Most snails are hermaphrodites. This means that they are both male and female. All hermaphroditic snails can lay eggs. They can "mate" with themselves and thus only one can reproduce in an aquarium or pond. They also breed sexually as often as possible. Most snails lay eggs but some, like the trapdoor snail, give live birth. Trapdoor snails and a few other species of snails (apple, golden inca, four horned, etc.) are not hermaphrodites. They can only reproduce sexually.

They reproduce. Snails are hermaphrodites and when they mate each snail exchanges genetic material with the other snail. After mating each snail will lay eggs.
Yes, some species of snails can reproduce with only one snail present.
Most animals need an animal of the opposite gender, however a snail does not need another snail to reproduce.
Doesn't exist.
almost all of them
a lot because they can reproduce with theresevles whenever they want.
Does it move, reproduce, respond to the environment and use energy? Of course it does, so it is definitely alive.
