The highest mountains on Earth are home to snow leopards, golden eagles, mountain goats, barnacle goslings, and gelada monkeys. Only the toughest of animals can endure the extreme weather and scarce food supplies.
Delving beneath the surface of the Earth's oceans to uncover a world of extraordinary extremes, including crushing depths, stormy coasts, blue deserts, and crowded reefs; how seals fend off sharks; how orcas fight.
In the grasslands, animals endure freezes, fires, floods, and droughts; bull elephants clash in mating battles; cheetahs and gazelles engage in a predator-and-prey dance in the Kenyan savanna.
Jungles comprise the most diverse habitats on Earth in which only the most resilient species triumph; the fiercest jungle species include jaguars, gibbons, orangutans, spectral tarsiers, hummingbirds, and more.
Deserts are getting even hotter, drier and bigger, yet a host of remarkable animals still survive in the harshest of conditions, including cunning hyenas, pint-sized meerkats and sand-dwelling spiders.
The frozen poles are home to the planet's ultimate survivalists, including polar bears, penguins and Arctic wolves; their world is changing fast, and their resilience will be tested.
