By speed · Order from slowest to fastest.

1. A crawling baby 1.4 km/h

   Babies often invent their own crawling styles, from the classic hands-and-knees to a one-legged commando shuffle.

2. A swarming desert locust 14.5 km/h

   A single locust swarm can contain billions of insects and devour as much food in a day as tens of thousands of people.

3. A sea lion swimming 38 km/h

   Sea lions can be trained to detect underwater mines and even retrieve objects for navies.

4. A running pronghorn antelope 97 km/h

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

5. A Boeing 747 cruising 920 km/h

   The 747's hump exists because the cockpit was put on an upper deck so the nose could hinge open for cargo.

6. A bullet from a .357 Magnum 1.5K km/h

   A supersonic bullet creates a tiny sonic boom, which is part of the sharp crack you hear from a gunshot.
