Snails do not make noises when moving from place to place. However, powerful microphones can detect the sound of snails eating. Snails have tiny structures similar to teeth on a tongue that looks like a ribbon. To eat, snails rip their food into pieces.
Most snails eat plants or algae, although some species are carnivores. Snails are found in a variety of locations, including oceans, deserts and ditches. Most snail species live in water. Some snails grow to 15 inches in length and weigh up to 2 pounds. The largest sea snail grows up to 35 inches in length and weighs up to 40 pounds. Snails are often considered to a pest in agriculture and are considered a delicacy in some international cuisines.
