Steve analyses three hunts from the scaly world of lizards. A Jackson's chameleon uses its enormous tongue to hunt down a praying mantis. The world's largest living lizard, the Komodo dragon, uses a toxic bite to try and bring down a water buffalo ten times its size. And Steve goes into the upside-down world of the tokay gecko, which uses its incredibly sticky feet to defy gravity in its hunt for moths. Three predators. Three prey. Who will emerge victorious?
