11. "The Hunters and Hunted"
Broadcast 27 March 1979, this programme surveys mammal herbivores and their predators. The herbivores began to populate the forests when the dinosaurs disappeared, and many took to gathering food at night. To prepare for winter, some store it in vast quantities, some hibernate and others make do as best they can. However, the carnivores joined them, and when a dying climate triggered the spread of grass, they followed their prey out on to the plains. Grass is not easily digestible and most animals that eat it have to regurgitate it and chew the cud. Out in the open, the leaf-eaters had to develop means of protection. A few species turned into burrowers: examples include the blind mole-rat, which is completely underground, and the prairie dog, which isn't. The capybara ? the largest rodent ? spends much of its time in the water. Those that evolved long legs and hooves, such as the zebra and impala, seek safety in speed, while larger creatures, such as the rhinoceros, rely on their armoured hides. The elephant is the world?s largest land animal and is virtually invulnerable. Cheetahs and lions are attracted by those that herd in large numbers, like wildebeest. The cheetah uses its considerable speed while the heavier lion is a social predator, mostly using co-operation and stealth to capture its victims, and its methods are explored in detail. Meanwhile, a pack hunter, such as the hyena, has immense stamina and will eventually wear down its quarry, easing the kill.
