The carnivorous snails have tongues that are covered with thousands of tiny teeth to tear apart food. The gastropod fossils from Jacksboro, TX shown below are from the Pennsylvanian, Finis formation, and these gastropods lived about 300 million years ago.
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.
