1. 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.

   Shared e-scooters exploded across cities in just a few years, becoming a common sight on sidewalks worldwide.

3. A running roadrunner 32 km/h

   Real roadrunners prefer sprinting to flying and can kill rattlesnakes, far from the cartoon's gentle dodging.

4. A charging black rhinoceros 54 km/h

   A rhino's horn is made of keratin, the same material as your hair and nails, not bone.

5. A swordfish 102 km/h

   A swordfish has special organs that heat its eyes and brain, sharpening its vision in cold, deep water.

6. A top-fuel dragster 540 km/h

   A dragster covers a quarter mile in under four seconds, accelerating harder than a fighter jet off a carrier.
