By speed · Order from slowest to fastest.

1. A crawling slug 30 m/h

   A slug glides on a ribbon of self-made slime, which lets it cross even a razor's edge unharmed.

2. A foraging ant 800 m/h

   Ants leave scent trails so nestmates can retrace the exact path to food, like an invisible chemical map.

3. A person walking 5 km/h

   The average person takes around 7,000 steps a day, walking the equivalent of several times around Earth in a lifetime.

4. A casual cyclist 12.5 km/h

   The bicycle is one of the most efficient machines ever made, turning muscle into distance better than walking.

5. 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.

6. An F-22 Raptor at top speed 2.4K km/h

   The Raptor can supercruise, flying faster than sound without afterburners, sipping less fuel as it streaks along.
