By speed · Order from slowest to fastest.

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.

2. A manatee cruising 4.3 km/h

   Manatees are gentle plant-eaters so buoyant they use their heavy bones as ballast to keep from floating up.

3. 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.

4. A downhill speed skier 255 km/h

   Speed skiers tuck into an egg shape and wear airfoil helmets, accelerating faster than a free-falling skydiver.

5. A peregrine falcon in a dive 410 km/h

   The peregrine is the fastest animal on Earth, diving so fast it has baffles in its nostrils to breathe.

6. A top-fuel dragster 540 km/h

   A dragster covers a quarter mile in under four seconds, accelerating harder than a fighter jet off a carrier.
