1-5 Facts About Hammerhead Sharks
1. Hammerhead sharks have never been known to kill a human. Since records began in 1580, there have been only 17 reported unprovoked shark attacks by hammerheads, and all of them were non-fatal. Despite their fearsome appearance, hammerhead sharks are generally not considered a threat to humans.
2. During the filming of Jaws 2, cast members were circled by actual hammerhead sharks. The scene required the actors to yell for help, and the crew did not immediately realize they were in danger due to the presence of real hammerhead sharks.
3. Hammerhead sharks are one of the few animals known to reproduce asexually, a process called parthenogenesis. This means that female hammerhead sharks can produce offspring without mating with a male, although this form of reproduction is relatively rare in sharks.
4. There is a legendary hammerhead shark known as “Old Hitler” that is reported to be 20 feet long and has a swastika-shaped scar. This shark is said to have been patrolling the Gulf Coast of Florida for decades, although there is limited scientific evidence to support this claim.
5. Hammerhead sharks typically reproduce once a year, with the male shark biting the female shark violently until she agrees to mate with him. This mating behavior, known as “mating scars,” is believed to be a form of courtship ritual among hammerhead sharks.

6. Hammerhead sharks are known to travel in schools, often consisting of up to 500 sharks, during the day. However, at night, they may split up into smaller groups or even go solo. The reasons for this behavior are not yet fully understood and are still being studied.
7. Hammerhead sharks are known to congregate in certain areas around the world, such as Cocos Island (Costa Rica), Wolf and Darwin in the Galapagos (Ecuador), Rangiroa in French Polynesia, and The Bahamas. Divers often have amazing encounters with groups of hammerheads in these destinations, making them popular diving spots for shark enthusiasts.
8. The great hammerhead is the largest species of hammerhead shark, typically measuring about 13 feet in length and weighing about 500 pounds on average. However, sizes can vary among individuals and populations.
9. A single female can give birth to anywhere from six to 50 pups, depending on the species.
10. Baby hammerhead sharks have a round head to ease the live birthing process of the mother sharks.
1-5 Facts About Hammerhead Sharks
11. Hammerhead sharks have a unique feature that sets them apart from other shark species – their distinctively shaped head is called a “cephalofoil,” which resembles a hammer or a T-shaped structure.
12. This cephalofoil is believed to provide the shark with enhanced sensory perception, including the ability to “see” magnetic fields, which helps them navigate and locate prey in its environment.
13. There are at least nine known species of hammerhead sharks, including the scalloped hammerhead, great hammerhead, smooth hammerhead, smalleye hammerhead, Carolina hammerhead, whitefin hammerhead, scalloped bonnethead, scoophead, and bonnethead. However, some studies may suggest the existence of more species.
14. Two species of hammerhead sharks, the scalloped hammerhead and the great hammerhead are considered critically endangered, while the smooth hammerhead is considered vulnerable. The main threats to hammerhead sharks are bycatch in fishing gear and the global shark fin trade.
15. The winghead shark, a species of hammerhead shark, has the widest head relative to its body size among all hammerhead sharks. The width of its head is almost half as wide as its body length. Winghead sharks are found in the Indo-Pacific region and are known to get tangled up in fishing nets due to their unique head shape.
1-5 Facts About Hammerhead Sharks
16. Hammerhead sharks are known for using their head to ram and pin down prey, tiring them out and making them easier to eat. This unique feeding behavior is often referred to as “hammer-action” and is an adaptation that sets them apart from other shark species.
17. Hammerhead sharks have unique eyes that allow them to have a 360-degree field of vision. However, this adaptation also comes with a blind spot right in front of their nose.
18. Sharks have been around for a very long time and can be traced back to at least 420 million years ago. However, hammerhead sharks are considered relatively “newer” evolved shark species, as they have been around for approximately 20-25 million years, which is relatively recent compared to the overall timeline of sharks and their evolution.

19. Hammerhead sharks can tan. They have special cells in their skin called chromatophores that can expand or contract to change their skin coloration, allowing them to adapt to different environments and potentially protect themselves from UV radiation.
20. Great hammerhead sharks are known to swim sideways at times, which is a unique behavior among sharks.
