By speed · Order from slowest to fastest.

1. A housefly in flight 6.8 km/h

   A housefly tastes with its feet, so it can decide whether something is food the moment it lands on it.

2. A charging African elephant 28 km/h

   Despite their bulk, elephants are the only animals that cannot jump, keeping at least one foot down at all times.

3. A falling raindrop 34 km/h

   Raindrops are not teardrop-shaped; they flatten into tiny hamburger buns as they fall through the air.

4. A domestic cat at full sprint 49 km/h

   A house cat can outsprint many dogs over short distances, but tires quickly after the burst.

5. A running reindeer 80 km/h

   Reindeer eyes change colour with the seasons, turning blue in winter to see better in the dim Arctic light.

6. The core of a jet stream 442 km/h

   Pilots ride these high-altitude winds to save fuel, which is why eastbound flights are often much quicker.
