By speed · Order from slowest to fastest.

1. A galloping zebra 66 km/h

   No two zebras have the same stripe pattern, which may help them recognise each other and confuse biting flies.

2. A charging lion 83 km/h

   Lions are the only big cats that live in groups, and a male's roar can be heard up to eight kilometres away.

3. A running pronghorn antelope 97 km/h

   The pronghorn can run far faster than any predator alive today, likely escaping a cheetah that went extinct in America.

4. A common swift in flight 113 km/h

   Swifts can stay airborne for nearly a year without landing, even sleeping on the wing high above the ground.

5. A record badminton smash 565 km/h

   The shuttlecock is the fastest object in any racket sport, though it decelerates almost as quickly as it launches.

6. A volcanic pyroclastic flow 700 km/h

   A pyroclastic flow is a searing avalanche of gas and ash that buried Pompeii's residents almost instantly.
