The cheetah is well designed for optimum speed. Its lightweight skeleton includes an unusually supple backbone that can coil and uncoil like a spring. The cheetah is also endowed with a deep chest, ample lungs, a strong heart, a tail that provides balance, and large nasal passages that allow for rapid breathing—all of which contribute toward this animal’s unmatched swiftness.
There are approximately 244 bones in a cheetah's skeleton as it is considered a lesser cat and cats have approximately 244 bones. The cheetah is considered a lesser cat rather than a big cat, such as tigers or jaguars, because it does not have a floating Hyoid bone in its neck and it cannot roar.
