(from thoughtco): "The great hammerhead shark (Sphyrna mokarran) is the largest of the 9 species of hammerhead sharks. These sharks are easily recognized by their unique hammer or shovel-shaped heads. The great hammerhead can reach a maximum length of about 20 feet, but their average length is about 12 feet. Their maximum length is about 990 pounds. They have a grayish-brown to light gray back and white underside. Great hammerhead sharks have a notch in the center of their head, which is known as a cephalofoil. The cephalofoil has a gentle curve in juvenile sharks but becomes straight as the shark ages. Great hammerhead sharks have a very tall, curved first dorsal fin and a smaller second dorsal fin. They have 5-gill slits. Hammerhead sharks are usually not dangerous to humans, but great hammerheads should be avoided due to their size. Hammerhead sharks, in general, are listed by the International Shark Attack File #8 on its list of species responsible for shark attacks from the years 1580 to 2011. During this time, hammerheads were responsible for 17 non-fatal, unprovoked attacks and 20 fatal, provoked attacks."
