Garden Snail or White Garden Snail (also known as the Brown Garden Snail)
Phylum: Mollusca, Class: Gastropoda, Order: Stylommatophora, Family: Helicidae, Genus: Cornu, Species: Cornu aspersum · Helicidae (Typical snails) · Gastropod (land snail / univalve), whole spiral shell
Species
Cornu aspersum (formerly Helix aspersa)
Shell Type
Gastropod (land snail / univalve), whole spiral shell
Family
Helicidae (Typical snails)
Size
Approximately 12 mm to 15 mm in width, which is quite small and indicates a juvenile or smaller individual. Adult specimens typically range from 25 to 35 mm in diameter.
Color & Pattern
Mottled brown and tan background with characteristic broken, zigzag yellow or cream-colored stripes and bands. The colors appear natural with a slight matte finish, showing typical earthly tones suited for camouflage among vegetation.
Rarity
Very Common, frequently encountered in gardens and damp terrestrial environments globally.
Habitat
Terrestrial environment, preferring damp areas, gardens, agricultural fields, woodland edges, and urban parks. Found hiding under rocks, leaf litter, logs, or climbing on vegetation.
Geographic Range
Native to the Mediterranean region and Western Europe, but now widely introduced and naturalized across temperate and subtropical regions worldwide, including the Americas, Australia, and parts of Africa.
Description
A small, globose, spirally coiled land snail shell featuring about four to five rapidly increasing whorls. The surface has fine growth lines and a modest texture. The aperture is rounded to oval, and the overall color pattern consists of rich brown shades broken up by attractive, irregular yellowish flecks and banding.
Key Features
Globular depressed spire, rounded aperture with a slightly reflected white lip, and a distinct patterned combination of dark brown bands overlaid with broken yellowish flecks and zigzags.
Collector Value
Low commercial or collector value due to extreme abundance worldwide, though often collected by amateur naturalists and children starting a shell collection.
Condition Notes
Good condition overall, intact spiral structure, minor natural weathering on the apex. Considered a common specimen rather than a high-grade collector piece.
Interesting Facts
Cornu aspersum is a hermaphroditic land snail capable of hibernating during dry or cold periods by sealing its shell with an epiphragm. In some cultures, they are harvested and raised for culinary purposes (escargot).
Ecological Role
Serves as a generalist herbivore feeding on decaying plant matter, seedlings, and agricultural crops. Acts as an important prey item for various birds, small mammals, amphibians, and reptiles, though often treated as an invasive agricultural pest.
Similar Species
Cepaea nemoralis (Grove Snail) and Helix pomatia (Roman Snail). Cepaea nemoralis typically features more distinct, unbroken colored bands and brighter yellows or pinks.
Beach Finding Tips
Not typically found on ocean beaches; instead, look in terrestrial habitats such as damp garden mulch, beneath potted plants, along stone walls, or after a heavy rain shower.
