Adam Hart investigates the fastest land animal in the world – the cheetah! Built for high-speed chases, these spotted cats are slender, with semi-retractable claws for good grip and a flexible spine plus a long tail for balance and manoeuvrability. Cheetahs rely on speed over brute strength when hunting – and can make tight, quick turns to shift course in fast pursuit of their prey. But with shrinking populations cheetahs are classified as vulnerable – so what’s being done in terms of conservation and are these projects having any success? Adam hears how cheetahs differ from lions and leopards and learns about their relationships with other predators. He looks at their unique adaptions and behaviours, as well as the different approaches that conservationists are undertaking to try and reverse the population decline. And we also hear about the re-introduction of cheetahs to India.
