Helix pomatia lives in the wild have a typical lifespan of five years, while those that are held in captivity can live longer than ten years. Egg deposition affects lifespan because it causes significant weight loss. Snails that inhabit densely populated areas also suffer from higher mortality rates. Nematodes, trematodes, fungi, and other parasite are capable of infecting dense snail populations, causing high mortality.
Status: wild: 10+ (high) years.
