You can't.
They are all the same gender.
A snail is both female and male. They are hermaphrodites.
If you are keeping pet snails that have similar markings and cannot tell them apart, use different coloured paints (not water-based) or nail varnish to put a small dot of colour on the shell to help with identification. If the question meant "how do you tell male and female snails apart?", then the answer is that there are no male or female snails. Snails are hermaphrodites (have characteristics of both sexes) and so any two snails can reproduce.
It doesn't matter because with snails, both male and female can have babies. They're reproductive organs are the same. :) As for your original question, I can't help you with that.
Some snails have a shell that you can see through. The male has a white organ that the females don't have.

See image link below. See differences at applesnail.net -> anatomy -> reproductive system section. Some few species of snails are bisexual, being both masculine and feminine.
you cant really because snails are hermaphrodites; they have both male and female organs.:)
You simply do not. There are no such thing as male and female snails.All snails are hermaphrodites.That means all snails have both male and female reproductive organs. They still need to mate with another snail in order to produce and lay eggs.Some amateur gardener groups will try to say that snails with a brown-striped shell are girls whereas white stripes are boys. This is false - they are actually two completely different species. Therefore "snail breeders" breeding these two are creating a hybrid or mixed-species.So the answer to your question is that you can not tell if a snail is male or female, because snails do not have male/female genders. They are all hermaphrodites.
snails are both males and females because they have a female uterus and oviduct and ovaries and they also have male testis and spermduct. That is the only thing i can really tell you. We will prolly never know exactly why they are this way. This is the way that God made them and we should just leave it at that. Snails have both male and female organs so they are able to reproduce without a mate. This may seem like a pointless answer but there is a difference in reproducing and creating genetic diversity. Genetic diversity is achieved when two snails mate together. Now how which one "plays" male and which one is female when they do breed is quite thought provoking.
I have heard that a male water snail will have a tube like object popping out of his shell while a female does not. Im just taking a guess here, but i think it should help.
Feeder fish, How do you tell male from female of the?
You can tell if someone is male or female by their reproductive parts.
