Abstract

Built for speed, the cheetah (Acinonyx jubatus) is adapted for a running lifestyle. This chapter covers musculoskeletal and thermoregulatory adaptations that contribute in making it the world's fastest land mammal. It also covers physiological and morphological traits relating to characteristics of the cheetah's physical appearance, vocalizations, visual systems, and organ systems. The cheetah's spotted coat confers camouflage protection. The cheetah has a small head with reduced tooth-size, long limbs with semiretractile claws, and a flexible spine that increases the cheetah's stride. Unable to roar, cheetahs purr, sharing osteological anatomy with domestic cats. Cheetahs also have a visual system that is distinct from other cats, with more short wavelength cones and visual acuity based on the horizon. Physiological adaptations are seen in skeletal musculature, and the fact that cheetahs dissipate heat quickly during and after a hunt through specialized and enlarged nasal passages. These combined characteristics make the cheetah a unique felid species.
