Video: Slo Mo Cheetah and Greyhound
A video showing the cheetah (world’s fastest land animal) in slo mo compared to the world’s fastest dog, the greyhound. The cheetah wins hands-down of course. Although this is not a race. The cheetah is designed for speed not endurance. Perhaps the greyhound has greater endurance. In terms of speed and endurance the most amazing animal is the Mongolian wild ass, which can cover 16 miles at an average of 30 mph. Now that impressive.
The cheetah gets too hot to run flat out further than about 400 metres. It is down to (a) flexible spine (b) huge stride (c) big lungs (d) claws permanently half out (not fully retractable like most cats) (e) floating shoulder blades. The most important is the cheetah’s flexibility.
Read about Cheetah Speed. The top speed is sometimes exaggerated. I think it is 64 mph not the 70 mph often quoted.
