How does a sharks speed compare with tuna fishes?

Sharks and tuna are both fast swimmers, but tuna generally have the edge in speed. For example, some species of tuna, like the yellowfin tuna, can reach speeds of up to 75 miles per hour (120 km/h), while most sharks, such as the great white shark, typically swim at speeds of around 25 miles per hour (40 km/h) but can sprint up to 35 miles per hour (56 km/h) in short bursts. Tuna also have streamlined bodies and specialized muscles that allow for sustained high-speed swimming, making them some of the fastest fish in the ocean. Overall, while sharks are powerful swimmers, tuna are generally faster.
