About Hammerhead Shark:

  • The hammerhead sharks are a group of sharks in the family Sphyrnidae, so named for the unusual and distinctive structure of their heads, which are flattened and laterally extended into a “hammer” shape called a cephalofoil.
  • Most hammerhead species are placed in the genus Sphyrna, while the winghead shark is placed in its own genus, Eusphyra.
  • Many, but not necessarily mutually exclusive, functions have been proposed for the cephalofoil, including sensory reception, manoeuvering, and prey manipulation.
  • Hammerheads are found worldwide in warmer waters along coastlines and continental shelves.
  • Unlike most sharks, hammerheads usually swim in schools during the day, becoming solitary hunters at night.
  • Some of these schools can be found near Malpelo Island in Colombia, the Galapagos Islands in Ecuador, Cocos Island off Costa Rica, and near Molokai in Hawaii.
