Largest hammerhead shark species

Of the nine currently-recognised species of hammerhead shark, by far the largest is the great hammerhead Sphyrna mokarran, which attains a maximum length of 6.1 m (20 ft). It inhabits tropical waters around all of the world's continents except Europe, and can sometimes be encountered in reefs as shallow as 1 m (3 ft), despite its very impressive size – at least a third longer than any other hammerhead species.
