Fastest animals in the world
Fastest animal in a dive: peregrine falcon. Fastest on land: cheetah. Fastest fish often listed: sailfish. Why “fastest” needs a habitat.
“Fastest animal” depends on the medium. In a hunting stoop, the peregrine falcon is usually first — over 300 km/h in a dive. In level flight, some swifts and the common swift records compete.
On land the cheetah is the sprint champion, roughly 100–120 km/h for a short burst. It cannot hold that speed. Pronghorn and some antelopes win longer chases. Humans are poor sprinters and good long-distance runners in the heat.
In water, sailfish and black marlin appear at the top of popular lists (around 100 km/h in bursts). Treat internet “fastest ever” videos as entertainment until a paper measures them.

What is the fastest animal in the world?
Say the habitat. Dive: peregrine. Land: cheetah. Water: sailfish on many lists.
How fast is a cheetah?
About 100–120 km/h for a few hundred metres, then it overheats.
Is a horse faster than a human?
Yes in a sprint. A fit human can still beat a horse over very long, hot distances — that is a physiology story, not a race rule.
