By speed · Order from slowest to fastest.

1. 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.

2. A leaping blue marlin 108 km/h

   Marlins can change colour when excited, their stripes lighting up electric blue during a hunt.

3. A golf ball off the driver 340 km/h

   A driven golf ball can briefly spin thousands of times a minute, which is what makes it climb and hold the air.

4. The core of a jet stream 442 km/h

   Pilots ride these high-altitude winds to save fuel, which is why eastbound flights are often much quicker.

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. An F-22 Raptor at top speed 2.4K km/h

   The Raptor can supercruise, flying faster than sound without afterburners, sipping less fuel as it streaks along.
