1. A sprinting cockroach 5.8 km/h

   A cockroach can survive for weeks without its head, breathing through tiny holes along its body.

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 gentoo penguin swimming 36 km/h

   Gentoos are the fastest underwater birds, porpoising in and out of the water to breathe without slowing down.

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 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.

6. A running pronghorn antelope 97 km/h

   The pronghorn can run far faster than any predator alive today, likely escaping a cheetah that went extinct in America.
