Moment of Impact: Hunters and Herds  

The predators and prey of the world's grasslands are examined. Including: the wildebeest of Africa's Serengeti, which risk becoming lion meals unless they maintain a 50-yard safety zone from the big cats; the ground squirrels of California's grasslands, which flick their tails at rattlesnakes in order to fool the reptiles' heat-sensing pits so they perceive them as larger than they really are. Also: the giraffe; the elephant.
