Water snails typically lay eggs in the warmer months of the year, as the eggs require a stable temperature to develop. Depending on the species, water snails may lay eggs in clusters or individually, often attaching them to underwater plants or other structures.
When snails lay eggs they are acting out the natural process of reproduction.
every day they get pretty busy
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! :)
yes
they live on beaches
Japanese trapdoor snails give birth to live young.
Yes, Mosquitos lay there eggs in water and there larva live in water, Fish need water to survive and pond snails can also thrive in water.
they lay about 80 eggs up to 6 times a year
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
Snails don't give birth. They lay eggs.
