Default Can you tell a male from a female apple/mystery snail?

Any physical sexual dimorphisms?

I have two of them.
I saw one insert a tenticle into the other but not sure if the other is a female.

thanks.

yeah, I saw that one but nothing on the outside of their bodies that let me know their sex. I guess you can't tell by looking.

Yes....they are hermaphrodites. This goes for any snail or slug, and even earthworms. What you saw was an exchange of a sperm packet to another.

These guys are technically not hermaphrodites.. They're either male or female not both... however a male can switch to be a female over time and I guess visa versa.

I have to tell you that it is a pain in the A$$ waiting for them to open up enough for you to see though.

Smile Re: Can you tell a male from a female apple/mystery snail?

This will show you pics of applesnail reproduction. It's from applesnail.net

Is that what you saw your snails doing? If so than you have a male and a female. They will lay clutches when conditions are right. I suggest you make sure the entire top of the tank is covered because the female can "fall" out of the tank sometimes when she's depositing clutches. Also lower the water in the tank a bit so they have room to get their entire body out of the water.

If you read the first line on the above linked to page it reads:
"The apple snail has separated sexes (dioecious) and is NOT a hermaphroditic snail."
It also goes on to say:
"A sex change from male to female (proandry) has been described for some Pila and Pomacea apple snails. In case of Pila snails, the male needs a preparatory aestivation period to become a female, while the Pomacea snails can change sex at all times (at least in certain species). During this sex change, the testis change in colour and decrease in size. The frequency at which this sex change occurs is not certain and not much literature is available about this subject."

Just because you see two snails "mating" does not mean that you have a male and a female. It only tells you for sure that the one on top is a male. Male apple snails are known for trying to mate with any and every other snail in the tank even if it's another male. So don't rule out the chance that the snail on the bottom is not a male snail. Because you just will never know for sure unless you see her laying eggs or find his/her sex the way it says to in those links.
