos
- Rats and mice
- Frogs (they compete for food and moisture)
Use wire mesh with openings no larger than 5mm to seal your pen. Stand pen legs in dishes of water or ash to prevent ant invasion. Check for gaps in the mesh regularly.
Prevention Practices
The best approach to snail health is consistent prevention:
- Clean the pen at least once per week
- Remove uneaten food every morning
- Change the bedding soil every 2 to 3 months
- Maintain correct humidity levels
- Quarantine any new snails for 2 weeks before placing them in your main pen
9. When and How to Sell Achatina Fulica Snails
Timing and market choice affect how much profit you actually take home.
Best Times to Sell
Snail prices in Nigeria generally rise during these periods:
- December and January (festive season)
- Easter period (March and April)
- During and after periods when wild snail supply drops (dry season months)
You can read our full guide on When to Sell Snails for the Highest Price for a detailed breakdown of market timing by month.
Where to Sell Achatina Fulica
Because Achatina fulica is smaller and cheaper per kilogram, it sells best in volume markets rather than premium hotel channels. Good market options include:
Local food markets where traders buy in bulk. Lagos markets like Mile 12, Owode Onirin, and Ketu handle large snail volumes regularly.
Direct consumer sales via WhatsApp and Instagram are growing fast among city buyers who want fresh snails delivered to their homes.
Processors and cold chain buyers who buy large quantities for processing, packaging, and resale in supermarkets and eateries.
Avoid targeting premium hotel restaurant buyers with Achatina fulica unless your snails reach 150 grams or more. Hotels prefer the larger species for portion size and presentation.
10. Profitability of Achatina Fulica Farming in Nigeria
Let us look at realistic numbers for a small Achatina fulica farm. These estimates are based on data collected from Zendric students across Ogun, Lagos, Enugu, and Rivers states.
Small Farm Example: 200 Snails
| Item | Cost / Revenue |
|---|---|
| 200 Breeder Snails (Achatina fulica) | N15,000 |
| Pen Construction (wooden hutch) | N12,000 |
| Feed for 8 months | N14,000 |
| Soil and calcium supplements | N4,000 |
| Miscellaneous | N3,000 |
| Total Investment | N48,000 |
| Survivors (75%): 150 snails at 120g average = 18kg | |
| Revenue at N2,000 per kg | N36,000 |
| Net Profit (Year 1, First Cycle) | -N12,000 (short term loss) |
This might look discouraging, but the picture changes quickly in the second cycle. By then, your breeders will have produced hundreds of hatchlings at zero extra cost, your pen is already built, and your soil is established. Many Zendric students who started with Achatina fulica moved into profit from their second cycle.
The key advantage of Achatina fulica is the volume of offspring. 200 breeders can produce 10,000 or more eggs per year. Even at a conservative 60 percent survival rate to sale, that is 6,000 snails at roughly N300 to N500 each, which adds up to N1,800,000 to N3,000,000 in potential gross revenue.

5 Frequently Asked Questions About Achatina Fulica Snail in Nigeria
FAQ 1: What is Achatina fulica and is it the same as the Giant African Snail?
Achatina fulica is sometimes marketed under the name “Giant African Land Snail,” which is confusing because Achatina achatina is much larger and is also called a Giant African Snail. Achatina fulica is a separate species, originally from East Africa, and is the smallest of the three commonly farmed snails in Nigeria. It grows to about 50 to 200 grams at full maturity, compared to 300 to 500 grams for Achatina achatina. If someone sells you a “Giant African Snail” in Nigeria without specifying the species, always ask to confirm by checking the shell length and weight of mature samples.
FAQ 2: How profitable is Achatina fulica farming in Nigeria compared to other species?
Achatina fulica earns a lower price per kilogram than Achatina achatina or Archachatina marginata in Nigerian markets. However, it compensates through speed and volume. It reaches market size in 6 to 10 months and produces hundreds of eggs per year per breeder. For farmers with limited capital who need cash flow quickly, Achatina fulica can be a good starting point. For farmers targeting hotels, restaurants, or export markets, Achatina achatina remains the more profitable species per kilogram. At Zendric, we often recommend that new farmers study which snail species is best for commercial farming in Nigeria before committing to a species.
FAQ 3: How many eggs does Achatina fulica lay per year in Nigeria?
A healthy Achatina fulica can lay between 100 and 400 eggs per clutch and complete 4 to 8 clutches per year. That means one breeding snail can produce between 400 and 3,200 eggs annually. With a realistic hatch and survival rate of around 60 to 75 percent, you can expect several hundred live juveniles per breeder each year. This is by far the highest egg output of any snail species farmed in Nigeria. Managing this volume well, including preparing enough space, soil, and feed, is critical to turning this advantage into actual profit.
FAQ 4: Can Achatina fulica survive Harmattan in Northern Nigeria?
Achatina fulica can survive Harmattan conditions in Northern Nigeria, but it requires close and consistent care. The dry, dusty air during Harmattan causes snails to aestivate, and if the soil dries out completely, snails can die within a few days. To farm Achatina fulica successfully in states like Kaduna, Kano, or Abuja, you must water your pen soil daily, use shade netting, and mist the pen walls morning and evening. Some Zendric students have built profitable farms in these states by adapting their pen design to reduce moisture loss. The key is not copying Southern Nigeria farm designs without modification.
FAQ 5: Where can I buy genuine Achatina fulica snails to start a farm in Nigeria?
The safest place to buy Achatina fulica breeders is from verified, trained snail farmers, not open market traders. Market traders often mix species, sell sick stock, or misidentify snails entirely. Look for sellers who can show you the mature snail size, shell characteristics, and ideally some hatchlings from the same breeders. Agricultural training centers, snail farmer cooperatives, and specialist instructors are more reliable sources. At Zendric, we connect buyers with trusted snail breeders across Nigeria. Visit our Shop page or Contact Us directly to ask about starter stock available in your area.
