We spent several hours with these incredible sharks, here's a natural sound look at what it's like to spend time with these incredible creatures. This was recorded off the coast of Bimini, Bahamas on the live about M/V Shear Water.
Here are the top 10 facts about great hammerhead sharks:
1. Distinct Hammer-Shaped Head: The great hammerhead shark is easily recognized by its unique hammer-shaped head, which accounts for nearly a quarter of its total body length. This unusual head shape is believed to enhance their ability to locate prey through improved sensory perception and vision.
2. Size Matters: Great hammerheads are among the largest sharks in the world, with some individuals reaching lengths of up to 20 feet (6 meters) and weighing up to 1,000 pounds (450 kg).
3. Wide Distribution: These sharks are found in tropical and warm temperate waters worldwide, including the Atlantic, Pacific, and Indian Oceans, as well as the Mediterranean Sea.
4. Solitary Hunters: Great hammerheads are typically solitary hunters, but they can also form small groups during migration or when attracted to abundant food sources.
5. Sophisticated Sensory System: In addition to their unique head shape, great hammerheads have highly developed sensory organs, including electroreceptors that allow them to detect the electrical fields generated by prey animals.
6. Apex Predators: These sharks are apex predators, feeding on a variety of prey, including fish, stingrays, and other sharks. They are known for their powerful jaws and serrated teeth.
7. Migratory Behavior: Great hammerheads undertake long migrations, traveling thousands of miles across the open ocean, likely following their prey and suitable water temperatures.
8. Viviparous Reproduction: Like most sharks, great hammerheads are viviparous, meaning they give birth to live young after an extended gestation period of around 11 months.
9. Conservation Status: The great hammerhead shark is listed as "Critically Endangered" on the International Union for Conservation of Nature (IUCN) Red List due to overfishing and habitat loss.
10. Unique Mating Behavior: During mating season, male great hammerheads engage in a behavior called "doughnuting," where they continuously swim in a tight circle around the female, likely to prevent other males from interfering.
