The notion that mystery snails are asexual has been a long-standing misconception. While these fascinating creatures can thrive in isolation, their reproductive biology tells a different story.
What exactly happens when two mystery snails come together? Do they have a unique courtship ritual, or can they simply switch roles mid-reproduction?
Key Takeaways
- Mystery snails require both male and female individuals to reproduce, dispelling the myth of asexual reproduction.
- They are not hermaphroditic, meaning they do not possess both male and female reproductive organs.
- Mating between two individuals of the same species is necessary to produce fertile nests.
- Female mystery snails can store sperm from a previous mate, but this does not imply asexual reproduction.
- Mystery snails are sexually dimorphic, with distinct male and female individuals that do not change sex.

Can Mystery Snails Reproduce Without a Mate?
Reproducing without a mate is a common myth associated with mystery snails, but pivotal to grasp that this is not the case.
It is essential to understand that mystery snails, like other snail species, require both male and female individuals to reproduce.
This misconception likely stems from the fact that mystery snails can store sperm from a previous mate, allowing them to fertilize eggs for an extended period.
However, this does not mean they can reproduce asexually or without a mate altogether.
In reality, mystery snails are not hermaphroditic, meaning they do not possess both male and female reproductive organs.
Instead, they have distinct sexes, and mating between two individuals of the same species is necessary to produce fertile nests.
How Do Mystery Snails Mate?
Now that we’ve dispelled the myth surrounding mystery snails’ ability to reproduce without a mate, it’s natural to wonder about the intricacies of their mating process.
As we’ve established, mystery snails require both males and females of the same species to produce fertile nests.
The mating process begins when a male and female mystery snail locate each other, often through chemical cues. They then entwine their bodies, with the male depositing a spermatophore, a package of sperm, on the substrate.
The female snail receives the spermatophore and stores the sperm for later use.
After mating, the female snail lays a clutch of eggs, which she fertilizes using the stored sperm. The eggs are then incubated outside the mother’s body, and the developing embryos receive no parental care.
The entire process is a complex and highly coordinated effort, highlighting the importance of both sexes in the reproductive cycle of mystery snails.
Can Mystery Snails Change Gender?
Examining the reproductive biology of mystery snails, it becomes clear that these animals are sexually dimorphic, with distinct male and female individuals.
This means that each snail has a fixed gender, and there is no evidence to suggest that they can change sex.
The misconception that mystery snails are hermaphroditic or asexual likely stems from the fact that they have a complex reproductive system, which can be difficult to understand.
In reality, mystery snails, like all pulmonate snails, have a separate male and female reproductive system, and they require both sexes to produce fertile offspring.
The male reproductive system produces sperm, while the female reproductive system produces eggs. There is no known mechanism by which a mystery snail can switch from one sex to the other.
Any claims suggesting that mystery snails can change gender are unfounded and lack scientific basis.
How to Tell if Mystery Snails Are Mating?
Observing snails in a controlled environment can increase the chances of witnessing mating behavior.
One indicator of mating is the presence of a “love dart” – a calcium carbonate projectile that males use to inject a hormone into the female’s body, increasing the chances of successful fertilization.
Snails will also display a prolonged period of mounting, where the male will climb onto the shell of the female and remain there for several hours. Furthermore, the snails will often entwine their foot and shell, a behavior known as “courtship standing.”
It is essential to note that these behaviors can be subtle and may not always be apparent.
Do You Need 2 Mystery Snails to Breed?
You do need two mystery snails to breed. Specifically, you need one male and one female of the same species.
Males and females exhibit distinct characteristics, making it possible to sex them accurately. Females tend to be larger and have a more rounded shell, while males have a thicker, more elongated shell.
When kept together, a male and female mystery snail will mate, and the female will eventually lay a clutch of eggs. Without a mate, breeding is impossible, and solo individuals will not produce offspring.
How to Tell if a Mystery Snail Is Pregnant?
To determine if a mystery snail is pregnant, look for physical changes and behavioural cues.
A pregnant snail will typically exhibit a more rounded shell, particularly around the belly area, as the eggs develop. The snail may also appear more lethargic or withdrawn, as it prepares for egg-laying.
Furthermore, a pregnant snail may start to burrow or dig more frequently, as it searches for a suitable location to lay its eggs.
It is essential to provide a suitable environment for the snail to lay its eggs, including a deep, moist substrate and a secure hiding place.
Conclusion
Mystery snails are not asexual and require a mate to reproduce.
Notably, a single mating can result in multiple fertile nests, as females can store sperm for extended periods, with some females fertilizing eggs for up to six months after initial mating.
