Cheetahs have evolved many adaptations that enhance their ability to sprint. Their legs are proportionally longer than those of other big cats; an elongated spine increases stride length at high speeds; they have unretractable claws, special paw pads for extra traction, and a long tail for balance.

What are some adaptations of cheetahs?

Adaptations needed for rapid acceleration include a small, aerodynamic body frame, lightweight skeleton, and long leg and foot bones. The spine is highly flexible — another adaptation for an animal that makes sudden, long, and rapid strides.

What special adaptations make cheetahs so fast?

If that was not enough, cheetahs' semi-retractable claws, contrary to big cats, never fully retract, which means they are always ready to provide powerful traction to the ground. Other adaptations include wide nostrils, a powerful heart, and large lungs to allow more oxygen to the muscles, facilitating the sprinting.
