Hey sis! Snails age is determined by the number of rings in their shell, just like you date a tree by it's rings. I've not looked to see how long they can live, but I found another 7 year old tonight, plus a couple of younger ones. It's been raining here a lot, and they come out in the forest after the rain. They are really very pretty in a snaily way. Take care my sweet sis and have a wonderful evening!🤗🤗💕🌸
