I own a ramshead snail. And have had it for about 3 months. I cleaned a smaller tank today and transplanted some live plants from that tank. After moving the plants I noticed a small snail in the tank. It isnt a ramshorn snail is has a longer cone shaped shell. Where did this snail come from? Also I did find a smaller Ramshorn! Are snails A-sexual??? Thanks
 
Yes most snails are a-sexual. The small cone shaped snail is a malysian trumpet snail....and probably came with your plants. And I do believe that ramshorns are a-sexual as well.

Though not all snails are a-sexual...apple snails are not. There needs to be a male and female present to do the deed.
 
Absolutely not! I have never heard of an asexual snail and doubt seriously if such a thing exists. Where on earth did that myth come from?

Common ramshorn and commpn pond snails are hermaphroditic - they have both male and female organs and can function as either sex, but it takes two to tango - one functional male and one functional female. They can also store fertilized eggs or sperm for future use, so a previously fertilized snail can produce viable eggs over an extended period, similar to livebearing fish. But these snails have both sexes, not no sex.

MTS are parthenogenic females, and can produce viable offspring without fertilizarion by a male. But they are anatomically female, not asexual.

Apple snails are either males or females, not both simutaneously, but also always one or the other, not asexual.
 
RTR, I believe the myth was started by a simple confusion of terms, but Im not possitive on that

Can you please elaborate on this? what is the difference between a female who can fertilize herself, and an organism with no sex, capable of reproduction with itself.

MTS are all female...Also they have live births... Quite interesting...
