1. A honeybee in flight 22 km/h

   Bees communicate the direction of flowers by dancing, encoding distance and angle in their waggling moves.

2. 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.

   The pronghorn can run far faster than any predator alive today, likely escaping a cheetah that went extinct in America.

   A modern compound bow uses pulleys to store huge energy, launching an arrow with deadly accuracy.

5. The X-15 rocket plane 7.3K km/h
