Thought about sex today? Of course you have! It's about the most natural thing any animal can do. But have you ever wondered how human sex compares to that of other beasts? It's far from merely inserting part A into slot B. The sex lives of our animal cousins are fiendishly difficult, infinitely varied and often violent. They involve razor-sharp penises, murderous cannibals and chemical warfare in an epic battle between the sexes. Like us, animals must first find the perfect partner. You think we have it tough? Try having to do it while being hunted down by predators, against a backdrop of unpredictable or life-threatening conditions. Then, sperm and egg must successfully meet. Can you imagine doing this when your partner is intent on killing you or when other disgruntled singles are determined to throw you off your game? The next task is to ensure that the resultant offspring reach sexual maturity in order to keep the cycle going. The myriad ways in which this is accomplished is ingenious. Join Carin Bondar on a fascinating journey from puberty to old age across the entire animal kingdom - it will forever change your idle daydreams about the nature of sex.
