Fun facts about the Snail
A snail's shell grows with it throughout its entire life, adding new rings of calcium carbonate as the animal enlarges. Snails move on a single muscular foot, secreting mucus to reduce friction — the same slime that lets them crawl upside-down on glass. Some garden snails can sleep for up to three years during drought. The giant African snail is the world's largest land snail, reaching 38 cm in length.
