Some sharks are fast and some sharks are slow, but the great majority cruise at very low speeds. While great whites, blues, and makos are capable of a great speed burst, most sharks swim at around 1.5 miles per hour when they're not actively chasing prey or attempting to escape from a dangerous situation. This speed falls about in line with the average human swim speed, which is between 1 and 2 miles per hour.
Behavior [edit]. The shortfin mako shark is the fastest species of shark. Its speed has been recorded at 40 km/h (25 mph) with bursts of up to 74 km/h (46 mph). This high-leaping fish-they can leap approximately 9 m (30 ft) high or higher in the air-is a highly sought-after game fish worldwide.
