The Garden Snail (Cornu aspersum, formerly Helix aspersa) is one of the most widely recognised terrestrial molluscs. Native to Europe, it is now common in temperate regions worldwide. The shell is coiled and globular, varying in colour from light brown to yellowish with dark spiral bands. Its soft body is greyish. While most individuals are smaller, under ideal conditions these snails can grow up to 4 cm in diameter.

Location:
Moist, sheltered environments such as gardens, hedgerows, woodlands, and grasslands. Now found widely outside its native range due to human introduction.

Average Size:
Up to 40 mm (4 cm) in shell diameter.

Family:
Helicidae (Typical Snails)

Species:
Cornu aspersum

Ecological Role:
A decomposer and herbivore, feeding on leaves, flowers, and decaying plant material. It also serves as prey for birds, beetles, and small mammals. Culturally significant as a food source in many regions, particularly in French cuisine (escargot).

Movement and Sensory Features:
The Garden Snail secretes mucus that allows it to glide smoothly across surfaces, leaving behind a slimy trail which reduces friction. It has two pairs of tentacles: the longer pair bear the eyes at their tips for vision, while the shorter pair are used for touch and smell to navigate its surroundings.

Conservation Status:
Widespread and abundant. Considered invasive in some non-native regions due to its adaptability and impact on agriculture and native flora.

Collection Date:
Collected on 12/07/1922 in St Ives.
