Genus Sphyrna, also known as hammerhead sharks, is a group of sharks characterized by their unique "hammerhead" shaped heads. While the scientific name remains the same, there are several synonyms used to refer to these sharks in popular culture. These include hammerheads, hammerhead sharks, and Sphyrnids. Hammerhead sharks are known for their unusual head shape, which allows for enhanced vision and directional precision while hunting. There are several species in the Genus Sphyrna, including the common hammerhead, scalloped hammerhead, and great hammerhead. Despite their intimidating appearance, these sharks are relatively harmless to humans and are a fascinating study in evolutionary adaptations.
