What is it about?
. In this study, these snails did not display physical limitation in mating with a much larger or smaller partner. In the mate choice experiment, we found no evidence for significant preferences for large partners.

Why is it important?
Therefore, mate choice of sperm donor and mechanical constraints are not likely to contribute to the formation of size-assortatively mating pairs in this species, which contributes to understanding about how these processes work in hermaphrodites.
Perspectives
Writing this article was a great pleasure as it has co-authors with whom I have had long standing collaborations. To better understand the importance of body size in the hermaphroditic mating system theory the mating behaviour of Radix auricularia was studied here. More than anything else, and if nothing else, I hope you find this article thought-provoking.
