Chris Packham delves beneath the skin of the big cats to explore what makes them such good hunters, and he reveals that it is not all about brawn. New scientific research shows how subtle adaptations in their anatomy and physiology contribute to the success of all stages of a big cat hunt: the stalk, the capture, and the kill. Leg hairs help the leopard to stalk and intricate muscle fibres drive the snow leopard to capture its prey. For the jaguar, jaw muscles and whiskers combine to give it a precision bite that can take down a caiman, and an enlarged area of the lioness's brain gives it the edge over all their big cat cousins.
