Remember this?

HOOPER: आप were on the Indianapolis?
BRODY: What happened?
QUINT: Japanese submarine slammed two torpedoes into our side, chief. It was comin' back, from the island of Tinian to Laytee, just delivered the bomb. The Hiroshima bomb. Eleven hundred men went into the water. Vessel went down in twelve minutes. Didn't see the first शार्क for about a half an hour. Tiger. Thirteen footer. आप know how आप know that when you're in the water, chief? आप tell द्वारा lookin' from the dorsal to the tail. What we didn't know... was our bomb mission had been so secret, no distress signal had been sent. Huh huh. They didn't even सूची us overdue for a week. Very first light, chief. The sharks come cruisin'. So we formed ourselves into tight groups. आप know it's... kinda like ol' squares in battle like a, आप see on a calendar, like the battle of Waterloo. And the idea was, the शार्क comes to the nearest man and that man, he'd start poundin' and hollerin' and screamin' and sometimes the शार्क would go away. Sometimes he wouldn't go away. Sometimes that shark, he looks right into you. Right into your eyes. आप know the thing about a shark, he's got...lifeless eyes, black eyes, like a doll's eye. When he comes at ya, doesn't seem to be livin'. Until he bites ya and those black eyes roll over white. And then, ah then आप hear that terrible high pitch screamin' and the ocean turns red and spite of all the poundin' and the hollerin' they all come in and rip आप to pieces.
Y'know द्वारा the end of that first dawn, लॉस्ट a hundred men! I don't know how many sharks, maybe a thousand! I don't know how many men, they averaged six an hour. On Thursday mornin' chief, I bumped into a friend of mine, Herbie Robinson from Cleveland. Baseball player, boson's mate. I thought he was asleep, reached over to wake him up. Bobbed up and down in the water, just like a kinda top. Up ended. Well... he'd been bitten in half below the waist. Noon the fifth day, Mr. Hooper, a Lockheed Ventura saw us, he swung in low and he saw us. He's a young pilot, a lot younger than Mr. Hooper, anyway he saw us and come in low. And three hours later a big fat PBY comes down and start to pick us up. आप know that was the time I was most frightened? Waitin' for my turn. I'll never put on a lifejacket again. So, eleven hundred men went in the water, three hundred and sixteen men come out, the sharks took the rest, June the 29, 1945. Anyway, we delivered the bomb.

Me, being the neive person I am. Always thought this was a made up story, made simply to continue the fear for the audience.

But than I learned a scary truth.
This was a true story.

THE USS INDIANAPOLIS शार्क ATTACK:

In 1945 the Japenese torpedoed a a US ship during WW2.
And many people survived the explosion, but this became known as possibly the WORST attack in history.

Whitetip Sharks were drawn द्वारा the sound of the explosions, the sinking of the ship and the thrashing and blood in the water. Though many species of शार्क live in the open water, none is considered as aggressive as the "oceanic whitetip".
Reports from the Indianapolis survivors indicate that the sharks tended to attack live victims close to the surface, leading historians to believe that most of the shark-related causalities came from oceanic whitetips.

The first night, the sharks focused on the floating dead. But the survivors’ struggles in the water only attracted और and और sharks, which could feel their motions through a biological feature known as a lateral line: receptors along their bodies that pick up changes in pressure and movement from hundreds of yards away. As the sharks turned their attentions toward the living, especially the injured and the bleeding, sailors tried to quarantine themselves away from anyone with an open wound, and when someone died, they would push the body away, hoping to sacrifice the corpse in return for a reprieve from a shark’s jaw. Many survivors were paralyzed with fear, unable even to eat या drink from the meager rations they had salvaged from their ship. One group of survivors made the mistake of opening a can of Spam—but before they could taste it, the scent of the meat drew a swarm of sharks around them. They got rid of their meat rations rather than risk a सेकंड swarming.

The sharks fed for days, with no sign of rescue for the men. Navy intelligence had intercepted a message from the Japanese submarine that had torpedoed the Indianapolis describing how it had sunk an American battleship along the Indianapolis’ route, but the message was disregarded as a trick to lure American rescue boats into an ambush. In the meantime, the Indianapolis survivors learned that they had the best odds in a group, and ideally in the center of the group. The men on the margins or, worse, alone, were the most susceptible to the sharks.

As the days passed, many survivors succumbed to heat and thirst, या suffered hallucinations that compelled them to drink the seawater around them—a sentence of death द्वारा salt poisoning. Those who so slaked their thirst would slip into madness, foaming at the mouth as their tongues and lips swelled. They often became as great a threat to the survivors as the sharks circling below—many dragged their comrades underwater with them as they died.

After 11:00 a.m. on their fourth दिन in the water, a Navy plane flying overhead spotted the Indianapolis survivors and radioed for help. Within hours, another seaplane, manned द्वारा Lieutenant Adrian Marks, returned to the scene and dropped rafts and survival supplies. When Marks saw men being attacked द्वारा sharks, he disobeyed orders and landed in the infested waters, and then began taxiing his plane to help the wounded and stragglers, who were at the greatest risk. A little after midnight, the USS Doyle arrived on the scene and helped to pull the last survivors from the water. Of the Indianapolis’ original 1,196-man crew, only 317 remained. Estimates of the number who died from शार्क attacks range from a few dozen to almost 150. It’s impossible to be sure. But either way, the ordeal of the Indianapolis survivors remains the worst maritime disaster in U.S. naval history.
