By speed · Order from slowest to fastest.

1. The creep of a mountain glacier 175320 mm/year

   Glaciers flow downhill under their own weight like very slow rivers of ice, grinding valleys as they go.

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 koala on the run 30 km/h

   Koalas sleep up to 22 hours a day because their eucalyptus diet is so low in energy and mildly toxic.

4. A charging lion 83 km/h

   Lions are the only big cats that live in groups, and a male's roar can be heard up to eight kilometres away.

5. 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.

6. A tank's sabot round 5.8K km/h

   A sabot round sheds a casing in flight, leaving a slim dart of dense metal that punches through armour.
