From the jungle's big cats to the garden spider, these creatures have learnt to survive by outrunning or outwitting their prey and by using some of nature's cleverest and most deadly tools. Some have developed the speed and dexterity for the CHASE; a golden eagle swoops in for the kill at breakneck speed, just as a penguin dives deep below the surface, tucking in its feathers for minimum resistance against the water.

Cats are well adapted for hunting in different environments and have a large armoury of tools to execute the perfect kill. Stalking, jumping, pouncing or running, lone hunters or team players, cats are built for the kill.

The Formosan Black Bear, the largest carnivore in Taiwan, is a subspecies of the Asiatic Black Bear (Ursus thibetanus) found throughout Asia. They are called "Moon Bear" in China and they are currently listed as a vulnerable by the IUCN, the International Union for Conservation of Nature. From the aspects of ecology or culture, they bring special meaning to this island.

Built for the Kill - Bird of Prey takes a look at some of the most graceful killers in the air. Precisely designed hunters, perfect stalkers and masters of aerial combat, birds of prey, also known as raptors, are the killing machines of the skies. Raptors like the peregrine falcon, goshawk and the harpy eagle, use speed, persistence and sheer strength to claim their quarry from the ground or in the air. Some, like the spotted owl, have hearing supersensitive to the smallest sounds and eyesight built to see in the dark. All raptors have the tools for killing, including beaks for inflicting fatal blows and dismembering their victim and feet that crush and grasp their prey. Each is built for the kill!

Look below the surface at the ocean's most terrifying predators at their predatory traits: super-sensitive smell, sight, teeth and powerful jaws, all built for the kill.

An army of nature's smallest critters. Enter a world of predator & prey,where sophisticated weapons and unrivalled cunning all play a part.

Nature's most improbable predators – they come in all disguises, and few would suspect they're primed for killing. Enter a world where even the most innocent of plants possess killer traps.

It is a simple piece of equipment - a biological hinge - that changed the course of evolution forever. It's no wonder the term "Jaws" has become synonymous with death. This programme examines the spectacular armory that the most infamous of predators wear

Prey animals may find safety in numbers, but many of the world's most cunning predators know another kind of math: numbers kill. This programme takes a look at the way animals hunt en mass - from simple feeding frenzies to carefully choreographed violence

Many predators use speed to survive in the inevitable game of catch-me-if-you-can played out everyday in the wild. Speed increases the odds of winning.

Experience the menace of killer reptiles. From toothy alligators to gravity defying geckoes, these are real life monsters. They have been around for 200 million years, and once reigned supreme as the dinosaurs. Their ancestors were amphibious creatures that are still around today; the frogs, toads and salamanders are almost all carnivorous. From them evolved creatures like the crocodiles and alligators who have outlived the dinosaurs. Today reptiles show many extremes of adaptation. Snakes with deadly venom and crushing coils; poisonous lizards like the gila monster and Komodo dragon; chameleons with their deadly tongues; turtles with monstrous crushing jaws. Far from being primitive slimy critters, amphibians and reptiles have survived because they're BUILT FOR THE KILL, and they're here to stay.

The world of flying insects is a colourful and varied one. From the deceptive cannibal praying mantis to horrific dragonfly larvae impaling unsuspecting fish on spring-loaded, dagger-like mouthparts. These are alien creatures, 'Built for the Kill'. This is a film about gore; as blowfly maggots in their thousands, eat their way through rotting festering corpses and botflies live within horse's stomachs to feast on them alive and from within. For most flying insects, it's the larvae that are killers, be they parasitic or hunters. Harmless hoverflies mimic wasps as adults but their larvae suck the bodies of aphids dry, killing 400 in their lifetime. Adult hornets are vegetarians, but they still need to kill to sustain the voracious appetites of their grubs in the nursery. And discover the world's deadliest killer; responsible for the deaths of more than half the people that have ever lived; the mosquito is a creature to be feared... All these deadly insects have one thing in common; their thirst for flesh is driven by their ability to fly, and they're Built for the Kill.

Some of them live among us, on our hearths and couches, but deep in their genes lays a killing communion with their cousins. The canines are among the oldest surviving carnivores on earth, honing their killing perfection over millions of year. While the c

Wind whips across the ice-clad landscapes. Freezing hail and sleet scream across the snow swept plains and mountain tops. While life huddles into hidden burrows for warmth and safety, killers of the cold lurk. To hunt and kill during the menacing grip of winter demands extreme adaptations. Formidable Polar Bears, talon-charged eagles and wily coyotes are among the predators that haunt these hostile climes.
