Reproduction Cycle

Snails are hermaphrodites and both partners can be fertalized during mating. Laying eggs in moist soil the life cycle of a snail can be broken down into three stages:

  • Eggs: Eggs can hatch with in 2 to 4 weeks, with dry soil causing eggs to fail
  • Juviniles: when hatched they are born as a snail however their sheel are soft. eating the eggs the will seek calcium to harden the shell typically lasting a few weeeks
  • Adults: typical adults will only live for 2 years with one in captivity lasting up to 10 years
