By speed · Order from slowest to fastest.

1. The growth of human hair 175.3 mm/year

   Scalp hair grows roughly 1.25 centimetres a month, so a single strand reaching your shoulders is years old.

2. A duck paddling on water 1.6 km/h

   Ducks have no nerves or blood vessels in their feet, so they can paddle in icy water without feeling the cold.

3. A mosquito in flight 2.4 km/h

   Only female mosquitoes bite; they need a blood meal to develop their eggs, while males sip flower nectar.

4. A Komodo dragon walking 4.8 km/h

   The largest lizard alive, it has venom glands and a bite that can topple prey far larger than itself.

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 golf ball off the driver 340 km/h

   A driven golf ball can briefly spin thousands of times a minute, which is what makes it climb and hold the air.
