The dry season is the toughest time of the year in the Amazon rainforest. As the river levels drop, predator and prey are forced even closer together. Giant river otters, found nowhere else on earth, must teach their young pups to swim and fish if they are to survive the rest of the year; will they grow big enough in time? Capybara babies are bite-sized for an array of fierce jungle predators. This episode reveals the survival secret of one of the oldest species living on the waterways; how one of the smallest and most deadly Amazon animals adapts to the changing seasons; how tiny turtles can survive terrifying flash flooding; and how one tree can be the difference between life and death for a huge number of animals in the dry season. In the Amazon jungle, conditions can switch from cracked earth to submerged trees in an instant, and the species that live here must be resourceful to survive.
