    Hammerhead Sharks

    How well do you know them?

    • There are 10 species of hammerhead sharks. The largest member is the 20’-long great hammerhead (Sphyrna mokarran) and the smallest is the petite 3’-long scalloped bonnethead (Sphyrna corona).
    • In 2013, the 10th species of hammerhead was discovered, the Carolina hammerhead (Sphyrna gilberti). What makes it so special? It has 10 less vertebrae than its nearly identical family member, the scalloped hammerhead.
    • Their hammer-shaped head is called a cephalofoil and it increases their ability to sense prey using electroreception. This is due to the unique number and distribution of electrical sensors called ampullae of Lorenzini.
    • Hammerhead sharks have a 360° view of the ocean around them. Dr. Mikki McComb-Kobza, Executive Director of http://www.oceanfirstinstitute.org/, discovered this during her research.
    • Hammerhead moms give birth to a litter of live young, called pups. Although there is no maternal care, the babies are born ready to thrive.
