The cheetah (Acinonyx jubatus) is the fastest land animal on Earth, capable of reaching speeds of 70 mph in short bursts covering distances up to 1,600 feet. They can accelerate from 0 to 60 mph in just 3 seconds, which is faster than most sports cars. This incredible speed makes them apex predators in the African savanna.
Cheetahs are diurnal hunters, meaning they hunt during the day, particularly in the early morning and late afternoon. They rely on their exceptional eyesight to spot prey from up to 3 miles away. Unlike other big cats that use stealth and power, cheetahs depend on speed and agility. They stalk their prey to within 200 to 230 feet before launching their attack.
Cheetahs primarily feed on small to medium sized ungulates including gazelles, impalas, and springboks. They also hunt hares, birds, and young wildebeest. After a successful hunt, cheetahs must eat quickly because they're not strong enough to defend their kill from larger predators like lions, leopards, and hyenas.
Cheetahs have distinctive black tear marks running from their eyes to their mouths, which help reduce sun glare and improve focus while hunting. Their bodies are built for speed: a lightweight frame, long legs, a flexible spine, enlarged heart and lungs, and semi retractable claws that provide extra grip like cleats on running shoes.
Female cheetahs give birth to litters of 3 to 5 cubs after a gestation period of about 90 to 95 days. Cubs are born with a silvery gray mantle of fur on their backs, which helps camouflage them from predators. The mother raises the cubs alone, teaching them to hunt. Only about 5% of cheetah cubs survive to adulthood due to predation from lions, leopards, and hyenas.
Unlike other big cats, cheetahs cannot roar. Instead, they produce a variety of vocalizations including purring (like domestic cats), chirping (bird like sounds to communicate with cubs), and stuttering (when excited or greeting each other). They also use scent marking and visual signals.
Cheetahs face numerous threats including habitat loss, human wildlife conflict, and illegal wildlife trade. Their population has declined by over 90% in the past 100 years, with only about 7,000 individuals remaining in the wild. They're listed as Vulnerable on the IUCN Red List. Conservation efforts focus on protecting habitats, reducing human wildlife conflict, and establishing protected corridors.
A cheetah's spine is so flexible it acts like a spring, allowing them to cover 25 feet in a single stride
Cheetahs are the only big cats that can turn mid-air while chasing prey, using their tail as a rudder
During a high-speed chase, a cheetah's respiratory rate increases from 60 to 150 breaths per minute
Cheetah cubs have a silvery-gray mantle of fur that makes them look like honey badgers, deterring predators
Unlike other big cats, cheetahs hunt during the day to avoid competition with nocturnal predators like lions
Cheetahs can reach top speeds of 70 mph (112 km/h) in short bursts covering distances up to 1,600 feet. They can accelerate from 0 to 60 mph in just 3 seconds, making them faster than most sports cars.
