1. A foraging ant 800 m/h

   Ants leave scent trails so nestmates can retrace the exact path to food, like an invisible chemical map.

2. A manatee cruising 4.3 km/h

   Manatees are gentle plant-eaters so buoyant they use their heavy bones as ballast to keep from floating up.

3. A gray squirrel 19.5 km/h

   Squirrels plant thousands of trees by accident, forgetting where they buried many of the nuts they hid.

4. A domestic cat at full sprint 49 km/h

   A house cat can outsprint many dogs over short distances, but tires quickly after the burst.

5. A speeding hovercraft 145 km/h

   A hovercraft floats on a cushion of trapped air, gliding equally well over water, land, ice and mud.

6. A Cessna light aircraft 220 km/h
