Cheetahs have always been my favorite. It’s not that they’re the fastest land animal that fascinates me, but how. Dogs are so funny to watch run because they’re so goofy, but even the fastest dogs get going maybe 40 miles an hour. They spend a lot of time off the ground in their stride. And if you’re not in contact with the ground, you’re slowing down. Cheetahs keep their strides very low to the ground and spend little time in the air. Additionally, their long, muscular, flexible spine allows them to treat it kind of like a leaf spring. And the long tails are gorgeous.
