SortStack #3207 — 2035-03-21

By speed · Order from slowest to fastest.

1. A garden snail 50 m/h

   A snail can sleep for up to three years during droughts, sealing itself inside its shell until rain returns.

2. A gentoo penguin swimming 36 km/h

   Gentoos are the fastest underwater birds, porpoising in and out of the water to breathe without slowing down.

3. A red fox 51 km/h

   Foxes may use Earth's magnetic field to aim their pounces, lining up on prey hidden under snow.

4. 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.

5. The core of a jet stream 442 km/h

   Pilots ride these high-altitude winds to save fuel, which is why eastbound flights are often much quicker.

6. A Bugatti Chiron at top speed 510 km/h

   The Chiron is electronically limited; unleashed, its tyres would tear themselves apart from the sheer forces.
