â¢ Hammerhead Sharks. There are several species of hammerhead sharks, which are in the family Sphyrnidae. These species include the winghead, mallethead, scalloped hammerhead, scoophead, great hammerhead and bonnethead sharks. These sharks differ from other sharks, as they have very unique hammer-shaped heads.
Sharks belong to the class of boneless fish known as Chondrichthyes. The Chondrichthyes class is divided in two sub-classes Holocephali {Chimeras) and Elasmobranchii {Sharks and Rays}. Similar species of sharks are put into Families, and families with similar characteristics are placed in larger groups called Orders.
