By speed · Order from slowest to fastest.

1. A chameleon on the move 350 m/h

   A chameleon's eyes swivel independently, so it can watch two directions at once before its slow, swaying steps.

2. A giant tortoise 500 m/h

   Giant tortoises can live over 150 years, ambling through more than a century of slow, steady days.

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 peregrine falcon in a dive 410 km/h

   The peregrine is the fastest animal on Earth, diving so fast it has baffles in its nostrils to breathe.

5. A 5.56mm rifle bullet 3.1K km/h

   Small, fast rifle rounds tumble on impact, transferring energy in ways a slower, heavier bullet would not.

6. The Earth orbiting the Sun 107K km/h

   We are all hurtling around the Sun fast enough to cross between two cities in a single second, yet we feel nothing.
