before it dies
It depends on the type of snail. Maybe 30 to 20 eggs depends on the tip of the snail. Snails that lay their eggs in aquarium's tend to give birth from 200 to 300 eggs. Snails can only lay 2 at a time. Hermaphroditic snails lay about 80 eggs 6 times a year. Most land snails lay 40 to 60 eggs (according to some authors even 100). Well that's all I know about how many eggs a snail lays a year! :)
depending on the kind of snails you have you will be able to find their eggs. APple snails and mystery snails will lay their eggs in big clusters just above the waterline. If you don't want to have more snails you can just remove the clusters of eggs. All other snails breed like crazy. You will be able to see their eggs on the glass or on ornaments or plants in your aquarium. They are more difficult to control. The eggs will appear to be a clear sort of film.
When snails lay eggs they are acting out the natural process of reproduction.
Typically yes! It's a survival technique. Snails normally lay their eggs in the dark. To help encourage laying you can drape the aquarium with a towel or blanket.

Snails don't give birth. They lay eggs.

pond snails are both girl and boy, so in order to lay eggs, they mate WITH THEIR SELVES and then they lay the eggs in a "jelly like mass" and in about three to four weeks, the eggs hatch
