Every part of the cheetah's body (Acinonyx jubatus) is "designed" for record-breaking performance: the fastest land mammal can accelerate from 0 to 64 km / h in three steps and reach its maximum speed of 112 km / h in just three seconds. It is the only feline to have short, blunt, semi-retractable claws that, like the cleats of soccer shoes, allow excellent grip. His legs are slimmer than those of the other big cats and his bearings, harder, help him make sudden turns at high speed without slipping.

Short sprint. The compact and light structure, the long legs make it, also from the aerodynamic point of view, an ideal model. The specialized limb muscles help it to accelerate very quickly, while the long, muscular tail works as a stabilizer. The cheetah also has wide nostrils that allow an efficient entry of air during the race. His breathing, in running, increases from 60 to 150 breaths per minute: but at this rate he can only run for a little over 500 meters before he is tired.
