At just over 100 meters, this is the maximum diving depth of the blue whale, the largest animal on Earth.

No, that's not a piece of dust on your screen. That's Herbert Nitsch during his record-setting free dive of 214 meters!

See that little dot right above this text? That's Nuno Gomes! At 318.25 meters, he currently holds the record for the world's deepest verified scuba dive.

At about 600 meters beneath the surface, we've arrived at what is known as the Twilight Zone. Temperatures here can be as low as 3.9 degrees celsius!

At just over 825 meters, Burj Khalifa, the tallest building in the world, would be completely submerged at this depth. And we're only just getting started.

Notice the softly glowing lights above. Those are deep sea anglers - they live their entire lives in almost total darkness. The water is freezing cold at this depth.

We've reached the 1,100 meter mark. This is the point beyond which visible light cannot penetrate. There is only darkness below...for miles.

Well, we're now exactly one mile under the sea. Very few creatures live at this depth due to the harsh conditions. For instance, the water pressure is so great that a human would be instantly crushed into nothingness if exposed. Nice.

Still here? We're not even halfway to the bottom yet. It's not too late to back out!

This is the maximum diving depth of a Sperm Whale. They spend over 90 percent of their lives at great depths in search of squid and small fish to eat.

The final resting place of the Titanic finds its home here at around 3700 meters under the sea. There have been 197 expeditions to this ghostly historical site.

At just over 2 miles, this is the average depth of the Atlantic Ocean. The pressure here is over 370 times that which is found on the surface.

The ocean is pitch black and silent at this point, with few living creatures. Some small, pale fish are at this depth, but they are few and far between.

At 5,642 meters under the sea, we are now so deep that the entirety of Mount Elbrus, the tallest peak of the Caucasus Mountains in Europe, would be completely submerged.

At 6,492 meters, we've reached the depth of Shinkai 6500, a Japanese deep-submergence vehicle. It dives to this depth in order to study seafloor topography and geology and to research deep-sea organisms.

We're now nearly 7,800 meters below the surface. This is the home of the Hadal Snailfish, which was until late 2011 the deepest that scientists had ever found fish before. This fish contains a protein that allows its cells to remain functional at the high pressures found in the sea.

We are at the deepest point of the sea where scientists have found fish. While the species of fish was unidentified, scientists theorize that the deepest similar species could go is to about 8,200 meters. However, there could be unknown organisms that live deeper.

We've reached the deepest part of the Atlantic Ocean. While this is incredibly deep, we'll soon see that there do exist many other places that are far deeper.

At 8,848 meters, we have a point in the sea that is deep as Mount Everest is tall. This is nearly 5 and a half miles beneath the surface of the ocean.

Standing at around 373 meters tall, the Empire State Building could be completely submerged at this depth nearly 25 times over.

At just over 9,400 meters, we've reached a depth equivalent to the average cruising altitude of an airliner.

We've reached a depth of 10,700 meters. It is around this depth that the world's deepest oil drilling sites, Deepwater Horizon, was active until the 2010 disaster that resulted in it becoming inoperable.

We're approaching the lowest known point in the sea. Even at this depth, life is prosperous in the form of soft, single-celled organisms that resemble some of Earth's earliest life forms.

It is at this depth that we find the lowest known point in the sea, otherwise known as Challenger Deep of the Mariana Trench. It is thought that there are other points that are much deeper, as we have only currently explored about 10 percent of the world's oceans.
