If individuals of the same size mate, then bilateral fertilization occurs, but if the size of one of the individuals is larger, then the larger cochlea will be female, since the development of eggs requires high energy costs.

This also causes the young snails to form only sperm cells, and the snails are ready to form eggs only in adulthood.
