1. A garden snail 50 m/h

   A snail can sleep for up to three years during droughts, sealing itself inside its shell until rain returns.

2. 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.

3. 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.

4. An ice hockey slapshot 178 km/h

   A slapshot flexes the stick like a spring, snapping stored energy into the puck for a brutal release.

5. A record tennis serve 270 km/h

   The fastest serves leave the racket so quickly the returner must react before the ball has even crossed the net.

6. The winds of a violent tornado 480 km/h
