Liz Bonnin meets the animal rebels who will stop at nothing to survive. From cockatoos vandalising houses in Sydney, to crabs who hold nemones hostage to protect themselves, it seems there are no lengths these animals won't go to. Liz sets out to see these animals in action, revealing the science behind their extreme behaviours.
