5 Fascinating Facts About the Cheetah

By Mike Unwin

Every schoolchild knows that this greyhound of the cat family is the fastest land animal on the planet – reaching speeds of 120km/h. And no wonder, just look at a cheetah's lithe physique! But this cat also has many other remarkable qualities. What's so special about this cool cat? Let's have a look.

Unlike other large cats, the cheetah’s claws are only semi-retractable. They function more as running spikes, to give the animal traction during high-speed chases, rather than as killing weapons.
A cheetah’s short nose and broad nostrils allow it to breathe while holding the killing bite on its prey’s throat. And they maximize its oxygen intake during and after the exertion of a high-speed chase.
A rare variant of the cheetah, with larger, blotchy spots, was once thought to be a separate species and known as the King cheetah (Acinonyx rex). This coat pattern is simply a mutation from a single recessive gene.
The cheetah is not a big cat of the genus Panthera, like the lion or leopard, but belongs in its own genus Acinonyx. Unlike true big cats, it lacks the vocal structure to produce a roar, and purrs when inhaling rather than – as with true big cats – exhaling.
Cheetahs were kept and trained for hunting during many of the great ancient empires of the Middle East and Asia, including the Egyptians and Persians. Akbar the Great of the Mughal Empire (1556–1605) is reputed to have kept as many as 1,000.
