Are there monsters at the bottom of the ocean?

Hundreds of years ago, European sailors told of a sea monster called the kraken that could toss ships into the air with its many long arms. Today we know sea monsters aren't real--but a living sea animal, the giant squid, has 10 arms and can grow longer than a school bus.

Are there creatures at the bottom of the ocean?

Creatures that inhabit the abyssal zone include chemosynthetic bacteria, worms, small fish, and certain shark species. Small fish, worms, and certain shark species live in the abyssal zone three miles below the surface.

What creature lives deepest in the ocean?

Scientists today formally documented the world's newest, deepest fish, Pseudoliparis swirei, an odd little snailfish caught at 7,966 meters in the Mariana Trench—nearly twice as far below the sea's surface as Wyoming's Grand Teton towers above it.

What's at the very bottom of the ocean?

Under the depths of the ocean, there are mountains, canyons, hot springs, lakes and hillsides. It's not just an unknown landscape to explore for the sake of beauty — the deep sea floor contains many minerals that can be useful to us on land.

Have humans been to the bottom of the ocean?

But reaching the lowest part of the ocean? Only three people have ever done that, and one was a U.S. Navy submariner. In the Pacific Ocean, somewhere between Guam and the Philippines, lies the Marianas Trench, also known as the Mariana Trench.

What Did Scientists Really See In The Mariana Trench?

How far has a human gone in the ocean?

Victor Vescovo, a retired naval officer, made the unsettling discovery as he descended nearly 35,853ft (10,927 meters) to a point in the Pacific Ocean's Mariana Trench that is the deepest place on Earth, his expedition said in a statement on Monday.

Why can't you go to the bottom of the ocean?

“The intense pressures in the deep ocean make it an extremely difficult environment to explore.” Although you don't notice it, the pressure of the air pushing down on your body at sea level is about 15 pounds per square inch. If you went up into space, above the Earth's atmosphere, the pressure would decrease to zero.

How dark is the bottom of the ocean?

Light may be detected as far as 1,000 meters down in the ocean, but there is rarely any significant light beyond 200 meters. The ocean is divided into three zones based on depth and light level.

What is the largest deep-sea creature?

The largest underwater species is the blue whale, which weighs 242,500 pounds on average and has a length of 79 feet.

How cold is the bottom of the ocean?

Therefore, the deep ocean (below about 200 meters depth) is cold, with an average temperature of only 4°C (39°F). Cold water is also more dense, and as a result heavier, than warm water. Colder water sinks below the warm water at the surface, which contributes to the coldness of the deep ocean.

What is the dark part of the ocean?

The abyssal zone or abyssopelagic zone is a layer of the pelagic zone of the ocean. "Abyss" derives from the Greek word ἄβυσσος, meaning bottomless. At depths of 4,000 to 6,000 metres (13,000 to 20,000 ft), this zone remains in perpetual darkness. It covers 83% of the total area of the ocean and 60% of Earth's surface.

Is there a giant creature in the ocean?

While the blue whale is the overall-largest creature of the sea, the lion's mane jellyfish goes to the top of the list for being the longest. These languid beauties have tentacles that reach an astonishing 120 feet in length.

What is the biggest thing to ever live in the ocean?

#1—Blue Whale

Coming in at #1… the blue whale! Not only is the blue whale the largest animal to live on the Earth today, they are also the largest animal to have ever existed on Earth.

Are there giants at the bottom of the ocean?

In the deepest and coldest parts of the ocean, sea creatures — mainly invertebrates, or animals without backbones — can reach gargantuan proportions. Squids, sea spiders, worms and a variety of other types of animals grow to sizes that dwarf related species around the world. The phenomenon is called gigantism.

Can you survive at the bottom of the ocean?

(2) There's no air. You can't breath at the bottom of the ocean. If you can't breath, your body won't stay alive for more than about 30 minutes. (Although you'd lose consciousness after about 5.)

What is the biggest predator in the ocean?

Killer Whales

But the true ruler of the sea is the killer whale. Killer whales are apex predators, which means they have no natural predators. They hunt in packs, much like wolves, which are also at the top of their food chain.

Is kraken real?

The Kraken Is Real: Scientist Films First Footage Of A Giant Squid For thousands of years, sailors have told stories of giant squids. In myth and cinema, the kraken was the most terrible of sea monsters. Now, it's been captured — on a soon-to-be-seen video.

Does the bloop exist?

"The Bloop" is the given name of a mysterious underwater sound recorded in the 90s. Years later, NOAA scientists discovered that this sound emanated from an iceberg cracking and breaking away from an Antarctic glacier. Shown here: a NASA Landsat mosaic image of Antarctica.

What is the deepest spot on Earth?

The Mariana Trench, in the Pacific Ocean, is the deepest location on Earth. According to the Exclusive Economic Zone (EEZ), the United States has jurisdiction over the trench and its resources. Scientists use a variety of technologies to overcome the challenges of deep-sea exploration and explore the Trench.

Can you swim in the ocean at dark?

Sharks Are Most Active On Beaches At Night

Sharks are most active during the night or at dawn or dusk hours. While humans have decreased visibility at night at the beach, a shark will not. It simply isn't worth the danger to try swimming in the ocean during the night!

What ocean floor looks like?

Like dry land, the ocean floor has various features including flat plains, sharp mountains, and rugged canyons (Fig. 7.1). However, the lowest point in the world ocean is much deeper than the highest point on land. The ocean floor is continually being formed and destroyed.

Is there an ocean under the ocean?

Hidden inside the Earth—within the first several hundred kilometers below the crust—there is another ocean. It is, most likely, the largest ocean in the world. This water is not sloshing around in a big pool.

Can the ocean pressure crush you?

Water cannot be compressed, or squeezed, by pressure like air can. This means that animals in the sea can stay safe when in the depths of the sea, as their body is balanced with the pressure around them, whereas we have air in our bodies that would be crushed.

Why can't you swim straight up in the ocean?

Moving upwards slowly while breathing avoids any issues, but shooting to the surface or holding your breath while swimming upwards can cause the lungs to over-expand and burst, sending gas into the bloodstream, causing an arterial gas embolism on its own.

What's the deepest someone has gone in the ocean?

Last year an expedition to the Mariana Trench made history by conducting the deepest crewed dive ever completed as it descended 10,927 metres into the Challenger Deep.
