NATURE: Moment of Impact “Hunters and Herds”

Take a unique look at the amazing biomechanics of animal predators and prey. Wednesday at 8 p.m. on PBS-HD 6.

They are the scenes of some of the largest concentrations of predators and prey on the planet — the vast tracts of grassland and savanna found on every continent but Antarctica. Yet survival in this open, horizontal world is far from easy, with few places to hide, a scarcity of vegetation, drought, fire and the threat of attack by some of the world’s fastest and most powerful hunters.

From Africa’s Serengeti to California’s grasslands, some of nature’s most dramatic moments are caught, examined and “fractured” into their unique parts … within creatures great and small … to reveal the amazing abilities that give each animal the instinct, intelligence and brute prowess to survive. From elaborate impact sequences that spin around animals caught in a “frozen moment” to animations that go inside their bodies — a unique view of animals’ amazing biomechanics is revealed.

NATURE: Moment of Impact “Hunters and Herds,” Wednesday at 8 p.m. on PBS-HD6.
