Predators are animals that kill other animals for food, their prey.
The attacking predator and defending prey each make life-and-death decisions.
Finding the right strategy is a complex task.
Predators have evolved a range of physical and behavioral adaptations to catch their target.
If this lioness attacks the zebra from behind, the zebra can kick it off.
But from the side, she can wrestle the zebra to the ground.
Hunting alone, she will have a 30% chance of success, but by joining forces this can double to 60%.
For some, it's all in the senses. The python tracks its victims with smell, sight and heat sensing.
For others it's speed.
Cheetahs use camouflage to stalk their prey to within close range, before bursting into an intense high-speed chase.
The polar bear plays a waiting game. Its prey, the ringed seal, has to surface to breathe.
The fat from one seal will keep it going for a week, so the bear's strategy is to find a breathing hole, and wait.
Whatever the technique, predators must always balance the chance of catching their prey with the energy used in doing so.
But prey also adapt to outwit their predators.
The seal's whiskers are extremely sensitive to sound vibrations, so they can detect the slightest movement of the polar bear's feet.
Alarm calls warn of approaching danger and camouflage and patterns can be crucial.
The zebra's stripes hide individuals when they huddle together.
The predator-prey dynamic ties two species together in a close and complex relationship.
As each evolves adaptations to outwit the other, they co-evolve together in a constant battle for survival.
