What are Land Snails?

Land snails are air-breathing mollusks that possess a retractable muscular foot and a hard, coiled shell into which they can withdraw for protection.

They belong to the subclass Pulmonata, which differentiates them from their marine and freshwater cousins by their adaptation to breathe air.

Their bodies are generally composed of a head, a visceral mass, and a muscular foot, all partially wrapped in a mantle which secretes the shell.

Land snails are hermaphrodites, meaning they have both male and female reproductive organs, which allows them to reproduce without needing a partner. They are known for their slow movement and use of mucus to help navigate their environment.

Types of Land Snails

1)Giant African Snail

The Giant African Snail (Achatina fulica) is one of the largest terrestrial gastropods. Individuals can grow up to 20 cm in length.

They have a light to dark brown shell with vertical stripes of a darker hue, making them easily identifiable.

Unique for their size, these snails are native to Africa but have become invasive in other tropical and subtropical climates, where they damage crops and buildings while also posing health risks due to their ability to carry parasites.

2)White Garden Snail

The White Garden Snail (Theba pisana) is distinctive due to its predominantly white or cream-colored shell, often adorned with spiral bands of brown or gray.

Originating from the Mediterranean region, these snails are smaller, usually measuring up to 3 cm in diameter.

They are unique in their ability to aestivate (a state of dormancy) during hot periods, clinging in groups to stems and leaves to conserve moisture.

3)Mediterranean Green Snail

The Mediterranean Green Snail (Cantareus apertus) is notable for its greenish to yellowish-brown shell and large body size, reaching up to 6 cm in diameter.

It is native to parts of Europe and has been introduced to other regions, including the United States.

Its vibrant color and size make it easy to identify, and it is unique in its preference for higher moisture environments compared to other snails.

4)Garden Snail

The Garden Snail (Cornu aspersum), common in European gardens, has a brownish shell with lighter brown bands that spiral towards the center. It typically grows to about 4 cm in diameter.

This snail is particularly known for its adaptability to various environments and its role in the ecosystem as a decomposer.

Its widespread presence in gardens and fields makes it one of the most recognizable snail species.

5)Roman Snail

The Roman Snail (Helix pomatia), also known as the Burgundy snail, is prized in gastronomy, particularly in French cuisine.

It has a globular shell, which can reach up to 5 cm in diameter, with a light, creamy color and darker brown bands.

Native to Europe, its unique gastronomic value has led to its introduction in other parts of the world, where it is farmed.

6)White Lipped Snail

The White Lipped Snail (Cepaea hortensis) is easily identified by the white band at the opening of its otherwise brown or yellow shell with variable banding.

It is smaller, about 2-3 cm in diameter, and is found across Europe in hedgerows and gardens. Its striking lip color contrast makes it unique among the snail species.

7)Milk Snail

The Milk Snail (Otala lactea) features a large, robust shell that can reach up to 5 cm in diameter, typically colored with shades of white and light brown and marked with darker brown bands.

The Milk Snail is also native to the Mediterranean region, it is known for its ability to withstand dry conditions by sealing its shell with a layer of mucus and retreating into a dormant state during adverse weather.

What Is the Most Common Land Snail?

The most common land snail species can vary by region, but globally, one of the most widespread and recognized species is the garden snail (Cornu aspersum), formerly known as Helix aspersa.

This species is commonly found in many gardens and agricultural areas around the world. It is native to the Mediterranean region but has been introduced to many other parts of the world, often becoming an invasive species.

The garden snail is known for its brownish shell with lighter brown bands and its preference for a variety of vegetation, which often brings it into conflict with gardeners and farmers.

What Type of Land Snail Is Best for a Pet?

When considering land snails as pets, certain species are more popular and easier to care for than others. Here are a few commonly recommended types:

1)Giant African Land Snail (Achatina fulica, Achatina achatina, Archachatina marginata)

  • These snails are known for their large size, which can make them particularly interesting as pets. They can grow up to 10 inches in length.
  • They require a warm and humid environment, with temperatures ideally between 68°F and 77°F (20°C to 25°C).
  • It is important to note that Giant African Land Snails are illegal to keep as pets in some countries, including the United States, due to their potential as invasive species and agricultural pests.

2)Roman Snail (Helix pomatia)

  • Also known as the Burgundy snail, this species is smaller than the Giant African Land Snail but still can grow to a sizeable 4-5 cm in diameter.
  • They are known for their hardy nature and can tolerate cooler and less humid environments compared to tropical snails.

3)Garden Snail (Cornu aspersum)

  • Commonly found in gardens, these snails are relatively easy to care for. They adapt well to various environments but thrive best in moderate conditions.
  • They are smaller than the Roman and Giant African snails, making them less demanding in terms of space.

When Choosing a Snail Species as a Pet, Consider the Following Factors;

  • Legal restrictions: Ensure that the species you are interested in is legal to own in your area.
  • Environment: Can you provide the right temperature and humidity for the species?
  • Space: Larger species will require more space.
  • Care Requirements: Make sure you are able to meet the feeding, housing, and environmental needs of the snail.

Conclusion

Regardless of the species, all snails need a diet rich in calcium for shell development, which can be provided through a variety of leafy greens and commercial calcium supplements.

They also need a moist environment and should be kept in a well-ventilated terrarium with soil deep enough for burrowing. Regular misting will help maintain the necessary humidity.
