Adventurer/survivalist Bear Grylls hosts and narrates this six-part docuseries, which draws attention to the volatility of Mother Nature and the resilient animals that survive Earth's most extreme habitats. Each episode characterizes one of the planet's roughest environments
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, scarce food supplies and limited oxygen on these peaks.
Jungles comprise the most diverse habitats on Earth in which only the most resilient species triumph; the fiercest jungle species include jaguars, caimans, gibbons, orangutans, spectral tarsiers, hummingbirds, and parasites.
The frozen poles are home to the planet's ultimate survivalists, including polar bears, penguins and Arctic wolves; their world is changing fast -- breaking apart under their feet -- and their resilience will be tested beyond the extreme.
