The sailfish is widely considered the fastest animal to swim.
This majestic fish can reach speeds of up to 68 miles per hour (109 kilometers per hour) in short bursts.
Its incredible speed is attributed to its streamlined body shape, powerful tail, and unique sail-like dorsal fin.
The sailfish uses its dorsal fin to generate lift and propel itself forward, similar to a sailboat using its sail.
While the sailfish is undoubtedly the fastest, other contenders for the title include the black marlin and the shortfin mako shark.
These marine creatures also possess impressive speed capabilities, reaching speeds of up to 50 miles per hour (80 kilometers per hour) and 40 miles per hour (64 kilometers per hour), respectively.
