1. A chicken foraging 3.6 km/h

   Chickens can recognise over a hundred individual faces, both other birds and the humans who feed them.

2. A housefly in flight 6.8 km/h

   A housefly tastes with its feet, so it can decide whether something is food the moment it lands on it.

3. A charging African elephant 28 km/h

   Despite their bulk, elephants are the only animals that cannot jump, keeping at least one foot down at all times.

4. A powerful soccer free kick 132 km/h

   A well-struck free kick can swerve in mid-air as spin and airflow bend its path around a defensive wall.

5. A golden eagle in a dive 245 km/h

   A golden eagle can spot a rabbit from over three kilometres away, then fold its wings into a lethal stoop.

6. 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.
