Great Hammerhead

Perhaps the most distinctive marine animal of all—the Great Hammerhead has a unique hammer-shaped head that gives it large visual range. Like other sharks, the hammerhead has many teeth. More so than many think—about 17 rows of teeth on the upper and lower jaws. The shark feeds on fish and other marine prey such as octopi. However, hammerheads are extremely shy, and do not attack humans unless provoked or if they mistake one for an injured seal. There has been only one confirmed instance of a hammerhead killing a human.
