Behavior and Habitat

• Typical behavior patterns: Great Hammerhead Sharks are known for their unique swimming style. They move their heads side to side, which helps them find prey. These sharks are mostly solitary hunters. They are active during the day and night. They use their wide heads to pin stingrays to the ocean floor. This makes it easier for them to catch their prey.
• Preferred habitats: Great Hammerhead Sharks prefer warm waters. They are often found near coastlines and continental shelves. They like areas with coral reefs and seagrass beds. These places are rich in food. Sometimes, they can be seen in open oceans, but they usually stay near the surface or at moderate depths.

Depth	Surface to moderate depths

Conservation Status of Hammerhead Sharks

• Current Conservation Status of Different Species

  Hammerhead sharks are facing various levels of threat. Some species are more endangered than others. For example, the Great Hammerhead is listed as “Critically Endangered” by the International Union for Conservation of Nature (IUCN). Other species like the Scalloped Hammerhead are also in trouble and are listed as “Endangered.”
• Threats to Hammerhead Sharks

  Hammerhead sharks face many threats. One of the biggest threats is overfishing. They are often caught for their fins, which are used in shark fin soup. Another threat is habitat loss. Pollution and climate change are making it hard for them to find food and safe places to live.

• Conservation Efforts

  Many people and organizations are working to save hammerhead sharks. Some countries have made laws to protect them. There are also marine protected areas where fishing is not allowed. Scientists are studying hammerhead sharks to learn more about them and how to help them survive.

Species	Conservation Status
Great Hammerhead	Critically Endangered
Scalloped Hammerhead	Endangered
Smooth Hammerhead	Vulnerable
