We travel downunder to meet one of Australia’s most unusual creatures: Ornithorhynchus anatinus, better know as the Platypus. Few animals have caused such debate as our duckbilled friend, for nearly a century leading scientists across Europe (maybe they should travel a bit closer to their subject) debated exactly what this paradoxical animal was – mammal, lizard, something entirely new? What are the eggs all about, and where are the nipples? And don’t get us started on the penis! The Platypus is one very strange animal indeed. We explore the folklore, tell the history, look at the science of how we came to understand Ornithorhynchus anatinus. Along the way there are epic arguments and a secret WW2 mission, finally we top it off with a rap written and performed by Anton!
