BDi composer, Ben Salisbury scores the music to the one-off BBC Natural History programme, Inside The Perfect Predator. Broadcasting on Thursday at 9pm on BBC 1.

Soaring above the people of London is the fastest animal on the planet, the peregrine falcon, on a mission to kill for her chicks.

Off the coast of South Africa the world's largest predatory fish, the great white shark, has just completed a 7000 mile journey and is hungry for seal blubber. On the plains of Africa, the fastest land animal, the cheetah, struggles to provide for her cubs as her enemies move in. And having survived a drought by entering into a state of suspended animation, the prehistoric Nile crocodile is poised to ambush his dinner.

With ground-breaking computer graphics and incredible close-up photography this documentary reveals the inner alchemy that gives these four extraordinary hunters the edge - from the moment they detect their prey through to the vital kill. But who is the Perfect Predator?
