Conservation Status
The International Union for Conservation of Nature (IUCN) classifies several species of Hammerhead Sharks as endangered. Climate change, overfishing, and loss of habitat contribute to their declining population. Conservation efforts include strict fishing regulations, habitat preservation, and public awareness campaigns for their protection.
