National Geographic - Planet Carnivore: Great White Sharks

They are the big bosses in their neighbourhoods and they've earned big respect from the other residents but in every case and in every place things can change in a heartbeat. The natural world has a way of challenging even the most majestic creatures and the natural cycle of life and death catches up with every living thing, regardless of their size or their power. Who will rise to their challenges?  Who will be lost to stronger or bigger forces? We're ultimately faced with a disturbing question: what would these complex, sometimes brutal and completely balanced parts of paradise be without their carnivores?
Planet Carnivore: Sharks delves into the cold-water hunting ground of one of the ocean's ultimate predators: the great white shark. In South Africa's False Bay mornings are action-packed and bloody when Haai, a huge, female great white shark, hunts for cape fur seals.  Despite her superb senses and incredible weaponry, Haai is now so big that she can't manoeuvre as well as she used to. Meanwhile, the entire neighbourhood is about to be hit with a mighty blow. Find out how this carnivore chases and chomps its way to the top of the food chain, abiding by one master rule: eat to live.
