1. A three-toed sloth 240 m/h

   Sloths move so slowly that algae grows in their fur, giving them a greenish camouflage in the canopy.

   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. An electric scooter 25 km/h

   Shared e-scooters exploded across cities in just a few years, becoming a common sight on sidewalks worldwide.

5. A powerful soccer free kick 132 km/h

   A well-struck free kick can swerve in mid-air as spin and airflow bend its path around a defensive wall.

6. A tsunami across the open ocean 800 km/h

   In deep water a tsunami is barely a ripple, racing as fast as a jet before rearing up near the shore.
