Apex Predators vs Prey | Herbivores and Carnivores | FULL EPISODE | Wildlife Documentary. Inside the Ngorongoro Crater of Tanzania, 25,000 wildebeest, zebra and buffalo live their whole lives inside a ring of rock they can never leave, and the lions and hyenas that hunt them can never leave either. Across four hours of chained chapters, apex predators and their prey face each other behind the greatest walls in nature, where the fortress that protects is also the fortress that charges the toll. Through cinematic footage and educational storytelling, the first hour follows two walled kingdoms. In the crater, a hyena charges the gap between a wildebeest mother and her calf, a male lion holds a carcass against a whole clan, and eight hyena clans tracked for thirty years turn out to hunt most of their own meals. With nowhere to be exiled, old age gathers in plain sight: bull elephants with tusks brushing the grass, lone buffalo dagga boys, and two former kings with worn teeth who spend three days hunting one old bull before a younger pride takes the prize. Then the story crosses to Antarctica, where emperor penguins walk willingly into the winter, past a leopard seal at the door, to fast for 115 days in a living wall of bodies, until their chicks must leap from a 50 foot ice cliff into the sea. 0:00 A Paradise With No Way Out 0:40 Ngorongoro: the Fortress in the Fog 2:50 Hyena vs Wildebeest Mother 4:23 How the Wall Was Built 6:45 A Kingdom That Never Migrates 8:20 The Hyena Clans: 30 Years of Records 9:13 Lions vs Hyenas at the Carcass 12:13 The Scavenger That Hunts 12:52 Old Age Has Nowhere to Hide 13:40 Bull Elephants and Dagga Boys 16:33 Hyenas vs Zebra: the Daily Roll Call 19:06 Reading Time in the Mouth of a Lion 21:27 Kings Do Not Die Here, They Wear Down 22:10 Six Sets of Teeth: the Elephant Clock 24:00 Two Old Kings on the Margin 25:34 Old Lions vs Old Buffalo: the Final 27:34 A Young Pride Takes the Prize 29:49 The Plague of 1962 and the Founders 33:22 Antarctica: a Wall of Ice 35:38 Emperor Penguins vs Leopard Seal 37:29 The March Into the Winter Night 39:22 115 Days of Fasting 40:27 The Storm and the Living Wall 43:15 Born on the Feet of a Father 45:57 Giant Petrel vs the Creche 50:56 The 50 Foot Cliff at Atka Bay 55:03 Halley Bay: the Door Slams Shut 56:53 Two Walls, Two Clocks 59:00 Apex Predators vs Prey: Lions vs Buffalo 1:59:00 Hyenas vs Lions: Rivals of the Savannah 2:59:00 Predators of the African Plains Epic Moments in This Documentary: A wildebeest mother wheeling on a hyena to save her calf in the fog A male lion stepping toward an arc of hyenas closing on his carcass A whole hyena clan fleeing as the pride arrives at the carcass Hyenas pushing a zebra herd to read which stride is slowing Old bull elephants feeding in the Lerai forest with tusks to the ground Two old lions baiting and flanking a buffalo deep in the mud A young pride arriving and the old kings backing away without a fight An emperor penguin escaping a leopard seal in a burst of bubbles Thousands of males packed into a huddle as a winter storm hits A giant petrel diving at a creche of chicks on the ice Seven hundred chicks leaping from a 50 foot ice cliff at Atka Bay Lions and hyenas against buffalo and zebra on the savannah in the chained chapters Behind the drama is a system. Walls charge a toll in both directions. Behind the stone wall of Ngorongoro, prey never migrate and predators never leave, so the fallen stay to grow old: by about age ten most wild lions carry damaged teeth, elephants wear through their sixth and final set of molars by about 65, and after a plague of biting flies in 1962 cut the crater lions to about a dozen, every lion there today descends from 15 founders, with only one outside male breeding in 48 years. Behind the ice wall of Antarctica, a male emperor penguin burns 40 to 45 percent of his body through 115 days of fasting, and the huddle cuts the energy use of each bird by about a quarter. The emperor penguin is Near Threatened, and when the sea ice fails, as at Halley Bay from 2016, whole colonies lose their chicks.
