Here's the fastest 100-meter dash run by any living mammal (I'm not sure, though, whether some aquatic creatures might not beat that, and falcons, of course, can dive at 200 mph+).
National Geographic gives the story:
Sarah the cheetah has shattered the world record for the standing 100-meter dash, clocking a time of 5.95 seconds—making Olympian Usain Bolt's world record of 9.58 seconds look positively stodgy by comparison.
