Hammerhead sharks are a unique group of sharks known for their distinctive head shape, which resembles a hammer. This unusual structure, called a cephalofoil, helps them to have better vision and improved sensory capabilities, allowing them to detect prey more effectively. There are several species of hammerhead sharks, with the great hammerhead being the largest. These sharks are typically found in warm waters around the world, often near coastlines and in deeper oceanic regions. Hammerhead sharks are social creatures and are known to form schools, especially during the day. They primarily feed on fish, squid, and other marine animals, making them important predators in their ecosystems.
