Although there are nine different species of hammerhead shark in the world, the great hammerhead is the biggest. While our great hammerhead is about 7 feet long, the largest on record was 20 feet long and over 950 lbs. The head is rounded on the juvenile hammerhead shark but as it matures, the head "flattens" creating a rectangular shape. The common name is derived from the hammer shape of the shark's head. The eyes and nostrils are located on the far sides of the head.
