Meet TV presenter and naturalist Chris Packham who films a host of animals that use deceptive tactics to find food. 

New science reveals that some trick their prey, like the manipulative mantis that looks like a flower, and killer whales that set traps using sound.

Others cheat each other - sea otters demand ransoms after kidnapping each other's pups. 

And in their parks, grey squirrels are at war - stealing raids can only be foiled by a devious...    

sleight of hand.

Some fool other species for food - meet the drongo, an African bird running a false protection racket, and monkeys who steal valuables from humans and then barter for their return. 

These animal liars, cheats and hustlers really will stop at nothing to get a meal.
