Cornu aspersum was formerly known as Helix aspersa, (Müller, 1774) The snail's muscular foot contracts to move the animal, and secretes mucus to facilitate locomotion by reducing friction against the substrate. It moves at a top speed of 1.3 centimetres per second (47 metres per hour) and has a strong homing instinct, readily returning to a regular hibernation site. Like other Pulmonata, it is a hermaphrodite, producing both male and female gametes. During a mating session of several hours, two snails exchange sperm and after a few days each will dig a nest in the soil and deposit fertilised eggs in it. The young emerge from the eggs after about two weeks, and take one to two years to reach maturity.
