where did the hammerhead shark get its name
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, Cocos Island off Costa Rica, and near Molokai in Hawaii. Large schools are also seen in the waters off southern and eastern Africa.
Jaws 3-D Hearing the shark has been lured into the pipe, Michael and Kay go down to repair the underwater tunnel, so the technicians can restore air pressure and drain the water. Calvin orders the pump to be shut down to suffocate the shark, but this act instead allows her to break free from the pipe and attack Michael and Kay, but they are saved by the dolphins. They make their way back to the control room, but the shark appears in front of the window and smashes through the glass, flooding the room and killing a technician. Michael notices FitzRoyce's corpse still in the shark's throat with a grenade, and uses a bent pole to pull its pin, triggering the grenade's explosion and killing the shark. In the aftermath, Mike and Kay celebrate with the dolphins, who survived their brush with the shark.
