Human bone crushes at about 11159 kg per square inch. This means we’d have to dive to about 35.5 km depth before bone crushes. This is three times as deep as the deepest point in our ocean.

The pressure from the water would push in on the person’s body, causing any space that’s filled with air to collapse. (The air would be compressed.) So, the lungs would collapse. At the same time, the pressure from the water would push water into the mouth, filling the lungs back up again with water instead of air.

Decompression sickness: Often called “the bends,” decompression sickness happens when a scuba diver ascends too quickly. But if a diver rises too quickly, the nitrogen forms bubbles in the body. This can cause tissue and nerve damage. In extreme cases, it can cause paralysis or death if the bubbles are in the brain.

If you’re wondering if 47 meters down is a true story or not, it’s not true. The film 47 Meters Down is a horror survival film and was directed by Johannes Roberts. This fictional story, which has received mixed reviews, was written by Johannes Roberts and Ernest Riera.

In the reality of 47 Meters Down’s ending, Kate is shark bait. She’s dead. Lisa survives. But at least for a moment, Lisa got the happy ending we wished for her and her sister.

No human has ever died by shark attack in a shark cage diving accident, making many believe shark cage diving is safe. The diver was forced to exit the cage and swim to the surface, surviving with the help of the boat captain who fended off the shark by jabbing at its head and disorientating the animal.

Massive amounts of chumming in a confined area where people are in the water is obviously a bad idea. By definition, chumming attracts sharks that are motivated to feed, and bringing people and sharks into close proximity raises the risk that a bite or attack on a human will occur.

In reality, a cage’s strength is just a precaution. Sharks tend to bite things that look like they’d taste good. They almost never bite a shiny metal box.

Can You Swim With Great White Sharks Without a Cage? No, you can’t. Swimming with great whites is inherently dangerous. These are large and powerful predators who have eaten people in the past.

Stay calm and do not make sudden movements.

1. Move slowly toward the shore or a boat; choose whichever is closest. Do not thrash your arms or kick or splash while you swim.
2. Do not block the shark’s path. If you are standing between the shark and the open ocean, move away.
3. Do not turn your back on the shark as you move.

Given that sharks don’t generally consider humans food, and that they have good reason to fear us, why do sharks attack people? The most common reason is likely to be that they get confused. Surfers or swimmers are mistaken for more natural prey such as seals, which spend a lot of time on the surface.

Feeding is not the reason sharks attack humans. In fact, humans do not provide enough high-fat meat for sharks, which need a lot of energy to power their large, muscular bodies.

Yes, sharks do attack divers, whether provoked or unprovoked. However, attacks are extremely rare, as sharks don’t view scuba divers as a particularly appetizing prey. Most sharks are cautious of divers although, over the years, sharks have become bolder around people because of baiting.

They would have avoided tall cliffs and wild animals because they knew those threats could potentially kill them, and that’s what kept them alive. They learned fear as an adaptation to protect themselves. Biological things like animals are something that we’re very prone to fear.” Sharks still seem pretty scary.

Sharks do, however, have an acute sense of smell and a sensitive olfactory system–much more so than humans. It has often been thought that predators like sharks can smell fear. Sharks have nostrils that they only use to smell. Sharks do not smell fear, they can smell ANY trace amount of blood from miles away. …

Sharks have been known to attack humans when they are confused or curious. If a shark sees a human splashing in the water, it may try to investigate, leading to an accidental attack. Still, sharks have more to fear from humans than we do of them.

But, if a shark is near you in the water, stay calm and don’t flail your arms. Experts say the best thing to do is to swim slowly and keep eye contact with the shark. They say the only time you should defend yourself is if a shark looks aggressive. In that case hit either its nose, eyes, or its gill openings.
