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 migrating monarch butterfly 8 km/h

   Monarchs migrate thousands of kilometres to the same forests their great-grandparents left, guided by instinct alone.

4. A running roadrunner 32 km/h

   Real roadrunners prefer sprinting to flying and can kill rattlesnakes, far from the cartoon's gentle dodging.

5. A galloping racehorse 88 km/h

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

6. A bullet train at full speed 330 km/h

   Japan's bullet trains have a near-perfect safety record, with average delays measured in seconds, not minutes.
