‘Penis fencing’ in Tulamben? It’s not so strange in the context of flatworms, and specifically the Pseudobiceros genus – notorious ‘penis fencers’!
The point of this ‘game’ is for two flatworms battling to NOT be inseminated with sperm…and be ‘burdened’ with motherhood! It’s actually a battle you wouldn’t want to lose, because the the one ‘fenced’ will be physically damaged in the process and as a result be weaker. Their body is flat (obviously!), except for two extendable dagger-like stylets on the front – their fencing ‘equipment’. No mate? No problem! They will simply ‘fence’ themselves because this species have BOTH sex organs (hermaphroditic). Honestly – these strange and fascinating facts about underwater creatures are the reasons why we make scuba diving our lifestyle as PADI Pro Divers at Bali Dream Divers Tulamben!
