Bondar examines the sex lives of our animal cousins, which 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?
