1. A sprinting cockroach 5.8 km/h

   A cockroach can survive for weeks without its head, breathing through tiny holes along its body.

2. A casual cyclist 12.5 km/h

   The bicycle is one of the most efficient machines ever made, turning muscle into distance better than walking.

3. A honeybee in flight 22 km/h

   Bees communicate the direction of flowers by dancing, encoding distance and angle in their waggling moves.

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 leaping blue marlin 108 km/h

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

6. A maglev train at record speed 460 km/h

   Maglev trains float on magnets with no wheels, so the only friction left to overcome is the air itself.
