The Trapdoor snails are live birth. I watched her have the first three. They are one of the few that do from what I understand. This is a good thing because it keeps the population down. They have a nine month gestation from what I have read and can have up to 15 babies. I just didn't think it would take almost two months to have 12! lol!The cone shaped snail is a malaysian trumpet snail, your snails are so cute but I don't think the trapdoor snail gives live birth I am pretty sure they are egg layers. Assuming I correct here, and don't quote me, then the babies are not trapdoor snails.
