By speed · Order from slowest to fastest.

1. A foraging ant 800 m/h

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

2. 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.

3. A striking barracuda 42 km/h

   Barracudas can lunge in sudden bursts to ambush prey, sometimes mistaking a swimmer's shiny jewellery for fish.

4. A leaping blue marlin 108 km/h

   Marlins can change colour when excited, their stripes lighting up electric blue during a hunt.

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 volcanic pyroclastic flow 700 km/h

   A pyroclastic flow is a searing avalanche of gas and ash that buried Pompeii's residents almost instantly.
