Flatworms Cross Swords

By Anupum Pant

Flatworms are hermaphrodites. That is, each individual has both male and female reproductive organs. But to make new baby flatworms they still need to find a mate and once they do, it is an interesting thing that ensues.

The process of mating involves two flatworms fighting, over who’d be the father and who the mother. Or more specifically, the flatworms involve themselves in penis fencing. One tries to stab the other with its “double barrelled inseminater.”. While both the flatworms resist getting stabbed.
