how do they kill jaws in jaws 3
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.
Shark attack Only a few types of sharks are dangerous to humans. Out of more than 480 shark species, only three are responsible for two-digit numbers of fatal unprovoked attacks on humans: the great white, tiger and bull;[2] however, the oceanic whitetip has probably killed many more castaways which have not been recorded in the statistics.[3] These sharks, being large, powerful predators, may sometimes attack and kill people; however, they have all been filmed in open water by unprotected divers.[26][27] The 2010 French film Oceans shows footage of humans swimming next to sharks in the ocean. It is possible that the sharks are able to sense the presence of unnatural elements on or about the divers, such as polyurethane diving suits and air tanks, which may lead them to accept temporary outsiders as more of a curiosity than prey. Uncostumed humans, however, such as those surfboarding, light snorkeling or swimming, present a much greater area of exposed skin surface to sharks. In addition, the presence of even small traces of blood, recent minor abrasions, cuts, scrapes or bruises, may lead sharks to attack a human in their environment. Sharks seek out prey through electroreception, sensing the electric fields that are generated by all animals due to the activity of their nerves and muscles.
