The cheetah (Acinonyx jubatus) is an endangered member of the cat family (Felidae), a poor climber that hunts by speed and stealth. It is the fastest of all land animals and can reach speeds of more than 105 kilometres per hour (65 mph) in short bursts up to 460 metres (500 yd), as well as being able to accelerate from 0 to 110 kilometres per hour (68 mph) in three seconds. The word "cheetah" is derived from the Sanskrit word citrakāyaḥ चित्रकायः meaning "variegated body", via the Hindi cītā चीता.
