1. A crawling slug 30 m/h

   A slug glides on a ribbon of self-made slime, which lets it cross even a razor's edge unharmed.

2. 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.

3. A bottlenose dolphin 60 km/h

   Dolphins sleep with half their brain at a time, keeping one eye open to breathe and watch for danger.

4. A galloping racehorse 88 km/h

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

5. An IndyCar on an oval 390 km/h

   IndyCars on superspeedways run flat-out for hours, with drivers enduring forces that strain the neck lap after lap.

6. An F-22 Raptor at top speed 2.4K km/h
