   Foxes may use Earth's magnetic field to aim their pounces, lining up on prey hidden under snow.

   No two zebras have the same stripe pattern, which may help them recognise each other and confuse biting flies.

3. A cheetah at full sprint 120 km/h

   A cheetah can go from a standstill to highway speed faster than most sports cars, but only for a few seconds.

4. A racing snowmobile 190 km/h

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

   An intercontinental missile arcs into space before plunging back down, its warhead glowing from the friction.

6. NASA's Parker Solar Probe 692K km/h
