Luckily, speed cameras do not exist in the world of animals. Many of the following animals would be caught in a radar trap. We have a detailed list of the fastest animals and exciting background information!
During a nose dive, the peregrine falcon is nearly as fast as a formula 1 racing car. The cheetah, the fastest terrestrial animal, would also probably be too fast for a common speedometer. It would be hardly possible to take a decent photo of it, because it can not only run incredibly fast, but changes direction while running, too. Faster than a speeding bullet!

Faster than Expected
Yet, the “slow” animals among the fastest are stunning as well: A cockroach can easily keep up with a briskly walking human. The tiger beetle is even faster. And if you are not fast enough on your bicycle, you could be overtaken by a leguan.
Average and Maximum Speed
While hunting or on the run, animals are able to move very fast for a short while. If you are late for the bus or for your first lesson at school you also tend to run much faster than usual. Yet, you cannot keep up this speed all day. This would be much too exhausting. The same with animals. The speeds listed here therefore apply for short distances only.
How to Measure Speed
The same cameras can be used that are applied to detect cars driving too fast. Sometimes stopwatches or collars with speedometers are used as well. Some scientists follow the animals in their cars and use the speedometer to determine their speed. All methods have in common that speed cannot be measured with absolute precision. Therefore, there is always different information and everyone claims to be right. Frequently, this causes scientific arguments. animalfunfacts.net therefore always specifies a range of speeds such as 55.9 - 74.5 mph (90 - 120 km/h).
It would not make sense to follow the cheetah with a car, as it frequently and abruptly changes its direction and cannot be trained to run straight for a long distance. In order to measure the speed of a cheetah you have to attach a collar to its neck and wait until it goes hunting for prey. But this still does not, mean that the cheetah is running at maximum speed. It only runs as fast as necessary to save energy – and only distances of 1312 - 1640 ft (400 - 500 m).
