By speed · Order from slowest to fastest.

1. The growth of a cave stalactite 0.1 mm/year

   Most stalactites lengthen by less than a tenth of a millimetre a year, dripping mineral by mineral over millennia.

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 swarming desert locust 14.5 km/h

   A single locust swarm can contain billions of insects and devour as much food in a day as tens of thousands of people.

4. A yellowfin tuna 73 km/h

   Tuna are warm-blooded among mostly cold-blooded fish, letting their muscles fire faster for high-speed chases.

5. A car cruising the German autobahn 200 km/h

   Parts of Germany's autobahn have no speed limit, where ordinary sedans legally travel faster than racetracks allow elsewhere.

6. A hypersonic missile 9.8K km/h

   Hypersonic weapons fly so fast and low they are extremely hard to track and intercept in time.
