Big predatory animals capture our imagination like few others, yet the deadly denizens of the deep sea remain shrouded in mystery. It is these predators that evoke primordial feelings of awe and terror. How and when did they evolve? What makes them such deadly predators? What does their future hold? And just who is the ultimate predator of all time? Despite being at the top of food chains for over half a billion years, predators are also very vulnerable. Who takes the top spot has changed dramatically through the ages, and not always in predictable ways. What evolutionary novelties as well as mass extinctions have overturned who gets to be the biggest and baddest? Join three Museum Victoria scientists to hear an exciting evolutionary tale which will answer all of these questions (and more) and challenge some of your ideas of life's big predators and their place in nature.
