Garden snail (Helix aspersa) inside a glass. Snails have a single foot which they use for locomotion. Movement is created by successive contractions of the muscles inside the foot. The surface underneath the foot is known as the sole. It glides over a thin film of mucous which reduces friction. The film of mucous also improves suction and enables the snail to climb vertical surfaces | |
