Bedford’s Flatworm: These flatworms are also capable of both sexual and asexual reproduction. They are able to reproduce asexually by cloning themselves. They are also hermaphrodites, which means they are both male and female. Some of the larger aquatic species mate by practicing ritual called penis fencing. Penis fencing is a duel in which one Bedford’s Flatworm tries to impregnate the other by stabbing the opponent with one of its two penises. The loser of the duel has to adopt the female role of developing the eggs, while the winner leaves after impregnating the other.
