The Life Cycle of Garden Snails
To better understand how long garden snails can live, it’s important to examine their life cycle.
1. Egg Stage
Garden snails are hermaphrodites, meaning they possess both male and female reproductive systems. After a mating ritual that can last several hours, they lay between 30 to 100 eggs in a single clutch. The eggs are typically buried in moist soil to protect them from predators. This stage lasts about 2 to 4 weeks, depending on temperature and humidity.
2. Juvenile Stage
Upon hatching, garden snail juveniles are roughly the size of a pinhead. This is a vulnerable stage where they must find adequate food and shelter quickly. Their first few months are critical, and many do not survive this phase due to environmental challenges or predation. Juveniles grow and molt several times, acquiring a larger and more developed shell with each growth stage.
3. Adult Stage
Around 6 to 12 months old, garden snails reach sexual maturity. During this time, they exhibit a range of behaviors that provide insight into their lifestyles. Adults can reproduce multiple times throughout their lives, which further ensures the continuation of their species.
Behavior and Adaptations
Understanding the lifespan and health of garden snails also requires looking at their behaviors and adaptations.
