what is the fastest animal?

## Fastest Animals by Category **In the air:** The **peregrine falcon** is the fastest animal on Earth, reaching speeds of **240–320 km/h (150–200 mph)** during a hunting dive (stoop). In level flight, it travels around 100 km/h. **On land:** The **cheetah** holds the record, reaching speeds of **112–120 km/h (70–75 mph)** in short bursts of up to 500 meters. It can accelerate from 0 to 96 km/h in about 3 seconds. **In water:** The **sailfish** is considered the fastest fish, clocking speeds of around **110 km/h (68 mph)**. The **black marlin** is also a strong contender at similar speeds. **Overall context:** If diving speed counts, the peregrine falcon is the undisputed fastest animal. If only sustained, self-powered horizontal movement is considered, rankings shift depending on the medium (air, land, or water).
