This episode explores the rich ecosystem of the forest: a terrain covering one third of our planet's total land area. Forest floors and canopies are an excellent hunting ground for some deadly predators and elusive prey. Tropical jungles hide poisonous creatures, while large carnivores ravage northern boreal forests for their meals. Ideally suited for survival in their forest homes, twelve elite animals are distinguished by keen intellect, clever disguises, venomous fangs, and steel-trap jaws. Whether predator or prey, their lethal potential should not be underestimated! Take a trip into treacherous territory, where survival skills are put to the test and see what happens if we get in their way.
