Steve's journey has reached Peru in South America. Dominated by the towering Andes mountain range, it's a challenging environment where animals survive by being deadly, and Steve is on their trail. In the mountain's shadow Steve searches cactus-strewn scrubland for a rare barnett's lancehead. This heat-sensing ambush predator is a venomous viper with a fearsome reputation. Trekking into the mountains Steve is on a stakeout to film the largest bird of prey on the planet, the lord of mountain skies, the Andean condor. Next, the team discover that their rustic accommodation has been invaded by eight-legged horrors, tarantulas. Using a night-vision camera Steve watches these assassins hunt their insect victims. Finally, Steve tracks down an incredible insect that turns the tables on tarantulas, it's one of the largest wasps in the world, and preys on these huge arachnids.
