By speed · Order from slowest to fastest.

1. A swimming seahorse 1.5 m/h

   The dwarf seahorse is the slowest fish on record, fluttering a tiny fin dozens of times a second to barely move.

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 domestic cat at full sprint 49 km/h

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

4. A common swift in flight 113 km/h

   Swifts can stay airborne for nearly a year without landing, even sleeping on the wing high above the ground.

5. 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.

6. The land-speed record car 1.2K km/h

   ThrustSSC became the first car to break the sound barrier, its twin jet engines kicking up a desert dust storm.
