By speed · Order from slowest to fastest.

1. A migrating monarch butterfly 8 km/h

   Monarchs migrate thousands of kilometres to the same forests their great-grandparents left, guided by instinct alone.

2. A gray squirrel 19.5 km/h

   Squirrels plant thousands of trees by accident, forgetting where they buried many of the nuts they hid.

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 galloping racehorse 88 km/h

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

5. 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.

6. 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.
