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 koala on the run 30 km/h

   Koalas sleep up to 22 hours a day because their eucalyptus diet is so low in energy and mildly toxic.

3. A galloping racehorse 88 km/h

   All thoroughbred racehorses descend from just three stallions imported to England centuries ago.

4. A cheetah at full sprint 120 km/h

   A cheetah can go from a standstill to highway speed faster than most sports cars, but only for a few seconds.

5. A bullet from an AK-47 2.7K km/h

   The AK-47 is the most widely produced firearm in history, prized for working even when caked in mud and sand.

6. The SR-71 Blackbird 3.5K km/h

   The Blackbird leaked fuel on the ground because its panels only sealed once heat expanded them in flight.
