Steve Backshall's journey is almost over, he only needs two more animals to complete his Deadly 60 list. It is a tough choice and Steve is in the rainforests of Brazil on the search for the final contenders. The place is teeming with wildlife, not to mention some seriously large spiders, but Steve is after a monster tarantula for his list. Deep in the jungle at night, Steve and the team witness one of the most amazing spectacles of the series as they encounter a colony of army ants on the move.
