‘Megalodon 100 tonne shark’ filmed in Mariana Trench The Carcharocles megalodon, better known as the megalodon, was the world’s biggest-ever shark, whose name means big tooth. The Megalodon has since gone extinct but shark experts worldwide are still discovering its monstrous teeth.

On 23 January 1960, two explorers, US navy lieutenant Don Walsh and Swiss engineer Jacques Piccard, became the first people to dive 11km (seven miles) to the bottom of the Mariana Trench.

Researchers in the U.K. have revealed the true size of the megalodon, the prehistoric giant shark of Hollywood fame. Scientists can now reveal the size of the rest of the megalodon’s body, including its huge fins. The researchers note that megalodon fossils are typically huge triangular teeth larger than a human hand.

A recent study revealed that a plastic bag, like the kind given away at grocery stores, is now the deepest known piece of plastic trash, found at a depth of 10,975 meters (36,000 feet) inside the Mariana Trench.

Surviving a trip down to the Mariana Trench is pretty easy, as long as you can afford a fancy submarine. Some companies have even started bringing tourists down there.

The organisms discovered in the Mariana Trench include bacteria, crustaceans, sea cucumbers, octopuses and fishes. In 2014, the deepest living fish, at the depth of 8000 meters, Mariana snailfish was discovered near Guam.

While thousands of climbers have successfully scaled Mount Everest, the highest point on Earth, only two people have descended to the planet’s deepest point, the Challenger Deep in the Pacific Ocean’s Mariana Trench.

Originally Answered: What would happen to the human body if someone exited a submarine at the bottom of the mariana’s trench (-36000 feet)? The person’s lungs would be crushed unless they were equipped with a SCUBA tank and mask charged up to that enormous pressure.

The deepest point ever reached by man is 35,858 feet below the surface of the ocean, which happens to be as deep as water gets on earth. To go deeper, you’ll have to travel to the bottom of the Challenger Deep, a section of the Mariana Trench under the Pacific Ocean 200 miles southwest of Guam.
