SortStack #680 — 2028-04-19

By speed · Order from slowest to fastest.

1. A three-toed sloth 240 m/h

   Sloths move so slowly that algae grows in their fur, giving them a greenish camouflage in the canopy.

2. 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.

3. A yellowfin tuna 73 km/h

   Tuna are warm-blooded among mostly cold-blooded fish, letting their muscles fire faster for high-speed chases.

4. A record fastball pitch 169 km/h

   A 100-mile-an-hour pitch reaches home plate in under four-tenths of a second, faster than a blink of choice.

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. A Bugatti Chiron at top speed 510 km/h

   The Chiron is electronically limited; unleashed, its tyres would tear themselves apart from the sheer forces.
