What is the life expectancy of a snail?
Lifespan. Most species of land snail are annual, others are known to live 2 or 3 years, but some of the larger species may live over 10 years in the wild. For instance, 10-year old individuals of the Roman snail Helix pomatia are probably not uncommon in natural populations.
How smart are snails?
For invertebrates, they live a long time—five to seven years—which means they’re smart. They might sneak into a trap, eat the bait, and then back out, unapprehended. They also excel at reproduction. Each giant African land snail has both male and female parts, so any time one dashing snail meets another, they can mate.
