In episode two Liz Bonnin meets the animals doing whatever it takes to find food.
From coconut crabs who seem intent on a stealing spree, to tigers deceiving their prey and chimpanzees waging war on their neighbours, finding their next meal can drive many animals to some seemingly extreme behaviour.
Liz sets out to discover the science behind these tactics, joining experts making new discoveries around the world. She sees macaques using psychology to pull off a theft, a spider conning its prey with a chemical disguise, and the wedge-billed hummingbird stealing nectar from under the beaks of its rivals.
When it comes to finding food, Liz reveals that what seems like outrageous behaviour is actually an ingenious way to get ahead.
