you can check their ages by counting the cracks on its shell.

The bigger the snail is the older it is, also as snails age they move slower. Cracks on snails shell happen natrually, if they are dropped or something heavy is dropped on them, a crack can form. A young snail might have more cracks then a very old snail.
Fifteen (15) years is about the maximum life expectancy of garden snails (Gastropoda class). The age may be determined by counting permanent snail rings of growth.
you can tell by the colour of the shell and the size of the snail
You can tell how old it is because of how many stripes there are on its shell
You count how many rings there are on their shell. So if there is two rings it is two years old. The more rings there are the older your snail is.
There's no legal age to eat snails. But they may be "chewy", so it is best to have teeth.
