On your mark 🏁 You probably already know that cheetahs are the fastest land mammals on the planet, but do you know why they are quick? Between their flexible spines, long slender legs, and enlarged nostrils that take in extra oxygen, cheetahs are literally built for speed. Agility is a necessity for life on the African savanna, especially when lunch (impalas, springboks, etc.) can be hard to catch. #caturday #cheetahrun #mariokart #sdzsafaripark | San Diego Zoo Safari Park
