**#10: Pronghorn (88.5 km/h / 55 mph):** The Pronghorn isn't just fast; it's built for endurance, capable of sustaining high speeds over long distances on the North American plains thanks to its large lungs and heart. **#9: Sailfish (110 km/h / 68 mph):** Slicing through the ocean, the Sailfish is an aquatic missile. Its iconic dorsal fin, or "sail," helps herd fish and retracts for bursts of speed, making it a formidable hunter.
