It depends on the species. The most common snail in the hobby for example is the Golden Apple Snail. The female lays its eggs above the water surface at a clutch containing about 200-600 eggs. These eggs will hatch within about 2-3 weeks, depending on temperature an humidity of the air (the air above the water surface should have high humidity)- thus, a glass cover on the tank is essential (water level should be about 5-7.5cm/2-3inch below the glass cover).
1 year until it will be sexual mature, 3 years to grow completely,,, more http://www.nal.usda.gov/afsic/AFSIC_pubs/srb96-05.htm
A mother hermit crab holds them in her shell for a few weeks and when ready let's them out to water
When snails have mated ( they go on backs) it takes about a month for them to lay the eggs. But it takes another month for them to be just visible, so don't chuck them out by accident!
It takes 21 days for ghost shrimp to hatch. On day 18 when the eggs get big and brown move them to another tank.
About 20days
in 20 weeks
1 day
yes they lay it right after mating
There is no such thing as a male snail. Or a female snail for that matter.All snails are hermaphrodites. That means they have both sexual organs. Two snails mating will both sperm and lay the eggs.
It depends what animal it is.
When snails lay eggs they are acting out the natural process of reproduction.

their wings dont have much to do with laying eggs. but only chickens lay eggs without mating
Shortly after the mating season, most insects lay their eggs.
yes
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! :)
After mating.
no
they live on beaches
