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 king penguin waddling on land 2.8 km/h

   A penguin's waddle is surprisingly efficient, storing and releasing energy with each side-to-side rock.

3. A gentoo penguin swimming 36 km/h

   Gentoos are the fastest underwater birds, porpoising in and out of the water to breathe without slowing down.

4. A record fastball pitch 169 km/h

   A 100-mile-an-hour pitch reaches home plate in under four-tenths of a second, faster than a blink of choice.

5. A car cruising the German autobahn 200 km/h

   Parts of Germany's autobahn have no speed limit, where ordinary sedans legally travel faster than racetracks allow elsewhere.

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.
