By speed · Order from slowest to fastest.

1. 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.

2. A scurrying hedgehog 6.4 km/h

   A startled hedgehog rolls into a tight ball, raising up to 6,000 spines that few predators dare to bite.

3. An Olympic swimmer at full speed 9.3 km/h

   Top swimmers shave their bodies to cut drag, trimming fractions of a second that can decide a gold medal.

4. A running gray wolf 57 km/h

   Wolves can travel over 30 kilometres in a single day while hunting across their vast territories.

5. A racing snowmobile 190 km/h

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

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.
