In Chapter 8 of Nature’s Nether Regions, I describe the wondrous world of hermaphrodite genitalia. One whole continent of that world is the love darts that snails “fire” at one another. These appear to help the shooter to up their chances at fathering the babies of the “victim”, since the dart contains a hormone-like chemical that simulates sperm use. Now, the shapes, sizes, and uses of these darts are very variable: Joris Koene of the VU University in Amsterdam has described several types in this paper. But even to him it came as a surprise when we found that the Everettia snails of Borneo have a type that seems to resemble an actual syringe. We published this new kind of love dart on July 25th, 2013 in PLoS ONE, and a nice write-up appeared in this NBC story.
