By speed · Order from slowest to fastest.

1. A duck paddling on water 1.6 km/h

   Ducks have no nerves or blood vessels in their feet, so they can paddle in icy water without feeling the cold.

2. A Komodo dragon walking 4.8 km/h

   The largest lizard alive, it has venom glands and a bite that can topple prey far larger than itself.

3. A swordfish 102 km/h

   A swordfish has special organs that heat its eyes and brain, sharpening its vision in cold, deep water.

4. A racing snowmobile 190 km/h

   Snowmobiles can cross frozen lakes so fast they sometimes skip right across patches of open water.

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. The Earth orbiting the Sun 107K km/h

   We are all hurtling around the Sun fast enough to cross between two cities in a single second, yet we feel nothing.
