How fast does a hammerhead shark swim?

A hammerhead shark can swim at speeds of up to 25 miles per hour (40 kilometers per hour) in short bursts, especially when chasing prey or evading predators. Their unique, flattened head (called a cephalofoil) provides enhanced maneuverability and allows them to make sharp turns, making them agile hunters in the water. However, during normal activity, they typically swim at slower speeds.
