The life cycle of any animal is the period involving the succession of one generation to the next through reproduction. The nest is about 1 to 1.5 inches deep. While some species live for five years, the species of snails living in captivity can survive for as long as 25 years. Diet varies over the life cycle: in hatchling snails, oophagy during the hatching period inside the hollow in which the clutch was laid has been reported, significantly enhancing growth and survivorship (Desbuquois and Madec, 1998); after a few days, this behaviour is lost. Slugs are legless, unsegmented and boneless. Snails and slugs have similar life cycles. Life History of the snail. Both garden pests rely on their muscular foot to move and the secretion of mucous or slime on which they glide.
