A cheetah’s spine is built kind of like a spring. This makes the cheetah’s strides almost like bounds, giving them greater distance. In addition, their rib cage is smaller and more flat to also help breathing and allow more free movement of the legs. Cheetah’s bodies are thin and lanky to make then lighter. Cheetahs also have small and light weight bones to give the cheetah less weight to carry. In addition to small and light weight bones, they have small collarbones to help lengthen the stride for fast acceleration. The hindlimb bones are longer and heavier so the cheetah can take long strides so it can then increase its speed.
