By speed · Order from slowest to fastest.

1. A chameleon on the move 350 m/h

   A chameleon's eyes swivel independently, so it can watch two directions at once before its slow, swaying steps.

2. A sea turtle cruising 3 km/h

   Sea turtles can hold their breath for hours while resting, slowing their heart to a beat every few minutes.

3. A chicken foraging 3.6 km/h

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

4. 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.

5. A peregrine falcon in a dive 410 km/h

   The peregrine is the fastest animal on Earth, diving so fast it has baffles in its nostrils to breathe.

6. The Earth orbiting the Sun 107K km/h

   We are all hurtling around the Sun fast enough to cross between two cities in a single second, yet we feel nothing.
