    Because flatworms are hermaphroditic, capable of being the male or female during sexual reproduction, the first rule in mating for any pair of these lovers is to decide who plays what role. To settle it, they engage in an activity that has been described as "penis fencing," which is pretty much what it sounds like. Using their penises as swords, the two flatworms battle it out to see who can inseminate the other first, which is accomplished by stabbing the other in the underside. The loser ends up being the mother.

    These battles are hardly innocent foreplay. Flatworms will often gouge gaping holes in one another, and the fight can last for up to an hour. Not only does the winner get to gloat, but it also gets to swim off without any further biological responsibility in producing the offspring.

    So do you want to wrestle? Or penis fence? The good thing is neither will be left without any further biological responsibility.

    I'm more concerned with who will be leaving with "gaping holes" ?

    I have my own kayak. I guess that makes me the wrestle-for-top creature of the river.

    My favorite are the sea cucumbers who can turn themselves inside out when threatened. Imagine if people could do that...icon_surprised.gif
