Some species have sex differentiation, so every individual is either male or female. The life expectancy of snails in the wild is about 3 to 7 years, but in captivity, they can live up to 10-15 years or even more. Snail shell is made of calcium carbonate and keeps growing as long as the snail grows. They keep adding more calcium carbonate to the edge until the snail reaches adult size.
Land snails are terrestrial gastropod mollusks that have shells (those without shells are known as slugs). In reality however, it is not always easy to say which species are terrestrial, because some are more or less amphibious between land and freshwater, and others are relatively amphibious between land and saltwater.The majority of land snails are pulmonates, i.e. they have a lung and breathe air.he lifespan of land snails varies from species to species. In the wild, Achatinidae snails live around 5 to 7 years and Helix snails live about 2 to 3 years. Many deaths are due to predators or parasites. In captivity, the lifespan of snails is much longer than in the wild, ranging from 10 to 15 years for many species.
